Abstract
Call detail records (CDRs) from mobile phone metadata are a promising data source for mapping poverty indicators in low- and middle-income countries. This study utilizes CDR data from Namibia, Nepal, and Bangladesh to map poverty and wealth patterns. Five metrics of user mobility and call behavior explain 50-65% of the variance in socioeconomic status nationally across these countries, demonstrating the generalizability of these metrics for poverty estimation. The study highlights the importance of ancillary data and local context in understanding model outputs for targeted poverty alleviation strategies.
