The covariates used for matching include age, religion, literacy, spouse literacy house ownership, access to drinking water, access to gutter drainage, access to toilet facility, children, debt age, group loan, loan amount, interest rate and monthly meetings.

Matching is performed with one nearest neighbour in terms of propensity score.

*Significant at 1% level.
