Measuring Social Sustainability for Socially Sustainable Urban Development: A Preliminary Study in Dhaka City, Bangladesh

Social sustainability in socially sustainable urban development is an escalating global concern to ensure the well-being of urban society. Uncontrolled and rapid urbanization has transformed Dhaka into one of the world's largest megacities, leading to severe social problems. Therefore, it influences the city's social sustainability. Due to the lack of attention to social sustainability, especially in cities of developing countries, this study aims to measure the current status of social sustainability in Dhaka city for socially sustainable urban development. A structured questionnaire survey was conducted among residents of Dhaka. Results revealed that Dhaka city residents have low satisfaction levels regarding social sustainability conditions. They are not getting adequate facilities related to social sustainability for socially sustainable urban development. The results provide empirical evidence of the current status of social sustainability to policymakers, urban planners, and implementing agencies in Dhaka city that can assist in formulating appropriate socially sustainable planning, policy formulation, and practical implementation. The study might also help researchers in developing countries expand their thinking about other cities encountering similar problems.


INTRODUCTION
Over the past 35 years, sustainable development has been introduced into the global arena as a key concept.Sustainable urban development evolves from the concept of sustainable development, which has also been receiving high attention among academics, urban planners, and policymakers recently (Wang et al., 2019;Larimian et al., 2020).United Nations Report of the World Commission on Environment and Development: Our Common Future stated that sustainable development depends on three dimensions, namely environment, economics, and social (United Nations, 1987).These three dimensions are also equally vital for sustainable urban development (Rafieian & Mirzakhalili, 2014;Baffoe & Mutisya, 2015).Despite the equal importance of the three dimensions in the sustainability agenda, social sustainability is constantly receiving less attention in academic literature (Haji Rasouli & Kumarasuriyar, 2016;Akan & Selam, 2018;Kumar & Anbanandam, 2019).Though social sustainability has become highly associated with sustainable urban development issues (Ali et al., 2019).
Recently, the socially sustainable urban development concept is gaining widespread attention in the literature with a greater emphasis on social aspects (Cho et al., 2015;Shirazi & Keivani, 2019a;Ring et al., 2021;Wrangsten et al., 2022).However, implementing social sustainability for socially sustainable urban development is challenging due to the growing trend of rapid urbanization.The world's population is growing significantly in urban areas.More than 76 per cent of urban people live in developing countries; it is forecast to be more than 83 per cent in 2050, while only about 16 per cent will live in developed countries (United Nations, 2019).Notably, the rapid urban expansion will decrease in developed countries and increase in developing countries.Rapid urbanization in most developing countries leads to severe social problems within urban areas (Zhang, 2016;Ghalib et al., 2017).Therefore, it is essential to reveal the social sustainability status for socially sustainable urban development in the cities of developing countries.
The context of Dhaka, as a city in a developing country, is also facing excessive urban expansion in the last few decades.In the previous 40 years, uncontrolled and rapid urbanization has made Dhaka one of the world's megacities with experienced massive population growth (Roy et al., 2018).Due to rapid urbanization, the urban community of Dhaka is immensely struggling with social problems, including standard housing, urban poverty, health facility, women empowerment, public transport, sanitation, shelter, illiteracy, slums, corruption, and open spaces (Satu & Chiu, 2019;Yasmin, 2019;Barai, 2020).The Theory of Urbanism also explained that rapid and unplanned urbanization creates extreme urban social problems (Wirth, 1938).The social problems are responsible for ensuring social sustainability that hinders sustainable urban development for city dwellers (Woodcraft, 2012;Ali et al., 2019).Hence, social sustainability requires adequate attention for socially sustainable urban development, which cannot be ignored, especially in cities in developing countries.
The present study is evidence-based research that contributes in a specific way to the existing literature.First, this is the first attempt to measure the current status of social sustainability in the context of Dhaka city based on the highest to lowest ranks of social sustainability themes.Previous studies focused on the assessment of social sustainability, but none of the studies specifically revealed the highest to the lowest rank of social sustainability themes.Therefore, this study contributes to this body of knowledge by obtaining concrete empirical evidence about the current status of social sustainability in Dhaka city that helps the government, policymakers, urban planners, urban municipalities, and implementing agencies in making appropriate plans, policy formulation, and practical implementation for a socially sustainable Dhaka city.Likewise, it helps them identify which social sustainability themes need to be addressed immediately.Second, this study is useful for those cities in developing countries facing the same problem as substantial urban social problems by rapid urbanization.Rapid urbanization is not only a concerning issue for Dhaka city but also, many other cities are facing the same situation, such as Kolkata, Delhi, Shanghai, Beijing, Mumbai, Osaka, Beijing, Cairo, and so on (United Nations, 2014).Third, this study also helps to achieve Sustainable Development Goals (SDG-11) titled "Sustainable Cities and Communities".

