An analysis by the Indiana Business Research Center at the Indiana University Kelley School of Business shows that population is steadily growing in the state.
“Since 2023, Indiana has had an average annual growth of more than 43,900 residents per year, which is the state’s largest increase over a three-year stretch since adding roughly 48,700 residents a year from 2006 to 2008,” said Matt Kinghorn, senior demographer at the Indiana Business Research Center, in a press release.
Michiana is doing its part with modest increases per county. Two of the largest counties in the state both reported increases between 2020 and 2025.
The Kelley School of Business analysis notes that natural increases (births and deaths) accounted for 70% of the state's population growth between 2006 and 2008, but during the past three years, migration accounts for 81% of the state's increases.
“This marks the first time in the last four years that Indiana’s natural increase has declined, which suggests that the state’s post-pandemic rebound in natural increase may have peaked in 2024,” Kinghorn said.
Michiana counties' estimated growth rates between July 1, 2020, and July 1, 2025, mostly increased, according to STATS Indiana.
