Minimum Wage and Migration

By: Kirk Johnson
Source: New York Times

In the nation’s debate about the minimum wage, which President Obama has proposed increasing at the federal level to $10.10 from $7.25, this rolling borderland of onion farms and strip malls provides a test tube of sorts for observing how the minimum wage works in daily life, and how differences in the rate can affect a local economy in sometimes unexpected ways.

County-to-County Migration Flows

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).

Project Tycho: Historical Disease Data

Project Tycho is funded by NIH and the Bill and Melinda Gates Foundation. It has taken historical data from the National Notifiable Diseases Surveillance System (NNDSS) and created count data for diseases by location for the 125 year history of the surveillance system. Three levels of data have been made available to users from the Project Tycho website.

Other useful resources:

  • Materials and Methods: Digitication of US Weekly Surveillance Reports between 1888 and 2011
  • Preliminary State Reports (scroll down for access – here’s an example for Michigan)
  • What does Tycho stand for?
  • And, here is a paper published in the New England Journal of Medicine based on these data. It estimates that over 100 million cases of contagious diseases have been prevented in the U.S. since 1924 by vaccination programs against polio, measles, mumps, rubella, hepatitis A, diphtheria, and pertussis (whooping cough).

    Elderly Immigrants in the United States

    From the publication website:

    In 2010, more than one in eight U.S. adults ages 65 and older were foreign-born, a share that is expected to continue to grow. The U.S. elderly immigrant population rose from 2.7 million in 1990 to 4.6 million in 2010, a 70 percent increase in 20 years (see figure). This issue of Today’s Research on Aging reviews recent research examining older immigrants in the United States, conducted by National Institute on Aging (NIA)-supported researchers and others. Understanding both the unique characteristics of elderly foreign-born adults and the challenges some of them face is important as policymakers and planners address the well-being and health of the United States’ aging population.

    Demolition as an Urban Strategy

    Via The New York Times
    by: Timothy Williams

    Large-scale destruction is well known in Detroit, but it is also underway in Baltimore, Philadelphia, Cleveland, Cincinnati, Buffalo and others at a total cost of more than $250 million. Officials are tearing down tens of thousands of vacant buildings, many habitable, as they seek to stimulate economic growth, reduce crime and blight, and increase environmental sustainability.

    Visualizing Births and Deaths in Real-Time

    Data visualizations are becoming more and more popular and sometimes they include demographic concepts. The following are two simulations of births and deaths – one for the US and the other for the world.

    Counting Prisoners

    The New York Times had another editorial on this issue:
    Prison-Based Gerrymandering
    Editorial Board | New York Times
    September 26, 2013

    A search on its site shows that this has been a common editorial/story topic

    The PSC Infoblog has had a previous post on this topic as well, which included the Census Bureau’s response to the issue. The Census Bureau released group quarters data in time for redistricting.

    Another excellent source on this topic is the National Academy of Sciences book, which is available in the PSC library:
