Population Counts, Estimates and Projections

A region's economy thrives or dives because of the people who choose to live there. That choice may be the happenstance of being born there and desiring to stay, or a more deliberate one of choosing to re-locate from somewhere else.

Monitoring change in the size and movement of population is an important barometer of well-being. Some of us monitor these changes as an insect might gauge the shifting sands, while most don't pay much attention. But the barometer is a good metaphor for population change, since it can presage more notable events, such as lackluster business attraction due to lack of workers.

Daytime Population Estimates

Daytime population refers to the number of people who are present in an area during normal business hours in contrast to the resident population in the evening. In 2000, 70 Hoosier counties have fewer people in them during the day than at night. Marion County has the largest numeric increase due to commuting, while Martin County has the largest percent increase.

More information on the 2007 series of population projections (for 2010-2040) produced by the Indiana Business Research Center, including data, methodology and maps, is available on the Projections Page

Additional Census 2000 Data

Census 2000: A special area to accommodate the most requested population and housing characteristics for counties, cities, townships and census tracts. Detailed profiles are available for each Indiana county, and comparison tables provide 1990 comparisons with ranks and percentages.

Intercensal Estimates

After each census, the Census Bureau revisits the estimates to take into account differences between the postcensal estimates produced during the 1990s and Census 2000 results (Released April 17, 2002).
