Demographics of St. Petersburg, Florida

According to the U.S. Census Bureau American Community Survey (ACS) 2023, St. Petersburg has a total population of 260,646, establishing it as the most populous city in Pinellas County — which the U.S. Census Bureau identifies as Florida's most densely populated county. The city's median age of 43.1 years situates it near the Florida median, reflecting a population that skews somewhat older than the national average. The four figures below summarize the city's demographic and economic profile at a glance.

The median household income of $73,118 and median home value of $331,500 place St. Petersburg within a moderate-to-elevated range relative to Florida norms. A poverty rate of 11.7 percent and an unemployment rate of 4.9 percent, both drawn from the ACS 2023, round out the economic baseline. These headline figures are explored in greater depth in the sections that follow.

St. Petersburg's population of 260,646, as measured by the U.S. Census Bureau ACS 2023, makes it the anchor city of the Pinellas Peninsula and a primary population center within the Tampa–St. Petersburg–Clearwater metropolitan statistical area. The city's population is distributed across 116,772 occupied households, which implies an average of roughly 2.23 persons per household — a figure consistent with a mix of family and non-family living arrangements typical of mid-size Sunbelt cities.

The median age of 43.1 years reflects a population that is older than the United States median but broadly consistent with Florida's pattern of attracting retirees and older working adults. Florida as a whole carries a median age of approximately 42.6 years, itself elevated above the national median of roughly 38.9 years, and St. Petersburg sits just above the state figure. The city's position on a water-flanked peninsula with a temperate climate has historically attracted older residents, though the growth of a healthcare and technology employment base has also brought working-age residents into the population mix.

The historical context for St. Petersburg's population is significant: the city was incorporated as a town on February 29, 1892, with approximately 300 residents, according to the City of St. Petersburg's history page. The arrival of the Orange Belt Railway terminus in 1888, co-engineered by Peter Demens, catalyzed the settlement's growth. From those origins, the city grew into a metropolitan anchor of more than a quarter-million residents over the following 130 years.

The median household income in St. Petersburg stands at $73,118, according to the U.S. Census Bureau ACS 2023. This figure places the city modestly above the Florida median household income of approximately $67,000 and below the U.S. median of roughly $77,700, positioning St. Petersburg within the middle tier of Florida's major cities by income. The income figure captures all household types — families, non-family households, and single-person households alike — and reflects the earnings environment across the city's diverse residential and employment base.

The poverty rate of 11.7 percent indicates that a meaningful share of St. Petersburg's population falls below the federal poverty threshold. This rate is above the national poverty rate of approximately 11.1 percent and reflects persistent income disparities that have been a documented feature of the city's civic conversation. The City of St. Petersburg's approved redevelopment agreement for the Historic Gas Plant District includes a $50 million commitment to equity initiatives in South St. Petersburg, encompassing affordable housing funding, employment support, and minority- and women-owned business hiring goals, as documented on the City of St. Petersburg's news page.

Income conditions are also reflected in the city's housing cost burden environment. With a median gross rent of $1,542 per month and a median household income of $73,118, a renter at the median income level would allocate approximately 25 percent of gross income to rent — near the conventional affordability threshold — though households earning below the median face proportionally greater cost burdens. Mayor Ken Welch's 2026 State of the City address, published on the City's website, highlighted the completion of 434 multifamily affordable and workforce units in 2025, alongside 122 accessory dwelling units and 24 affordable homes, as part of the city's documented response to affordability pressures.

St. Petersburg's housing stock totals 141,039 units as of the ACS 2023, of which 116,772 are occupied households. The difference — approximately 24,267 units — comprises vacant units, seasonal homes, and properties not in year-round residential use, a pattern common in coastal Florida cities where second-home and seasonal occupancy represents a non-trivial share of the housing inventory. The occupied housing stock is split 63 percent owner-occupied and 37 percent renter-occupied, indicating a moderately owner-dominant tenure structure.

The median home value of $331,500 situates St. Petersburg above the Florida statewide median of approximately $305,000 and well above the national median of roughly $244,900. This premium reflects the city's coastal location, its position within a large metropolitan area, and post-pandemic appreciation in the Tampa Bay market. The median gross rent of $1,542 per month similarly exceeds the Florida median of approximately $1,450, continuing a pattern of above-average rental costs in the region.

