Jacksonville vs. Duval County

Jacksonville and Duval County share one consolidated government, but Census figures for Jacksonville city leave out four municipalities inside the county: Atlantic Beach, Baldwin, Jacksonville Beach and Neptune Beach.

The merger itself is settled history. Residents of Jacksonville and Duval County gave consolidation 65 percent of the votes cast in August 1967, and the combined government began on October 1, 1968 (Jacksonville Sheriff's Office history). The City of Jacksonville describes Donna Deegan as the city's ninth mayor since the consolidation of Duval County and the City of Jacksonville governments in 1968, elected alongside a 19-member City Council with 14 district seats and five at-large seats (City of Jacksonville, About Jacksonville).

Four local governments sit inside the county line anyway. The City of Jacksonville's own government directory lists the City of Atlantic Beach, City of Jacksonville Beach, City of Neptune Beach and Town of Baldwin among other officials, apart from the consolidated city's departments (City of Jacksonville, Government). The Census Bureau counts each of them as a separate place, so any statistic labeled Jacksonville city leaves those residents out, while every Duval County figure includes them.

Census tables count the Beaches and Baldwin apart from Jacksonville because each of the four still has a municipal government of its own inside Duval County (City of Jacksonville government directory).

The practical result shows up in every data table. A resident of Neptune Beach or Baldwin lives in Duval County, whose county government is the consolidated City of Jacksonville, but is counted by the Census Bureau in a separate city or town. That is why the Jacksonville city and Duval County totals in the tables below differ by tens of thousands of people even though both describe the same consolidated government on paper.

Jacksonville city held 977,670 residents and Duval County 1,023,153 in the Census Bureau's ACS 2020-2024 estimates, so the city is about 96 percent of the county.

The gap of 45,483 people equals, exactly, the combined ACS populations of Jacksonville Beach, Atlantic Beach, Neptune Beach and Baldwin shown further down, and the household gap of 20,758 matches their combined households the same way (DP05, Jacksonville city; DP05, Duval County; DP02, Jacksonville city; DP02, Duval County). Because the city is so large a share, the Jacksonville and Duval County figures track each other closely.

Income, home value and poverty come from the DP03 and DP04 profiles (DP03, Jacksonville city; DP03, Duval County; DP04, Jacksonville city; DP04, Duval County). Adding the four smaller municipalities nudges the Duval County figures up on income, home value and degrees and down on poverty, which fits the Beaches profiles below. Land area barely differs: 747.266 square miles for Jacksonville city and 762.623 for Duval County in the 2024 gazetteers (2024 Gazetteer, Florida places; 2024 Gazetteer, Florida counties).

Jacksonville city grew from 821,784 in the 2010 Census to 949,611 in 2020, and the Census Bureau estimates 1,017,689 for July 1, 2025.

Duval County went from 864,263 to 995,567 between the same two censuses (Census 2010, Jacksonville city; Census 2020, Jacksonville city; Census 2010, Duval County; Census 2020, Duval County). In the Vintage 2025 estimates, Jacksonville city rose from an April 2020 base of 949,607 to 1,017,689 on July 1, 2025, about 7.2 percent (Vintage 2025 subcounty estimates; columns per the file layout), while Duval County reached 1,062,963 (Vintage 2025 county estimates).

Official sources do not agree on a single current number. The City of Jacksonville's economic development page cites approximately 1,007,189 residents (City of Jacksonville), which is below the Census Bureau's July 2025 estimate of 1,017,689 and above its ACS 2020-2024 average of 977,670. The three figures measure different things: a city figure of unstated date, a single-day estimate and a five-year survey average.

The three Beaches cities are small, older and much wealthier than Jacksonville city, with median household incomes near $120,000 against $69,872.

All figures below are ACS 2020-2024 five-year estimates, the same release used for Jacksonville city, so they compare directly (DP05, Jacksonville Beach; DP05, Atlantic Beach; DP05, Neptune Beach; DP03, Jacksonville Beach; DP03, Atlantic Beach; DP03, Neptune Beach; DP04, Jacksonville Beach; DP04, Atlantic Beach; DP04, Neptune Beach).

Land areas come from the 2024 Florida place gazetteer (Census Gazetteer). Side by side with Jacksonville city, the Beaches run about 7 to 12 years older in median age and their median home values are roughly twice the city's $293,700. Degrees follow the same line: 59.5 percent of Jacksonville Beach adults 25 and older hold a bachelor's degree or higher, against 33.2 percent in Jacksonville city (DP02, Jacksonville Beach).

The Census Bureau's estimates also show the Beaches holding roughly steady while the consolidated city grows. Jacksonville Beach went from an April 2020 base of 23,833 to 23,615 in July 2025, Atlantic Beach from 13,511 to 13,245 and Neptune Beach from 7,208 to 7,020 (Vintage 2025 subcounty estimates). Over the same period Jacksonville city added about 68,000 people.

Baldwin is the smallest and lowest-income of the four, a town of 1,298 people with a median household income of $47,500 in ACS 2020-2024.

The Census Bureau lists Baldwin town at 2.021 square miles of land, with an internal point at longitude 81.97 west, well west of the internal point for Jacksonville city at 81.66 west (2024 Gazetteer, Florida places). Its median home value is $180,700 and 16.3 percent of residents live below the poverty level (DP04, Baldwin; DP03, Baldwin), and its median age is 41.3 (DP05, Baldwin). Margins of error are wide for a town this size, so the figures are best read as rough levels.

In countywide totals Baldwin barely registers, about one Duval County resident in 790, and its estimated population was 1,394 on July 1, 2025, against an April 2020 base of 1,410 (Vintage 2025 subcounty estimates). It is still the reason a Duval County figure never equals the Beaches plus Jacksonville city.

Last verified: October 18, 2026, by pulling fresh ACS 2020-2024 profiles for Jacksonville city, Duval County and its four other municipalities, the 2010 and 2020 census counts, the Vintage 2025 Census estimates and 2024 gazetteers, and by rereading the City of Jacksonville about and government directory pages and the Jacksonville Sheriff's Office history.
