In Illinois, one suburb stands out as the fastest-growing and most dynamic community—so much so that it’s been officially crowned the biggest boomtown in the state. But here’s where it gets interesting: this isn’t just about raw numbers; it’s about the story of a community rapidly transforming and attracting new residents at an astonishing rate.
A recent analysis by a financial news platform took a close look at cities across the United States that have populations ranging from 25,000 to half a million residents. Using data from the U.S. Census Bureau, comparing figures from 2015 and 2023, they identified which communities have experienced the most significant population surges and economic growth over the past eight years. The approach involved calculating both how much the population has increased and how per capita income has changed, offering a more comprehensive picture of community vitality.
In Illinois, that top spot belongs to Plainfield, a suburb located in the southwestern part of the Chicago metropolitan area, straddling Kendall and Will counties. As of the 2020 Census, it was home to 44,762 residents, but by 2023, that number had grown to approximately 45,705. This means Plainfield’s population increased by nearly 12% since 2015—a remarkable growth rate.
Beyond just counting heads, the data also highlights economic progress. The average income per person in Plainfield surged by over 43% during this period, reaching around $53,675 in 2023. Such rapid economic development often goes hand-in-hand with demographic shifts, signaling a community that’s not only attracting new residents but also improving its overall quality of life.
To put this into perspective, while Plainfield is experiencing a notable boom within Illinois, it doesn’t hold the national record for growth. That distinction goes to Fulshear, Texas, a small city just outside Houston, which has seen its population explode by an incredible 736% over the same eight-year span. With approximately 40,000 residents today, Fulshear’s rapid expansion exemplifies how some communities are transforming at a pace that defies expectations.
This raises some compelling questions about what factors fuel such explosive growth—be it affordability, job opportunities, quality of life, or other influences—and whether these trends will continue or slow down in the coming years. Do you think communities like Plainfield or Fulshear can sustain this momentum? Or are such rapid changes inevitably followed by challenges? Share your thoughts—this is a conversation worth having.