The affordability challenge is documented in the city's own policy actions. Following Hurricanes Helene and Milton in 2024, which the City of St. Petersburg reports generated 2.1 million cubic yards of debris — the largest volume ever collected by the city — housing recovery became an acute concern. Pinellas County received $813,783,000 in U.S. Department of Housing and Urban Development Community Development Block Grant Disaster Recovery funds for storm recovery, as reported by WUSF Public Media, a significant infusion directed in part toward housing reconstruction and mitigation.

St. Petersburg's labor force participation rate stands at 72.8 percent, according to the U.S. Census Bureau ACS 2023, meaning nearly three in four residents of working age are either employed or actively seeking employment. This rate falls slightly below the U.S. labor force participation rate of approximately 63 percent for the total civilian population aged 16 and over — though methodological differences in how the ACS reports this figure mean direct comparisons require care. The unemployment rate of 4.9 percent, measured against the labor force, is modestly above the national rate prevailing during the 2023 survey period.

The city's employment base spans healthcare, financial services, and an expanding technology sector, as documented in the research brief. Johns Hopkins All Children's Hospital, located in downtown St. Petersburg, is a major institutional employer. The hospital was ranked Florida's No. 1 children's hospital for the third consecutive year in the U.S. News and World Report 2025–26 Best Children's Hospitals rankings and tied for No. 4 in the Southeast, as reported by Tampa Bay Business & Wealth. Healthcare employment of this scale creates a broad downstream labor demand across nursing, administration, research, and support services.

Tourism and cultural institutions constitute a distinct employment sector. The Salvador Dalí Museum holds more than 2,400 works, including nearly 300 oil paintings, watercolors, and drawings, as stated on the museum's website, and anchors a downtown arts district that includes the Museum of Fine Arts, the Chihuly Collection, and the James Museum of Western & Wildlife Art. The broader tourism economy, including Fort De Soto Park which attracts more than 2.7 million visitors annually, generates hospitality and service-sector employment across the city. The redevelopment of the Historic Gas Plant District, with infrastructure construction beginning in 2025 and first-phase openings targeted for late 2027 or early 2028 per the City of St. Petersburg, is expected to add additional construction and eventual permanent employment in the years ahead.

Among St. Petersburg residents aged 25 and older, 26.1 percent hold a bachelor's degree or higher, according to the U.S. Census Bureau ACS 2023. This figure falls below both the Florida statewide rate of approximately 32.0 percent and the U.S. rate of roughly 35.5 percent, placing St. Petersburg in the lower-middle tier of Florida's major cities by bachelor's degree attainment. The gap relative to state and national benchmarks is notable given the city's large institutional employment base in healthcare and finance, sectors that typically draw degree-holders.

Educational attainment patterns in a city like St. Petersburg reflect a layered population structure: long-established working-class and lower-income neighborhoods — particularly in South St. Petersburg — carry lower educational attainment rates that pull the citywide average downward, while newer arrivals drawn to the technology and healthcare sectors may carry higher degree rates. The ACS does not disaggregate attainment at the neighborhood level in the data provided here, so the 26.1 percent figure represents a citywide composite rather than a picture of any one community.

The 11.7 percent poverty rate, read alongside the 26.1 percent bachelor's attainment figure, suggests that a substantial segment of the resident population faces both income and credential barriers in the labor market. The City of St. Petersburg's redevelopment commitments — including employment support and workforce development components embedded in the Historic Gas Plant District agreement, as documented on the City's news page — represent a formally documented policy response to these structural conditions.

All headline demographic and economic figures cited throughout this page — including total population, median age, housing units, occupied households, owner- and renter-occupancy rates, median gross rent, median home value, median household income, poverty rate, unemployment rate, labor force participation, and educational attainment — are drawn from the U.S. Census Bureau American Community Survey (ACS) 5-Year Estimates, 2023. ACS 5-year estimates pool data across five calendar years to produce statistically reliable figures for geographies of all sizes; they represent period estimates rather than point-in-time counts. As such, they differ methodologically from the decennial Census and may diverge from single-year estimates where those are available for large cities.

Comparative figures for Florida and the United States (used in comparison rows throughout this page) are drawn from general knowledge of ACS 2023 state and national medians and are marked with a tilde (~) to indicate approximation. These comparators are provided for contextual orientation only; readers requiring precise state or national figures should consult the Census Bureau's data explorer directly.
