Data is everywhere. Conversely, data is the most valuable commodity on earth, surpassing even oil, according to Britney Kaiser a former Cambridge Analytica employee who appeared in the Netflix documentary The Great Hack.

It is the analysis that makes data valuable. Without analysis, data is mostly worthless for humans. 

While companies have committed themselves to use their data for examination and interpretation, several organizations and government entities have made hundreds of datasets freely available to be used and analyzed by anyone willing to examine them. 

Companies that may not have the resources to begin accumulating their own data can access publically available data and start investigating the right questions and getting answers right away.

Below is a list of 30 data sets that are freely available to anyone. Many more are available for various niches. Chances are if someone collects it, follows it, or makes money from it, there may be a free dataset about it somewhere.
