Now-a-days, it is admissible to all that income is not only the measuring-rod of poverty. Scarcity of income is no doubt the fundamental cause of poverty. Adequate amount of income of an individual leads to alleviate economic poverty, however less effective to alleviate non-income related such as social poverty at all. Alleviating of social poverty alongside economic poverty is inevitable for a country’s overall sustainable development. The study attempted to assess the social impact of microfinance operations of BRAC on the life cycle of the clients. With the objective of measuring the social impact, randomly 208 clients who came under BRAC microfinance facilities were selected from a village. Comparative data tables between pre and post joining of BRAC microfinance operations were used to determine the social impact. The study underscored on four social aspects to measure the social impact of microfinance operations on the beneficiaries. Analysis of findings showed that the overall impact of microfinance operations in the social sphere was positive, though the extent of impact on the selected social aspects is not alike. For instance, an insignificant impact noticed on health, nutrition and family planning and a moderate impact on children’s education of the sample borrowers of microfinance. While a significant impact observed on potable water and on the sanitary condition (toilet facilities) of the respondents.
