Port St. Lucie growth is drawing national attention as the city rapidly expands, sparking comparisons with Miami regarding population trends and future projections. Despite claims that Port St. Lucie could soon overtake Miami in population, current data and expert forecasts indicate this is unlikely to occur within the next few years.
Port St. Lucie Growth Outpaces Miami
Port St. Lucie is recognized as one of Florida‘s fastest-growing cities, consistently ranking among the top five fastest-growing metropolitan areas in the United States. According to recent census data, the city’s annual growth rate is significantly higher than Miami’s, fueling speculation about whether Port St. Lucie could surpass Miami in population size. This surge is partly due to the fact that Port St. Lucie attracts homebuyers from major metros amid market shifts, making it a prime destination for those seeking new opportunities.
Current Population Figures
As of 2025, Port St. Lucie has an estimated population of 270,491, while Miami stands at approximately 464,655 residents. The difference remains substantial, with Miami maintaining a lead of nearly 200,000 people.
Annual Growth Rates
- Port St. Lucie: 4.94% annual growth rate
- Miami: 0.95% annual growth rate
This means Port St. Lucie is growing about five times faster than Miami, a trend that has persisted for several years.
Comparing City Size and Density
One factor contributing to Port St. Lucie’s rapid growth is its available land area. The city covers 119 square miles, compared to Miami’s 36 square miles. This gives Port St. Lucie three times more space for new housing, businesses, and infrastructure. The influx of new residents is also being supported by a boom in apartment construction, with Port St. Lucie leading the U.S. in new apartment construction growth to accommodate the city’s expanding population.
Population Density Differences
- Port St. Lucie: 1,718 people per square mile
- Miami: 12,286 people per square mile
Miami remains much more densely populated, with seven times the number of residents per square mile compared to Port St. Lucie.
Port St. Lucie vs Miami: Metro Area Comparison
While city population is important, metro area figures provide broader context. The Miami metro area has an estimated population of 6,317,000, making it over ten times larger than the Port St. Lucie metro area, which is home to about 574,000 residents.
Metro Area Growth Patterns
- Miami Metro: Remains a major economic and cultural hub
- Port St. Lucie Metro: Experiencing strong growth, but the gap with Miami is not expected to close this century
Despite Port St. Lucie’s impressive growth rate, the size of Miami’s metro area ensures its continued dominance in population and economic influence.
Population Projections Through 2040
Projections based on current trends suggest that Port St. Lucie will continue to grow at a rapid pace, but overtaking Miami in city population is unlikely before 2035–2040, if at all.
Forecasted Populations
- Port St. Lucie (2030): ~267,112 residents
- Port St. Lucie (2035): ~306,372 residents
- Miami (2030): ~457,785 residents
- Miami (2035): ~465,898 residents
Even with a higher growth rate, Port St. Lucie is not projected to surpass Miami in population within the next decade. The gap could narrow by 2035–2040, but only if Miami’s growth slows significantly.
National Rankings and Economic Impact
Port St. Lucie’s rapid expansion has earned it a place among the nation’s fastest-growing metro areas. According to 2022–2023 census data, it consistently ranks in the top five for growth rate. Miami, meanwhile, continues to serve as a major national and international hub, with a much larger economic base and established infrastructure.
Strategic Location Advantages
- Port St. Lucie: Located 110 miles from both Miami and Orlando, making it a strategic logistics hub
- Miami: Gateway to Latin America and a global business center
Port St. Lucie’s location supports its growth as a residential and commercial destination, but Miami’s established status ensures its ongoing prominence. In recent years, many people have chosen to relocate from the Northeast, especially New York, to Florida—reflecting a broader trend of migration that is reshaping the region.

Fact-Checking the Google AI Claim
Recent claims, including those attributed to Google AI, have suggested that Port St. Lucie could surpass Miami in population within the next few years. However, a review of official census data and credible forecasts shows this is not supported by current trends.
While Port St. Lucie is growing quickly, the population gap between the two cities remains significant. Even with sustained high growth, Port St. Lucie is not expected to overtake Miami before 2035–2040, and Miami’s metro area will remain vastly larger for the foreseeable future.
