Google Dataset Search

Across the web, there are millions of datasets about nearly any subject. Dataset Search has indexed almost 25 million of these datasets, giving you a single place to search for datasets and find links to where the data is. 

Some other options for finding datasets:

Dimensions - over 11 million datasets indexed, most but not all search functions on this site are free (UPEI does not have a paid subscription) a global registry of research data repositories, including some that are not free

Data Repositories Open Access Directory

US Govt: and another one specifically for health data:

Harvard Dataverse- about 150,000 datasets

The European Union's Eurocentric dataset search page

CESSDA (Consortium of European Social Science Data Archives)

OpenAfrica OpenAfrica is not a government agency but calls itself a grassroots movement to open Africa related datasets - just biomed/health related datasets