Social Sustainability Concept
In the late 1990s, social sustainability was a fundamental aspect of the sustainability agenda (Haji Rasouli & Kumarasuriyar, 2016).However, considering so far, there are five specific reasons why social sustainability is getting less priority.First, some theoretical arguments for defining social sustainability and even limited literature focus on this subject (Dempsey et al., 2011).Second, social sustainability still overlaps with the other two pillars of environmental and economic sustainability (Vallance et al., 2011).Third, social sustainability is often not considered due to its qualitative nature, which makes it challenging to evaluate and implement (Al-Dahmashawi et al., 2014).Fourth, some literature still covers social sustainability as social capital, social cohesion, social inclusion, and exclusion (Dempsey et al., 2011).Fifth, it is hard to conceptualize and provide an integrated framework, mainly in sustainability studies (Al-Dahmashawi et al., 2014).
Meanwhile, the definition of social sustainability creates some debate in the development world (Weingaertner & Moberg, 2014).The acceptable definition of social sustainability is somewhat complicated due to overlapping with other subjects (De Fine Licht & Folland, 2019).From the beginning, the focus was on a sustainable environment, while limited literature paid less attention to social sustainability (Haji Rasouli & Kumarasuriyar, 2016;Rocak et al., 2016).Thus, there was no definite definition of social sustainability in academic literature (Weingaertner & Moberg, 2014).
However, the social sustainability focus has increased in recent years with the number of authors' contributions to this area, who have developed its conceptual definition and integrated it into broader sustainability theory and practice.Thus, the meaning of social sustainability is more specific than ever in the academic literature (Partridge, 2014;McGuinn et al., 2020).Sachs (1999) defines social sustainability as human needs such as equitable incomes, access to goods, services, employment, human rights, and the importance of democracy.McKenzie (2004, p. 12) illustrates that "Social sustainability is a life-enhancing condition within communities and a process within communities that can achieve that condition".Ali et al. (2019) describe social sustainability as achieving a better quality of life through the participation and interaction of community members.Therefore, social sustainability can be defined as a favorable condition for a society where every individual can achieve a quality of life by ensuring human needs that help create a healthy and livable community for the current and future generations.
Since 1990, sustainable development has been associated with 'sustainable cities' or 'sustainable urban development' (Hemani & Das, 2016).Thereby, socially sustainable urban development has gained growing attention in the world.According to Enyedi and Kovács (2006), the concept of socially sustainable urban development is different from sustainable urban development, with more emphasis on social aspects.Socially sustainable urban development is accomplished when social aspects such as community involvement, social cohesion, solidarity, fairness, equity, participation, empowerment, and access are ensured in urban areas (Ogunsola, 2016).Therefore, socially sustainable urban development can be defined as a society and an urban condition where social aspects are gaining importance and being ensured in sustainable urban development.

Nexus Between Theory of Urbanism and Socially Sustainable Urban Development
In developing countries, rapid urbanization has created social problems that influence social sustainability and challenge building socially sustainable urban development (Woodcraft, 2012;Hemani et al., 2017;Ali et al., 2019;Khatun, 2019).In 1938, the Theory of Urbanism focused on how a city has grown with large population size, density, and heterogeneity due to rapid urbanization, leading to urban social problems.According to Wirth (1938), urbanisation in modern times makes extreme changes in almost every phase of urban social life.Consequently, he also mentioned that the rapid urbanization in the United States creates the intensity of urban problems.Eventually, urban social problems influence social sustainability (Hemani et al., 2017;Ali et al., 2019).In the context of cities in developing countries, ensuring the quality of life for the citizens becomes a severe issue for the city authorities as Wirth (1938) explained that rapid urbanization creates extra pressure on social life and increases the demand-pull of human needs.Therefore, social sustainability is crucial for ensuring socially sustainable urban development (Randeree & Ahmed, 2018;Timmerman et al., 2019;Saleem et al., 2020;Larimian & Sadeghi, 2021).
Before ensuring socially sustainable urban, measuring the current status of social sustainability for socially sustainable urban development in developing countries is essential.Measuring the current status of social sustainability helps to find out its actual conditions which assist city authorities to build socially sustainable cities. Considering this issue, this study intends to measure the current status of social sustainability for socially sustainable urban development in the context of Dhaka, as a city of developing countries.

