The DHS Program vs World Bank Microdata Library

DHS is a focused program of household health surveys across ~100 countries; the World Bank library is a broader catalog spanning health, welfare, and more.

Verdict

Both the DHS Program and the World Bank Microdata Library give researchers free, registered access to household-level survey microdata from developing countries, and both require registration for some or all datasets. The difference is scope and ownership. DHS is a single, focused survey program — Demographic and Health Surveys, fielded consistently since 1985 with a common methodology, purpose-built for population, maternal and child health, nutrition, and HIV indicators. The World Bank Microdata Library is broader and more of a catalog: it hosts its own Living Standards Measurement Study collection alongside datasets contributed by partner agencies (UNHCR, UNICEF's MICS, and others), so coverage and consistency vary more by dataset.

Choose The DHS Program if

Your research question is specifically about population, maternal/child health, nutrition, or HIV.
You want a consistent survey methodology applied across nearly 100 countries and 400+ surveys, making cross-country comparison more reliable.
You want geographic coordinates and biomarker data linked to survey responses for spatial or clinical analysis.

Choose World Bank Microdata Library if

Your question is broader than health — poverty, welfare, financial inclusion, or general household economics.
You want access to the Living Standards Measurement Study or other specialized collections (Global Findex, SIEF impact evaluations) alongside DHS-adjacent partner datasets.
You're comfortable navigating varying access restrictions, since ownership of some catalogued datasets sits with the contributing agency rather than the World Bank itself.

The honest caveat

DHS microdata is free with registration and an approved use, but the program's continued operation has itself depended on emergency philanthropic funding after a 2025 US funding disruption — worth factoring into any long-term research plan built around it. The World Bank library's breadth comes at the cost of consistency: unlike DHS's single methodology, quality, documentation, and access terms vary by which agency originally collected each dataset.
