Data link roundup (week of February 1, 2013)

The week's top data analysis links...

FOREIGN BORN

This week three links about the foreign-born population in the United States stood out for their clarity:

1. The Pew Research Center released new data, from the 2011 American Community Survey, on characteristics of the foreign-born population in the United States.
2. Slate explained how demographers develop estimates of unauthorized migrants.
3. NPR news explained the difference between the terms illegal immigrant, undocumented, and (my preference) unauthorized migrant.

DELINQUENT IN DETROIT

A new online mapping tool illustrates the persistent problem of urban decline in Detroit. The map shows properties that are delinquent (yellow) in foreclosure for delinquent taxes (orange) or foreclosed (red).

A summary in The Atlantic Cities reports that more than 150,000 (39%) of the city's 384,861 properties are in tax distress. The map illustrates the magnitude of the problem.