Urban Social Sustainability in Dhaka City, Bangladesh
Urbanization is an effective process for global economic growth.Undoubtedly, urbanization brings economic benefits to a country, but adverse effects of rapid urbanization occur, especially in developing countries like Bangladesh.The urbanization pattern of Bangladesh has changed rapidly due to ruralurban migration (General Economic Division, 2016-2020).However, the pattern of urbanization was quite different for Bangladesh in 1950; 4.28 per cent of the population was living in urban areas, whereas the number of people in rural areas was 95.71 per cent.United Nations (2018b) forecasted that around 60 per cent urban population will live in 2050, whereas the rural population will be 40 per cent.Dhaka is the capital city of Bangladesh.The urbanization process in Dhaka city has become a megacity and suffering from the extensive growth of the population in recent decades.RAJUK (2015) stated that Dhaka's population increased by 63 per cent of the city's total growth due to migration, whereas only 37 per cent of growth happened from the natural increase.The trend of rural-urban migration in Dhaka creates a large population responsible for rapid urbanization.
The population and density growth started in Dhaka in 1971 (Roy et al., 2019).In terms of the total population living in urban areas, Dhaka ranked 9 th out of 10 top cities in 2018 and is forecasted to rank 4 th in 2030 (United Nations, 2018a).Dhaka has a population density of 41,000 per square kilometre, ranked 1 st among the world cities to build urban areas by population density per square mile (Demographia, 2019).The city has grown with large population size, density, and heterogeneity, leading to urban social problems.As a result, Dhaka is struggling with high population density through rapid urbanization, which creates social problems and affects the status of social sustainability (Rahman, 2014;Roy et al., 2021;Khatun, 2019).
Currently, the sustainability issue in Dhaka city is getting significant concern to the city planner and the government (RAJUK, 2015).Due to this fact, it becomes difficult for city management authorities to ensure the quality of life for the citizens of Dhaka city (Degert et al., 2016;Wang & Sarker, 2020).Indeed, building a sustainable urban requires serious attention to social problems to ensure social sustainability (Ali et al., 2019).In 2019, the 'Safe Cities Index' depicted the nature of urban safety based on four indicators: digital, infrastructure, health, and personal safety; Dhaka ranked 56 th out of 60 cities, which stands as the 5 th least safe city (The Economist Intelligence Unit, 2019).Numbeo (2021) presents the quality-of-life index based on the cost of living, housing affordance, crime rate, health system, traffic, and pollution, where Dhaka ranks 238 th out of 241 cities.Thus, measuring the current status of social sustainability is a prime issue for socially sustainable urban development in Dhaka city.Razia et al.

Study Area
The study considered Dhaka city as a study area.Dhaka city is located at 23°42′ to 23 o 52' latitude in the north and the 90°22′ to 90 o 32' longitude in the east (Roy et al., 2018).The total coverage area of this city is 302.92 square kilometers (Bangladesh Bureau of Statistics, 2013).Dhaka City Corporation has a self-governing system called the local government to manage the megacity.Dhaka City Corporation is divided into two city corporations: Dhaka North City Corporation (DNCC) and Dhaka South City Corporation (DSCC).

Population and Sample of the Study
According to the constitution of Bangladesh, when a citizen reaches the age of 18, they can participate in important decision-making events like national elections.Accordingly, this study sets the criteria for voters of Dhaka city to participate in the online survey by providing feedback.Likewise, voters have living experiences that help to provide insightful opinions about social sustainability in Dhaka.The study considers all Dhaka city residents as a population; only the voters are considered a target population.Due to the large population and financial and time limitations, a manageable sample size is required as it is difficult for the researcher to collect data from each voter.Johanson and Brooks (2010) suggest that 30 samples from the target population are reasonable for a pilot study.Finally, the researcher collected 109 responses from residents of two city corporations in Dhaka through an online survey for a pilot study.

