Initial Settlement and Population Origins

Peoria started as a French trading post established in the late 17th century. Located along the Illinois River, it soon attracted settlers due to its strategic and fertile location. In 1813, Fort Clark was built, marking the area’s increased prominence.

Throughout the early 1800s, the population grew as European immigrants and settlers from the eastern United States moved in. Agriculture and river trade were primary draws, establishing Peoria as a critical settlement in the region.

Population Trends in the 19th Century

The development of the Illinois River corridor significantly contributed to Peoria’s population boom in the mid-19th century. The Illinois River served as a crucial transportation route, linking Peoria to other major cities and markets.

The completion of the Illinois and Michigan Canal in 1848 further enhanced this connectivity by connecting the Illinois River to Lake Michigan, facilitating easier movement of goods and people between the Mississippi River and the Great Lakes region.

As a result of these improvements in transportation infrastructure, Peoria experienced rapid population growth. According to U.S. Census data, the city’s population increased from approximately 1,619 residents in 1840 to 5,095 in 1850—an impressive growth of over 200% in just a decade.

This trend continued into the next decade, with the population reaching 14,045 by 1860. The accessibility provided by the river corridor attracted industries such as grain processing, distilleries, and manufacturing, which in turn drew workers and their families to the area.

Industrial Growth and Demographic Changes

Peoria’s industrial boom in the late 19th and early 20th centuries marked a significant era of demographic change. The establishment of large industries, such as heavy machinery manufacturing and distilleries, attracted workers from various regions and countries.

According to the U.S. Census Bureau, Peoria’s population grew dramatically during this period.

In 1880, the population was approximately 29,259, and by 1900, it had nearly doubled to 56,100, reflecting the city’s rapid industrialization.

This substantial growth was largely due to the influx of workers seeking employment in the burgeoning industries.

The city’s demographic composition became more diverse as immigrants from countries like Germany, Ireland, and Eastern Europe settled in Peoria. According to historical census data, by 1900, immigrants and their children constituted a significant portion of the population, contributing to the city’s cultural richness.

For instance, the foreign-born population made up about 15% of Peoria’s total population at the time.

The population continued to grow, reaching a peak around the mid-20th century. As reported by the Bureau, Peoria’s population peaked at 111,856 in 1950.

This growth mirrored national trends during the post-World War II era and was fueled by the city’s thriving industrial sector, including major employers like Caterpillar Inc., which established its headquarters in Peoria in 1910.

When examining Peoria’s population changes over a longer period, particularly from 2000 to 2023, it becomes evident that the city has faced periods of both growth and decline. Between 2000 and 2023, Peoria’s population decreased by approximately 2,428 residents according to Neilsberg.

However, this growth was offset by declines in other years, with the most significant decline of 1.3% occurring between 2016 and 2017.

These population shifts reflect broader socioeconomic trends. Economic slowdowns, out-migration, and changes in industrial jobs have played a role in these fluctuations. Despite these declines, the growth in certain years indicates that Peoria can still attract new residents during times of economic stability.

Migration Patterns and Their Impact


The city has seen a net loss of residents due to out-migration, where more people have left the city than have moved in. Between 2000 and 2022, Peoria lost approximately 1,867 residents due to out-migration.

Economic factors such as job opportunities, housing affordability, and quality of life have been key drivers behind the decision of many to leave.

This pattern is not unique to Peoria but reflects broader migration trends in the Midwest, where many cities face challenges in retaining residents.

While Peoria has experienced small population increases in certain years, it has generally faced challenges in maintaining its population. Much of this disparity can be attributed to economic shifts and a lack of job opportunities.
