  1. ¥ Live children only; sd – standard deviation
  2. Descriptive statistics are stratified by time to mine activation (i.e., ten years before the extraction) and the DHS clusters’ distance to the mining sites. Data from 72 Demographic and Health Surveys from 23 SSA countries. The included DHS data was collected between 1992 and 2018 and restricted to clusters within 50 km from isolated mines (i.e., mines separated at a minimum distance of 20 km from each other). All measures represent unweighted sample proportions
