Most of the charting data come directly from the servers of the U.S. Census Bureau
, the Bureau of Economic Analysis, and the Bureau of Labor Statistics. There are a few charts, however, that are based on data that are publicly available, but are not accessible through a public API. In those cases, the data are retrieved from Wyattopia databases. In any case, the actual datasource should be clearly identified on every chart.
All of the map data comes from TIGERweb
, a mapping service provided by the U.S. Census Bureau.
