Here you will find one of the greatest historical atlases: Charles O. Paullin and John K. Wright's Atlas of the Historical Geography of the United States, first published in 1932. This digital edition reproduces all of the atlas's nearly 700 maps. Many of these beautiful maps are enhanced here in ways impossible in print, animated to show change over time or made clickable to view the underlying data—remarkable maps produced eight decades ago with the functionality of the twenty-first century.

A team of economists from Harvard and UC Berkeley studying the effects of tax expenditures on economic mobility has released data showing that economic mobility in the U.S. varies dramatically between different geographic areas. The authors' website includes a summary of their findings. According the NY Times article on the study, which has a nifty map and tools to play with the data, the authors only found relatively small correlations between tax credits for the poor and higher taxes on the rich and economic mobility. However, the following four factors did correlate with greater economic mobility in a region: the size and dispersion of the middle class, more two-parent households, better schools, and more civic engagement (measured through membership in religious and community groups). Matthew Yglesias comments on the study at Slate. [more inside]

Dan Grover and Mike Belfrage have mapped transit inequality in the Bay Area after reading a New Yorker piece on the New York City subway (previously). The ways in which a widening income gap are changing the demography of San Francisco have been widely reported of late (previously, previously). The project's code is available if you'd like to try mapping your own city.

How segregated is your city? Eric Fischer maps the top 40 US cities by race, using 2000 census data. Each color-coded dot represents 25 people: Red is White, Blue is Black, Green is Asian, and Orange is Hispanic. The maps are oddly pretty, and revealing. Compare, for example, Detroit and San Antonio. via [more inside]
