Dhaka slums occupies only 5.1% of the city's total land (1,542 hectares) accommodating 37.4% of the total city population. Methods. However, our shapefile in Dataset Item 1 (Spatial Data) is comparable to the latest population and housing census 2011 [39] in order to facilitate comparisons. Michael Frings and Anika Nockert helped in processing the data and also revised the paper critically. Mobarak Hossain Khan, Tobia Lakes, Patrick Hostert, "Mapping the Slums of Dhaka from 2006 to 2010", Dataset Papers in Science, vol. Kit, M. Lüdeke, and D.

Study of Morbidity and Utilisation of Healthcare among Slum Dwellers in Dhaka City", found that a vast majority of the slum population did not use soap for washing hands. UN-HABITAT (2006) reports that 79% of the population of Bangladesh’s larger cities live in them. All editing and processing were performed in ArcGIS 10 [22]. The dataset associated with this Dataset Paper consists of 5 items which are described as follows. It is one of the most densely populated areas in the world, with a density of 23,234 people per square kilometer within a total area of 300 square kilometers. Because these are usually situated in fragile low lying areas, the urban poor living in slums are highly vulnerable to natural disaster. Migration from rural areas of the country to urban Dhaka is an active contributor to the population growth. Figure 1). A previous study on urban slums in 6 cities in Bangladesh reported household conditions in Dhaka slums as follows: about 92% used piped water supply, 99% shared toilet, only 12% owned house, 46% lived in kutcha and 52% lived in semi-pucca . Many of the city’s immigrants initially concentrate in slums, due to poverty and limited alternatives [5]. Review articles are excluded from this waiver policy. In 1765, control of the city was handed to the British East India Company. Dhaka Slums: Where Covid is curiously quiet. Areas of heavy foliage cover that could obscure settlements were less common but likely contain the majority of false negatives. During British rule, schools, townships, and public works were developed, as well as a municipal water system in 1874 and electricity supply in 1878. The dataset presented here can be considered a stepping stone for further research of slums and urban expansion in Dhaka. The goal of this study was to present an attempt to acquire new large-scale spatial data on Dhaka slums efficiently through the use of remote sensing. The slum distribution dataset is useful to be pooled with other data to reveal trends of informal settlement growth for local health policy advice in Dhaka. Dhaka's population, now estimated at 15 million, is expected to hit 20 million by 2025. ESRI shapefile containing polygons that represent the delineations of slums larger than 1 acre in the Dhaka Metropolitan Area as seen in 2010 Quickbird images [28–36] along with the ward/union boundary shapefile derived from the CMS and adapted to fit with the names of the most recent census. Two censuses and many surveys on slum … Slum inhabitants have to deal everyday with lack of basic infrastructures such as drinking water, sewage and sanitation facilities, pollution and constant migration. Finally, the format “∗.shp.xml” contains the geospatial metadata of the shapefile, a descriptive document of the shapefile in xml format. Oliver Gruebner designed the study, guided the spatial analysis, and wrote the paper. Fourth, the slum size calculation per ward or union very much depends on the shapefile used for those administrative areas. Dataset Item 2 (Spatial Data). These data reveal the loss of slum settlements from areas previously containing slum. About 16 million people live in Dhaka alone and the number is projected to rise to 27 million by 2030. This study recovered a slum population of 718,143 in some 2,156 slum and squatter clusters. Six 2006 scenes were taken on January 6 [23–27]. [14] additionally differentiated the socioeconomic status of urban residential areas in central Dhaka using the normalized difference vegetation index (NDVI) from Quickbird data. This rural migration accounted for 60% population growth throughout the 1960s and 1970s. The fast-growing population has already put tremendous stress on the city, as evidenced by its high rates of poverty, and future concerns include increasing congestion, a higher percentage of unemployment and inadequate infrastructure. With some 400,000 new residents arriving each year from rural areas seeking a better life, Dhaka is straining under the pressure of its rapidly swelling population. However, like many other metropolises in the world, the growing population has led to an increase in pollution, congestion, and poverty, amongst other problems. The final slum datasets were created in three stages:(1)suspected slums were demarcated in ArcGIS over 2006 Quickbird satellite images;(2)using the previous output as a base, new slum additions and subtractions were then mapped over 2010 Quickbird images;(3)the 2006 and 2010 slums maps were compared and changes were mapped.2006 mapping procedure was as follows. However, fear is widespread, particularly after early April reports of Covid-19 deaths in Bangladesh. According to UN Habitat, Dhaka is the world’s most crowded city. Additional ground-verified data were derived from our survey of 15 Dhaka slums from 2007 to 2009 for diverse spatial-epidemiological studies [9–12, 21, 37]. 2010 scene georeferencing was adjusted to match the 2006 slums were mapped through the visual interpretation of Quickbird satellite from...