Sampling Technique
This study adopted the multi-stage sampling technique to select its respondents.In the first stage, this study used the purposive sampling technique to select voters for participating in this online survey.In the second stage, this study also used the systematic sampling technique where we chose 06 wards from each city corporation to ensure the heterogeneity of the respondents' opinions.In the third stage, this study used a systematic sampling strategy to select the target respondents' houses, specifically for voters by collecting voters' information from the respective ward commissioner's office and the Bangladesh Election Commission.Hence, we excluded 11 responses to ensure voters' status from the 120 responses.
Finally, this study selected 109 respondents for the pilot study.

Data Collection Processes
A survey technique was used for this study to collect primary data through a structured questionnaire.We distributed well-prepared leaflets to selected wards of two city corporations to participate in the online survey through Google Docs.

Research Instrument
The study developed a measuring framework of social sustainability based on the comprehensive literature review, Commission on Sustainable Development Framework, Sustainable Development Goal-11, and National Urban Sector Policy for Bangladesh.Initially, 64 indicators were selected under 11 social sustainability themes, namely 1) Health Facilities, 2) Gender Equality and Women's Empowerment, 3) Urban poverty and Slums Improvement, 4) Urban children, aged, the disabled, and the scavengers, 5) Transportation Availability, 6) Satisfied with Space, 7) Open Space, 8) Social Capital, 9) Safety, 10) Social Justice, and 11) Education Facilities.A five-point Likert scale (i.e., 5-Strongly agree, 4-Agree, 3-Neither agree nor disagree, 2-Disagree, 1-Strongly disagree) 1 was used in the survey questionnaire where respondents were required to respond to the items.
A pre-testing procedure needs to be conducted to develop a survey questionnaire or confirm the variables' measurability (Hilton, 2017;Ikart, 2019).This study followed the pre-testing procedure by measuring the content validity of the survey questionnaire (see details in Appendix A).To check the content validity for the individual item (I-CVI) and overall scale (S-CVI) scores, a structural questionnaire was placed on 06 experts who are highly experienced and top authorities, including Directors of Urban Planning and Development, City Planners, Consultants, and Program Analysts from national and international platforms with four scale degrees of relevance (consistency, representative of concepts, relevance to concepts, and clarity in terms).As per experts' suggestions, 01 items have to be merged with other existing items, and 02 items were suggested to be rearranged.Finally, based on experts' comments and relevance ratings, 62 items were selected under 11 variables for the pilot study (variables and items are shown in Appendix A).
Skewness and kurtosis explicate the normal distribution of a dataset (Hair et al., 2022).This pilot study performed a normality test by checking skewness and kurtosis values (see details in Appendix B).All the skewness and kurtosis values were within the threshold level (±2), except in Open Space (OS).As per the kurtosis values, three items, i.e., OS1 (public space availability), OS2 (use of public space), and OS4 (satisfaction level of public space), exceeded the threshold level (± 2).However, the skewness values for OS2 and OS4 were within the threshold level range (± 2).Only the skewness and kurtosis values exceeded the threshold level for OS1.Only 01 (OS1) out of 62 items exceeded the threshold for skewness and kurtosis values.Though it is not significant, the assumption of normality based on the results of skewness and kurtosis implies that the data is not normally distributed.
The reliability of the adopted items was measured using Cronbach's Alpha to examine the quality of the research instruments.Straub et al. (2004) have suggested that reliability results should be considered equal to or above 0.60 for a pilot study.Table 2 demonstrates the result of the reliability analysis of the pilot study.The overall Cronbach's Alpha value was 0.948 with 62 items.Likewise, variable-wise, Cronbach's Alpha was also calculated to ensure the reliability of this pilot study.Cronbach's Alpha values for all individual variables ranged from 0.643 to 0.887, revealing that 10 out of 11 variables were obtained greater than 0.70, indicating significantly higher reliability.Only 01 out of 11 attained Cronbach's Alpha values greater than .60,which is considered acceptable.Therefore, all the measuring variables meet the required threshold value of Cronbach's Alpha which is adequate, valid, and reliable for this study.

Data Analysis
This study used the Social Package for Social Science (SPSS) and MS Excel to analyze data.To check the content validity, this study calculated I-CVI and S-CVI scores.Reliability was measured to assess the internal consistency of items, and Skewness and Kurtosis values were tested to check the assumption of normality for an individual variable.We used frequency distribution to get an overview of respondents' demographic profiles and descriptive statistics like Mean and Standard Deviation to analyze all variables and items.Likewise, the Kruskal-Wallis H test was used as a supplementary analysis to examine possible differences between respondents' age, gender, education, living area, living years, and all the items of social sustainability (see details in Appendix C and D).

