The Brookings Institution uses data from the IRS to construct a broad database of tax return data, available by ZIP code, city, county, metropolitan area, state, state legislative district, and congressional district, for every year from 2000 to 2006. The data is available in PolicyMap in the "Money & Income" tab, in the "Federal Tax Returns" section. Due to privacy concerns, some areas with very low counts have suppressed data. Listed here are the top 10 zip codes that do not contain suppressed data.

Each month we release the Bureau of Labor Statistics’ preliminary and final unemployment rates. Unlike the national figures, the preliminary data on PolicyMap lags by about a month because BLS releases the city, county metro area and state level data one month behind the national numbers. The final figures lag by about two months. This data is free on PolicyMap and can be viewed in maps, tables, and trend charts.
