This We Know is not a government site but is does display governmental data. The website collects information from www.data.gov and presents it in a format that is accessible.
For example, by typing in the zip code of 91106 I quickly found out that:
- How much pollutants were release in the air and by which companies within the zip code.
- How many people are unemployed in Pasadena, CA.
- How many factories are in the area.
At least, I hope so.
But if you like your data raw, massive and plum overwhelming there is nothing like going to the source, in this case the Data.gov Tools page:
On the Tools page is a gateway catalog of the hundreds of governmental websites providing statistical information, information resources and government resources.
You can search by category or by governmental agency. There is a lot of data here. Use what you can, it is for the taking.
