The present study provides field based socio-economic data of women slum dwellers in the city of Lucknow, the administrative capital of Uttar Pradesh, India. Being one of the most developed cities in Uttar Pradesh, Lucknow attracts a lot of migrants most of whom come for better economic opportunities and settle in the low-income neighbourhood of the city. Consequently, the number and population of slum colonies has grown simultaneously. In the present times, an increasing number of women migrate independently and are the principal wage earners for themselves and their families. However, since women come with limited job skills and other limited resources, many of them end up in urban slums wherein they remain at a disadvantage in terms of equitable access to work and other aspects compared to their male counterparts. In order to draw a holistic picture of the status of female slum dwellers, an exhaustive socio-economic field survey (2020-21) for 240 women respondents, across 21 slum colonies, was carried out, collecting data on 121 diverse aspects. This high granularity socio economic dataset can be used for carrying out interdisciplinary research as well as formulation and implementation of slum development and urban poverty alleviation programmes.
