Overview
Oklahoma County is the most populous county in Oklahoma, home to 800,487 residents (Census ACS 5-Year, 2023). That places it above 98% of all U.S. counties by population. It contains Oklahoma City, the state capital, and sits in the central part of the state.
The county's median household income of $65,374 (Census ACS 5-Year, 2023) falls near the middle nationally, ranking higher than 56% of U.S. counties. Per capita income runs higher at $38,438 (Census ACS 5-Year, 2023), above 73% of counties nationwide. The median age here is 35.1 years (Census ACS 5-Year, 2023), younger than more than 90% of U.S. counties.
What stands out in the data: a young, diverse population with relatively affordable housing, paired with education spending that ranks among the lowest in the country. The county also sits in one of the most disaster-prone zones in the nation, with 51 FEMA-declared disasters on record (FEMA OpenFEMA, 2026).
Demographics
At 35.1 years, the median age (Census ACS 5-Year, 2023) is lower than roughly 91% of U.S. counties. Within Oklahoma, only a handful of counties skew younger. A young population of this size puts pressure on schools, entry-level job markets, and housing stock in ways that older, smaller counties don't experience.
The county is notably diverse. White residents make up 52.9% of the population (Census ACS 5-Year, 2023), lower than 85% of U.S. counties. Hispanic residents account for 19.6%, higher than 86% of counties nationally. Black residents represent 14.2%, above 80% of U.S. counties. Asian residents make up 3.4%, higher than 91% of counties. Native American residents account for 2.3% (Census ACS 5-Year, 2023), which, despite being in Oklahoma, ranks at just the 18th state-level ranking, reflecting that many rural Oklahoma counties have higher Native populations.
Educational attainment is strong. About 35.1% of adults hold a bachelor's degree or higher (Census ACS 5-Year, 2023), above 86% of U.S. counties and ranking in the top 4% within Oklahoma. That's the profile of a county anchored by state government, universities, and a white-collar employment base.
Education
Per-pupil spending in Oklahoma County is $9,937 (Education Data Portal, 2020). The national average sits around $15,000. That puts the county's spending lower than 98% of U.S. counties and in the bottom 3% within Oklahoma. This is a significant gap, not a rounding error.
Total enrollment reaches 181,354 students (Education Data Portal, 2021), higher than 99% of counties nationally, consistent with the county's population size. The student-teacher ratio is 17.9:1 (Education Data Portal, 2021), above the national average of roughly 15.5:1 and higher than 91% of U.S. counties. Within Oklahoma, it's the highest in the state.
The graduation rate is 72.6% (Education Data Portal, 2019), compared to a national average near 87%. That's lower than 96% of U.S. counties and in the bottom 3% within the state. Combined with the low per-pupil spending, the numbers paint a consistent picture: large class sizes, less money per student, and outcomes that fall well short of national norms. For a county with above-average educational attainment among adults, the K-12 pipeline tells a different story. That gap between adult degree-holding and student graduation suggests the college-educated population is partly drawn from elsewhere rather than produced locally.
Economy & Employment
The labor force totals 423,730 people (BLS LAUS, 2025), with 407,776 employed and 15,954 unemployed. The unemployment rate of 3.8% (BLS LAUS, 2025) sits right at the national midpoint, ranking higher than 51% of U.S. counties. It's a stable number, neither concerning nor exceptional.
Median household income of $65,374 (Census ACS 5-Year, 2023) ranks higher than 56% of counties nationally and in the top 18% within Oklahoma. Per capita income reaches $38,438 (Census ACS 5-Year, 2023), a stronger showing at the 73rd national ranking and 92nd within the state. The gap between household and per capita rankings suggests smaller household sizes or more single-earner households compared to places where household income ranks higher.
IRS data offers another angle. The average adjusted gross income was $79,067, and average total income was $79,702 (IRS Statistics of Income, 2021), drawn from 357,060 tax returns. Both figures rank above 82% of U.S. counties. The IRS numbers run higher than the Census median because they capture the full income distribution, including high earners who pull the average up.
The poverty rate is 15.4% (Census ACS 5-Year, 2023). That's higher than 67% of U.S. counties, meaning roughly two-thirds of counties have lower poverty. Within Oklahoma, the county falls near the middle of the pack at the 43rd state ranking. For a county with strong per capita income and a large professional workforce, a 15.4% poverty rate indicates real economic stratification. The averages mask a wide spread.
Mean commute time is 19.8 minutes (Census ACS 5-Year, 2023), shorter than 70% of U.S. counties. As the county containing the state capital and its largest city, most workers can reach jobs without long drives, a practical advantage that keeps transportation costs down.
Housing & Cost of Living
Median home value in Oklahoma County is $207,800 (Census ACS 5-Year, 2023), above 64% of U.S. counties and 88th within Oklahoma. The median gross rent is $1,073 (Census ACS 5-Year, 2023), higher than 78% of counties nationally and the highest-ranking in the state at the 96th position.
Total housing units number 356,997 (Census ACS 5-Year, 2023), with 33,895 vacant, producing a vacancy rate of 9.5% (Census ACS 5-Year, 2023). That vacancy rate is lower than 75% of U.S. counties and in the bottom 9% within the state. A tighter housing market with limited vacancies, combined with rents that top nearly every other Oklahoma county, suggests that housing supply isn't keeping pace with demand.
Fair market rent data from HUD (HUD Fair Market Rents, 2026) is available for Oklahoma County but specific bedroom-level breakdowns aren't included in the current dataset.
