New PUMA boundaries for the 2012 release of ACS data

The 2012 ACS releases (2012, 2010-2012, and 2008-2012) use new boundaries for PUMAs. These new definitions are based on new guidelines established by the Census Bureau as well as results from the 2010 Census.

PUMA Guidelines

The upshot of the guidelines is that the building blocks for PUMAs must be census tracts or counties. PUMAs can no longer be comprised of places or multiple places, especially as in the case of Michigan these multi-place PUMAs were sometimes comprised of non contiguous places.

The Census Bureau also encourages that the newly constructed PUMAs map to metropolitan areas.

The definition for the composition of PUMAs from the Census Bureau’s site is not all that informative. It is an Excel spreadsheet with the geographic identifier and Name of the PUMA, e.g., Northwest Detroit for PUMA 263208.

2010 Census Gazetteer Files: PUMAs

To know which census tracts are “Northwest Detroit” one needs to map census tracts to PUMAs. One can do this via the MableGeocorr site [Source: census tract; Target: PUMA2012].

Of course many PUMAs are comprised of multiple counties or a single county, so that sort of detail is not necessary for them. I will update this post later this week with a crosswalk, which includes “census tracts” for multi-PUMA counties and counties for single/combined county PUMAs.

The Geography of Intergenerational Mobility in the U.S.

From website:

Is America the “Land of Opportunity”? In two recent studies, we find that: (1) Upward income mobility varies substantially within the U.S. Areas with greater mobility tend to have five characteristics: less segregation, less income inequality, better schools, greater social capital, and more stable families. (2) Contrary to popular perception, economic mobility has not changed significantly over time; however, it is consistently lower in the U.S. than in most developed countries.

Widening racial disparity in breast cancer deaths

The New York Times has a great interactive visualization of the widening racial disparity in breast cancer deaths drawn from data from the Cancer Institute. Previously, black women had lower breast cancer mortality than whites, but it is now higher. The trend is not exactly the same across all states.

The New York Times article was inspired by a publication based on the trend in racial disparities in cancer mortality in the 25-largest cities in the US:

Economists in a Blizzard

Economists are at their annual meeting in the teeth of a big snowstorm. In case you missed the conference, here’s the presidential address by Claudia Golden on the cause of the remaining gender gap:

More relevant to PSC is that Martha Bailey and Brad Hershbein were awarded the IZA Young Labor Economist Award for their paper The Opt-In Revolution? Contraception, Fertility Timing and the Gender Gap in Wages.

And via Twitter, Justin Wolfers points to some job openings for economists – internet economist.