RESULTS
This preliminary study measured the current status of social sustainability in the context of Dhaka city using 62 indicators.The individual mean of items (see Table 3) and the overall mean of each theme were calculated, illustrated in Figure 1._____________________________________________________________________________________ Note: The mean of each theme is shown at the top of the '3D Glass Chart (3DGC)', rank paced within the 3DGC.

Figure 1. Current Status of Social Sustainability in Dhaka City
As shown in Figure 1, the social sustainability themes were ranked 1 to 11 based on the largest to lowest mean scores.The overall mean of 62 indicators was 2.35, representing the current status of social sustainability in Dhaka (see Table 3).The overall mean score implies 'Disagree' points on the Likert scale.The individual mean score of social sustainability themes (see detail Table 3) was discussed in the following paragraphs.Although EF achieved the highest rank, the residents' overall opinion was indifferent about Dhaka city's current educational facilities.Notably, the residents of Dhaka city are moderately satisfied with 03 items, i.e., EF1 (free and compulsory education at the primary level), EF2 (free secondary education for girls), and EF5 (awareness and advocacy programs) whereas EF3 (specific educational zones) and EF4 (arrangement of primary, non-formal, and vocational education) need to focus on ensuring adequate educational facilities within Dhaka city.
Rank 2: 'Satisfied with Space (SWS)' ranks 2 nd with a mean score of 2.90; there were 04 measurement items.The mean value of satisfied with space showed the 'Disagree' stance of the Likert scale.The result shows that the items SWS3 (climatic comfort of my house during summer) had the highest mean value of 3.03, whereas SWS1 (spatial organization of the house), SWS2 (size of the house), and SWS4 (climatic comfort of the house during winter) received the lowest mean scores of 2.87, 2.84, and 2.87, respectively.It means residents are relatively satisfied with the 'climatic comfort of the house during summer (SWS3)'.Moreover, city authorities and urban planners' attention should be paid to 'spatial organization of the house (SWS1)', 'size of the house (SWS2)', and 'climatic comfort of the house during winter (SWS4)' to ensure/implement satisfied with space for the residents of Dhaka city.

