Several years ago the Census Bureau added a “what year were you married” question to the American Community Survey. This was an uncontroversial change to the questionnaire because it helped shore up data on marriages.
See link from the IPUMS for all the new marriage/divorce timing variables
The CDC used to collate marriage and divorce certificate data from state vital statistics offices, but ceased this operation in the mid-1990s due to budgetary constraints [See sad note to this effect].
Here is a nice illustration from Philip Cohen’s Family Inequality blog on using these data to find out how many World War II “war brides” are still alive.

Why should NSF fund political science? Here’s a great reason:
United States Congressional District Shapefiles
Jeffrey B. Lewis, Brandon DeVine, and Lincoln Pritcher with Kenneth C. Martis
This site provides digital boundary definitions for every U.S. Congressional District in use between 1789 and 2012. These were produced as part of NSF grant SBE-SES-0241647 between 2009 and 2013.
The current release of these data is experimental. We have had done a good deal of work to validate all of the shapes. However, it is quite likely that some irregularities remain. Please email firstname.lastname@example.org with questions or suggestions for improvement. We hope to have a ticketing system for bugs and a versioning system up soon. The district definitions currently available should be considered an initial-release version.
The FY2014 budget for BLS has cut two important data programs: The Quarterly Census of Employment and Wages and the International Price Program. The latter is a principal economic indicator.

Blexting is short for “blight texting.” It is an app that a Detroit-based start-up (Loveland Technologies) created, which is being used to map all Detroit structures to fight blight. Here’s a bit of the coverage of the software and the amazing progress the blexters have made in mapping Detroit blight:

Bob Groves is no longer the Census Bureau director, but the Census Bureau’s plans for the 2020 Census have many of the elements that he wrote about in the Census Bureau’s Director’s blog and presented at professional meetings. He has had a lasting impact at the Census Bureau.

A recent memorandum from the White House, encourages the use of administrative data by federal agencies for statistical purposes. This may prove useful to some of the 2020 efforts.

Finally, the reference to “updated guidance” in the Pew piece sounds quite a bit like paradata used in responsive survey design of the NSFG. The Census enumerates all households so it isn’t a survey, but paradata can guide the data collection process – when to enumerate (weekend or not, evening or not) and when to get data from other sources.

Here are two reports on inequality – one for states, including historical data and one for the 50 largest cities. The state-based analysis uses state-level tax data whereas the city-based analysis uses the American Community Survey. The city-based study is referenced in a story in the New York Times.

The Census Bureau has released county to county migration flow data from the 2007-2011 ACS. This allows researchers to look at outbound, inbound, and net migration flows by selected characteristics (education, household income, and individual income).
Perhaps, Governor Snyder had advance access to these data before his state-of-the-state address as the only positive net value for Wayne County (and Michigan) is “movers from abroad.” Wayne County has a net loss of 28,000 to other Michigan counties and a net loss of approximately 17,000 to out of state counties. It has about one-third of Michigan’s movers from abroad (7,620 out of 24,715).

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.
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.
