INDEPTH member HDSSs generate huge quantities of high-quality, harmonised data on the health dynamics of the population under longitudinal evaluation. The ultimate goal is to ensure that these data and research evidence guide policy and planning processes at the national, regional and global levels. INDEPTH uses the data contributed by its member HDSSs to produce summary statistics that are made available on INDEPTHStats. Researchers and other interested persons who wish to do the analyses themselves can access the disagregated data on the INDEPTH Data Repository.
