Indiana's population sees significant increase

Indiana's population continues to climb.

According to a recent report, Indiana added nearly 39,000 new residents in 2025.

Data analyzed by the Indiana Business Research Center at the Indiana University Kelley School of Business shows the state added exactly 38,579 residents last year, bringing Indiana's total population to 6.97 million. While the growth rate slowed slightly compared to the previous year, the 2025 gains still rank as the state's seventh-largest annual increase over the past two decades.

More than 80% of Indiana's population gains are attributed to people moving into the state rather than natural increase. Notably, net domestic migration more than doubled, jumping from 6,024 people in 2024 to 12,197 in 2025.

For the fourth consecutive year, net international migration remained the largest single source of Indiana’s growth, bringing in a net inflow of 17,852 residents. However, while it is still the state's leading source of growth, this figure represents a 53% decline in international migration compared to 2024.

The population boom is being felt across both urban and rural communities. Central Indiana's Boone and Hancock counties, along with southern Indiana's Clark County, rank as the fastest-growing areas. Meanwhile, Hamilton, Johnson, and Allen counties added the highest total number of new residents. Rural areas are also seeing significant upticks, particularly in Madison, Parke, and Owen counties.
