The metropolitan Indianapolis area is expected to continue to experience solid growth rates for the next 3 decades.

In 1970, Hamilton County had 55,000 citizens and ranked 21st of Indiana’s 92 counties. It doubled in size to 110,000 by 1990, ranking 11th largest and joining Madison, Delaware, Tippecanoe, Vigo and LaPorte as “major” counties. By 2000 Hamilton County contained 185,000 people and was ranked the 6th largest in Indiana. Hamilton continued to grow by 75,000 per decade, passing Elkhart and St. Joseph counties for 4th place by 2010. Based on these trends, Hamilton will pass Allen County by 2030 and Lake County by 2040 to become the second largest Indiana county, trailing only Marion County.

Hamilton County has grown as part of the Indy Metro area. Marion County has averaged growth of 60,000 people in the last 3 decades. Hamilton County is forecast to maintain its 73,000 per decade growth rate. The other four suburban counties are forecast to maintain their combined 80,000 per decade growth rate.

Summary

Hamilton County has enjoyed annual population growth of 7-8,000 for the last 30 years and can reasonably be forecast to continue such growth for the next 30 years. The growth of the Indy Metro area stands out versus slower growing areas in Indiana and the Midwest. Hamilton County’s four major cities continue to attract new residents and the county’s northern areas remain available for managed development within short commuting distances of the existing economic centers throughout the county. Economic growth has a tendency to be self-reinforcing. As Hamilton County approaches one-half million residents it will focus more on “managing” such growth.
