Verdict

FEWS NET and the Humanitarian Data Exchange both serve humanitarian analysts, but at different points in the workflow. FEWS NET is a specialist: a USAID-funded early-warning system producing its own monthly forecasts and IPC-compatible food-insecurity classifications for more than 30 countries. HDX is a generalist catalog: a UN OCHA platform hosting over 20,000 datasets from 1,900+ contributing organizations across displacement, health, conflict, and response indicators — including, in many cases, data that references or complements FEWS NET's own outputs. If your question is specifically about food insecurity, go to the specialist. If you need to find whatever data exists for a given crisis, start with the catalog.

Choose FEWS NET if

You need a forecast, not just a dataset — its outputs are analyst-produced food-insecurity classifications and outlook briefs, not raw survey data.
Your focus is specifically food security, agroclimatology, or livelihood-zone vulnerability.
You want a consistent, IPC-compatible classification system usable across the 30+ countries it covers.

Choose Humanitarian Data Exchange if

You need to search across many humanitarian topics and organizations at once, not just food security.
You want to find datasets contributed by other agencies (including some that draw on FEWS NET's work) rather than one program's own outputs.
You need programmatic access via an API or a tabular Data Explorer to pull structured data without manual file downloads.

The honest caveat

HDX's breadth is also its limitation: because it aggregates from 1,900+ contributing sources, the currency and quality of any individual dataset depends on whoever submitted it, not on OCHA itself. FEWS NET's forecasts, by contrast, come from a single consistent methodology, but the site itself notes its analysis does not represent official US government positions — treat it as expert analysis, not a government determination.
