UN Data
UN Data brings the statistical databases of the United Nations system together behind one search interface, so you can query across agencies without visiting each one separately. It spans 32 databases and more than 60 million records reaching back to 1970.
The coverage is broad: greenhouse gas inventories, commodity trade statistics, energy production and consumption, gender statistics, and headline development indicators. Because each underlying database is run by a different UN body, reuse terms vary by source. Most are generally open, but check the conditions attached to the specific database you are drawing from.
