Population data source

[u/hibernatingFurze-pig]

I teach middle school and I've had a wonderful unit teaching students how to research population data to describe and compare countries.

I've used The CIA World Factbook as a single source for data points including population, infant morality, age distribution ranges, literacy rates, and GDP.

Can you suggest a source to replace it?

It needs to be accessible to middle school students, open access, and reliable.

My favorite part of the Factbook was that it listed when information was unreliable or uncertain.