Rank 3:
To measure the current status of 'Transport Availability (TA)' in Dhaka city, 04 measuring items were used, ranking 3 rd with a mean score of 2.68.The findings revealed that item TA1 (reaching to bus stop easily from my home) received a higher mean value of 3.43 whilst TA3 (satisfaction level of public transportation) got a lower mean value of 1.91.The current condition of TA3 was not satisfactory among the residents of Dhaka city.Still, item TA1 was at a moderately satisfying level.To make a socially sustainable Dhaka, it is necessary to pay attention to all the items of transport availability.
Rank 4: 'Gender Equality and Women's Empowerment (GEWE)' is in 4 th rank with a mean score of 2.66, containing 07 measuring items.The items GEWE3 (women's employment opportunities) and GEWE2 (women's involvement in community development) had the highest mean value of 3.17 and 3.03, respectively, whereas GEWE6 (awareness initiatives for underprivileged women) and GEWE1 (gender-sensitive urban planning and management strategies) had the lowest mean value of 2.12 and 2.13, respectively.Overall, all gender equality and women's empowerment items except for GEWE3 and GEWE2 were below satisfactory levels, which require close attention from Dhaka city planners and policymakers.
Rank 5: 'Safety (SF)' was measured by 06 items with a mean value of 2.29, which ranked 5 th in the current status of social sustainability in Dhaka city.The items SF1 (feeling safe walking during the day in Dhaka), SF2 (feeling safe walking during nighttime in Dhaka), SF3 (my house is safe during travel time), SF4 (feeling safe while using public transportation in Dhaka), SF5 (feeling safe in my neighborhood), and SF6 (satisfaction level of safety) have obtained mean values of 2.78, 1.63, 2.25, 2.05, 2.25, and 2.78, respectively.All safety items belong to the lowest satisfaction level among Dhaka city residents.In particular, residents of Dhaka feel that their homes are not safe during travel (SF2).Overall, the current safety status is not satisfactory, which is expecting close attention from the government, and city management/implementation authorities to ensure the safety of all the residents of Dhaka city.
Rank 6: 'Social Capital (SC)' was measured by 08 items, ranking 6 th with a mean score of 2.22.Based on the results, SC3 (spending time with a neighbor) got the higher mean value of 3.27, whereas SC4 (chatting with neighbors) and SC5 (practicing social and ethical values) received the same mean value of 2.06.In addition, the mean score of SC1 (relationship with neighbors), SC2 (trusting neighbors), SC6 (year of residency), SC7 (plan to change their houses), and SC8 (plan to change it in the same neighborhood) were 2.32, 2.67, 1.75, 1.84, and 1.78, respectively.Based on the opinion of the Dhaka city residents, the significant concern is on the items SC6, SC7, and SC8, which are somewhat absent in Dhaka city.
Rank 7: 'Health Facilities (HF)' ranked 7 th with a mean value of 2.16, measured by 05 items.The highest and lowest mean values for HF2 (hospitals located in the residential areas) and HF1 (free primary healthcare service) items were 2.62 and 1.95, respectively.Free primary healthcare service for women and children (HF1) and arrangements for protecting against transmitted diseases like aids (HF4) indicated lower satisfaction levels among residents.Though, all the items belong to the low level of satisfaction that represents citizens of Dhaka city are not getting adequate health facilities.
Rank 8: The 8 th ranked acquired 'Social Justice (SJ)' with a mean value of 2.09; measured by 04 items.The items SJ1 (fair distribution of resources), SJ2 (equality of rights), SJ3 (equitable access for all people), and SJ4 (actively participating in communal activities and decision making) had a mean value of 2.26, 1.86, 1.98, and 2.24, respectively.Based on the results, residents believed that social justice has not been adequately implemented in Dhaka.Therefore, government, policymakers, city planners, and city management authorities must emphasize ensuring social justice in Dhaka city as social justice is necessary to make a city socially sustainable.
Rank 9: There were 06 measuring items to measure the condition of 'Urban Poverty and Slums Improvement (UPSI)', which ranked 9 th with a mean value of 2.08.The mean value for all individual items, i.e., UPSI1 (upgrading and improvement of slums), UPSI2 (slum dwellers' resettlement is implemented), UPSI3 (ensuring tenure security), UPSI4 (special zones for the urban poor), UPSI5 (equal access to the essential urban services), and UPSI6 (supporting informal sector activities) range from 1.96 to 2.32.Additionally, a significant consideration is required in all the items to improve urban poverty and slums.
Rank 10: 'Urban children, aged, the disabled, and the scavengers (UCADS)' were measured by 08 items and ranked 10 th with a mean value of 1.86.The mean value showed the 'Strongly Disagree' stance of the Likert scale.The mean value of all individual items, i.e., UCADS1(ensure basic needs for children), UCADS2 (infrastructural designs for the disabled), UCADS3 (safety of children against all forms of abuse), UCADS4 (extend services for the children of working mother), UCADS5 (enforce laws dealing with child labor), UCADS7 (equal access to street children, scavengers, the aged, and disabled people), and UCADS8 (city authority ensures shelter) ranges from 1.75 to 1.91 except for UCADS6 (promote programs to eliminate malnutrition) with the mean value 2.04.The result indicated the least satisfaction among the residents of Dhaka city as they believed that all UCADS items are absent to ensure a socially sustainable urban, which needs serious consideration currently.
Rank 11: 'Open Space (OS)' was measured by 05 items with a mean value of 1.81, ranking 11 th in terms of social sustainability in Dhaka city.All individual items, i.e., OS1 (public space availability), OS2 (use of public space), OS4 (satisfaction level of public space), mean values ranged from 1.54 to 1.71, except for OS3 (time to reach park) and OS5 (initiatives of recreational facilities for leisure).The result also showed that OS3 and OS5 had the disagreed position, and the remaining items were the least level of satisfaction for getting the facilities from open space in Dhaka city.As every city needs adequate open space for citizens' healthy livability, Dhaka's present open space condition is just a dream.

