The Fastest-Growing Cities in America Right Now

State-level population growth gets most of the media attention, but it can obscure what's actually happening at the city level. A slow-growing state can still contain one or two cities growing rapidly, often because growth is concentrated around a specific metro rather than spread evenly across the state.

Percentage growth vs. absolute growth

These tell different stories, and both matter. A small city that grows from 20,000 to 24,000 residents posts a 20% growth rate — a genuinely fast pace — but adds far fewer total residents than a large metro growing by a more modest 3% off a base of a million people. Percentage growth is the better signal for momentum and local strain on infrastructure and housing; absolute growth is the better signal for overall scale of change.

• High percentage growth, smaller base: fast-changing character, often strained local infrastructure.
• Moderate percentage growth, large base: gradual but large-scale absolute change.

What tends to drive rapid city-level growth

Two factors show up consistently in fast-growing cities: available land or zoning that permits new housing construction, and proximity to job growth — either a major employer expansion or spillover demand from a more expensive neighboring metro. Cities that check both boxes tend to see the sharpest population gains; cities with job growth but constrained housing supply tend to see prices rise faster than population.

Growth and housing cost move together — check both

Rapid population growth without a proportional increase in housing supply almost always shows up as accelerating rent and home value growth. Before treating a fast-growing city as an unambiguous opportunity, compare its housing cost trend alongside the population figures — a city growing fast because it's becoming a hot destination and a city growing fast because it still has room to build cheaply are very different situations for someone considering a move.

A note on data timing

Because ACS5 estimates are rolling five-year averages, the most rapid recent growth in a fast-moving city may not be fully reflected in the current release yet — it lags real-time changes by design. For the newest, fastest-growing places, treat the ACS5 figure as a confirmed floor on growth, with the possibility that current, unpublished growth is running even higher.
