Population Time Machine: From 1920 to 2010

AThe always interesting Indiana Business Research Center at the Indiana University Kelley School of Business is celebrating its 90th anniversary this year. As a result, it is releasing information about how the state has changed over that time frame.

A recent release looks at population shifts from 1920 to 2010. The map on the IBRC site provides the visual as 17 counties (many on the western edge of the state) declined in population in that 90-year span; 15 counties experienced at least 200% growth. Here are the lists:

  • Population decline: Benton, Warren, Fountain, Vermillion, Parke, Clay, Sullivan, Greene, Knox, Martin, Pike, Crawford, Tipton, Blackford, Jay, Randolph and Rush
  • At least 200% growth: Lake, Porter, Elkhart, Allen, Tippecanoe, Hamilton, Hendricks, Hancock, Morgan, Johnson, Monroe, Bartholomew, Scott, Clark and Warrick

Marion, Lake, Allen and St. Joseph counties combined for 25% of the state’s population in 1920. That percentage increased to 36% in the 1960s and 1970s before declining to 31% in 2010.

Where Hoosiers Live to Make More Money

Per capita personal income is not created equally across all 92 Indiana counties. It never has been, but a look at the income impacts of the recession provides some interesting disparities.

The credit for the analysis goes to Rachel Justis of the Indiana Business Research Center at the Indiana University Kelley School of Business. Check out her work here.

When per capita income ranges from nearly $49,000 in Boone County to less than $22,000 in LaGrange County, it’s a subject worthy of a closer look. A map provides information for all counties and charts detail those that experienced the greatest change and show a dramatic drop in counties that equal the U.S. per capita figure.

Irish in Indiana

On this St. Patrick’s Day, the Indiana Business Research Center offers a few statistics on Irish roots in the Hoosier State:

  • About 36.3 million U.S. residents claimed Irish ancestry in 2008. This number is more than eight times the population of Ireland (4.4 million). The Irish ancestry is the nation’s second most frequently reported ancestry behind German.
  • Nearly 13 percent of all Hoosiers, 826,456 people, claimed an Irish ancestry in 2008. Massachusetts has the largest share of Irish ancestry (24 percent). The national average is 12 percent.
  • There were 1,937 Irish-born Indiana residents in 2008, which is less than 1 percent of all the population who claimed an Irish ancestry. The majority of these residents entered the United States before 1990 (71.9 percent).

Be sure to celebrate thoroughly and safely.