DISCUSSION
The study has developed a measurement framework for measuring social sustainability conditions in Dhaka city.The overall mean results reflected low levels of social sustainability satisfaction among Dhaka city residents.Specifically, the citizens of Dhaka city have shown the least level of satisfaction on two variables: urban children, the aged, the disabled, and the scavengers (UCADS) and open space (OS).On the other hand, variables appeared as moderate to low satisfaction levels on urban poverty and slum improvement, social justice, health facilities, safety, social capital, gender equality and women's empowerment, transportation availability, and satisfaction with space.Besides, education facilities received indifferent results regarding the current status of social sustainability in Dhaka city.Overall, analysis of the results revealed that the current situation of social sustainability is not satisfactory as its aspects are not getting that level of importance for ensuring socially sustainable urban development.
Since social sustainability is less focused, some studies have empirically measured it but had different purposes than this study.To exemplify, Dogu and Aras (2019) developed a measuring scale of social sustainability for Güzelyurt City, Northern Cyprus.The authors developed a measurement scale based on seven variables of social sustainability such as sense of belonging, social capital, perceived environment, social interactions/security, interaction with space, satisfied with space, voice, and influence.Based on the city of Güzelyurt, the variables of social sustainability were not found at a satisfactory level.Larimian and Sadeghi (2021) assessed social sustainability in Dunedin City, New Zealand's urban neighborhoods, and determined whether design quality influenced social sustainability.They used seven social sustainability variables, including social interaction, safety and security, social equity, social participation, neighborhood satisfaction, sense of place, and housing satisfaction, which revealed a significant positive relationship between quality of design and overall social sustainability.
Likewise, Ali et al. ( 2019) evaluated urban form's role in achieving better social sustainability results in Irbid, Jordan.Five features of urban form such as density, land use distribution, building height, type of housing, and accessibility were used to examine their impact on social sustainability variables such as access to services, open spaces, and parks, availability of transportation, job accessibility, social interaction, safety, residential stability, sense of belonging, and neighborhood as a place to live.Their findings revealed that urban form strongly impacted social sustainability as respondents' satisfaction was moderate to relatively low.
In addition, Yu et al. ( 2017) developed an assessment system to measure the social sustainability of urban housing demolition in Shanghai, China.They used 22 indicators to measure social sustainability.They found that health and safety, social equality, and adherence to the law must be considered critical in urban housing demolition's social sustainability.Therefore, this study measures the current status of social sustainability and found an overall low level of satisfaction with experiencing socially sustainable urban development in Dhaka; this city acts as an example of a developing country.The current status Razia et al.
of social sustainability should be measured by many other cities in developing countries that face the same problems of rapid urbanization.
Nonetheless, the limitations of this study are not to be overlooked.First, this study considered only 109 respondents from Dhaka city for a pilot study.Second, this study only used a questionnaire survey as a data collection method.Third, this study adopted all variables from the literature to measure the current status of social sustainability for socially sustainable urban development in Dhaka city.From the limitations of this study, there is a scope created for future researchers.For example, developing countries are concentrating less on this field of research.Researchers from developing countries could provide more effort to assess the social sustainability of socially sustainable urban development by including or considering many respondents for the large-scale study.In addition, mixed methods research allows the incorporation of different methods that help researchers to investigate various aspects of urban social sustainability.Furthermore, index development for social sustainability can be considered based on the city's culture and basic social needs.Overall, the study might help researchers in developing countries diversify their thinking on social sustainability for socially sustainable urban development.

PRACTICAL IMPLICATION AND CONCLUSION
Social sustainability for socially sustainable urban development is a prominent issue worldwide.Social sustainability is essential to ensure the longrun needs of people in a society.The lack of significance in social sustainability, especially in developing countries, increases the need for each stakeholder to know the current status of social sustainability.It helps to create insightful thinking for a socially sustainable urban for present and future generations.
From the result of the pilot study, all variables of social sustainability performed low satisfaction levels among Dhaka city's citizens.Notably, it appears that the current status of social sustainability is not in a good position for socially sustainable urban development in Dhaka city.Moreover, we empirically tested the framework to measure the current status of social sustainability regarding some demographic characteristics of respondents and found a statistically significant difference in respondents' age and gender.However, a study based on large sample size is required to confirm the results of this pilot study.
Based on the citizen's opinions and expectations on the current status of social sustainability in Dhaka city, it will help policymakers, urban planners, urban municipalities, and implementing agencies formulate specific solutions to make a socially sustainable urban.Moreover, this study can be an example for cities in developing countries where rapid urbanization creates social problems that influence the status of social sustainability.From this point of view, this study opens a further window for those cities facing similar problems that can use this measurement framework to identify the current condition of social sustainability.