The ratio of home value to income offers a rough affordability check. At $207,800 median home value against $65,374 median household income, the price-to-income ratio is about 3.2x. That's moderate by national standards but on the higher end for Oklahoma. Renters face a different calculation: $1,073 monthly rent against $65,374 annual income works out to roughly 20% of gross income, which falls within typical affordability thresholds. But the 15.4% poverty rate means a sizable portion of the population pays a much larger share.
Health & Wellness
The obesity rate in Oklahoma County is 37.9% (CDC PLACES, 2023), right near the national midpoint at the 46th ranking. High blood pressure affects 35.9% of adults (CDC PLACES, 2023), above 72% of U.S. counties but only at the 27th ranking within Oklahoma, where rates tend to run high.
Mental health indicators deserve attention. Depression affects 25.1% of adults (CDC PLACES, 2023), higher than 61% of U.S. counties. Poor mental health days affect 17.7% (CDC PLACES, 2023), which, while ranking at the 30th national level, places the county in the bottom 9% within Oklahoma. The state-level comparison matters more here because it shows Oklahoma County fares better than most of the state on mental health, even if the absolute numbers aren't low.
Poor physical health days affect 13.0% of adults (CDC PLACES, 2023), ranking lower than 64% of counties nationally and in the bottom 8% within the state. Again, better than most of Oklahoma but below the national median.
Diabetes prevalence is 12.0% (CDC PLACES, 2023), above 69% of U.S. counties. Cholesterol screening reaches 84.1% (CDC PLACES, 2023), a strong preventive-care number that ranks above 71% of counties nationally and 90th within the state.
The uninsured rate is 12.6% (CDC PLACES, 2023), higher than 69% of U.S. counties. Oklahoma hasn't expanded Medicaid for as long as many other states, and the uninsured rate reflects that policy environment. Annual checkup rates reach 77.6% (CDC PLACES, 2023), above 77% of counties nationally.
The pattern across health metrics: Oklahoma County performs better than most of the state but worse than national norms on chronic conditions and insurance coverage.
Climate & Natural Disasters
Oklahoma County has 51 federal disaster declarations on record (FEMA OpenFEMA, 2026), the highest unique disaster count of any county in the country (above 100% of U.S. counties). That's a function of geography as much as anything else. The county sits in Tornado Alley, gets the full range of Great Plains weather, and as Oklahoma's most populous county, it shows up on nearly every major state disaster.
The climate's warm. Average annual temperature is 62.4°F, warmer than 78% of U.S. counties, with typical highs of 73.3°F and lows of 51.5°F (NOAA Climate Data Online, 2025). Annual precipitation is 43.4 inches (above 65% of U.S. counties), and snowfall is modest at 4.8 inches per year (above only 23% of counties).
Severe storms and ice storms make up the bulk of the disaster record. Ten severe storm declarations and six severe ice storm declarations appear in FEMA's history here. Ice events hit in consecutive winters around 2000-2002, returned in 2007, and the February 2021 storm triggered both an emergency declaration and a major disaster declaration within days (FEMA, 2021). Wildfire is the other recurring hazard, with fire management declarations running nearly continuously through 2011 and returning in 2023 and May 2025 (FEMA, 2025).
Two tornado declarations stand apart. The May 1999 outbreak produced one of the strongest tornadoes ever recorded (FEMA, 1999). The 2013 declaration followed the Moore EF5, which struck the county's southern communities directly (FEMA, 2013).
With a disaster declaration as recent as May 2025, this history's still accumulating. Storm seasons will keep arriving, fire risk rises in dry years, and the ice storm record suggests those winters come around more often than residents might expect.
Financial Profile
IRS data from 2021 shows 357,060 tax returns filed in Oklahoma County, with total adjusted gross income of $28.2 billion and total income of $28.5 billion (IRS Statistics of Income, 2021). Both figures rank above 96% of U.S. counties, reflecting the county's large population and concentration of professional employment. The average AGI of $79,067 and average income of $79,702 (IRS Statistics of Income, 2021) rank above 82% of counties nationally and 95th within Oklahoma.
Banking access is extensive. The county has 389 bank branches holding $46.8 billion in total deposits (FDIC Summary of Deposits, 2023). Branch count ranks above 99% of U.S. counties. The deposit base, also above 98% nationally, signals a major financial center for the state.
Social Security beneficiaries total 146,005 (SSA OASDI, 2024), above 98% of U.S. counties. With a total population of about 800,000, that means roughly 18% of residents receive Social Security benefits, a relatively low ratio consistent with the county's young median age. In older counties, this share can exceed 30%.
Key Comparisons
Oklahoma County occupies an unusual position in the data. It's the largest county in its state by nearly every measure (population, labor force, enrollment, tax returns, bank branches, deposits) while showing middling-to-moderate results on per-person metrics.
Income tells a split story. Median household income ($65,374) ranks near the national median, but per capita income ($38,438) and average AGI ($79,067) rank considerably higher. The poverty rate of 15.4% runs above two-thirds of U.S. counties. Wealth and poverty coexist in close proximity.
Education shows the widest gap between inputs and outcomes. Adult degree-holding (35.1%) ranks in the top 14% nationally, yet graduation rates (72.6%) fall in the bottom 4% and per-pupil spending ($9,937) in the bottom 2%. The adults who live here are well-educated; the school system producing the next generation is underfunded by national standards.
Health metrics consistently place the county better than most of Oklahoma but below national medians on chronic conditions. The 12.6% uninsured rate reflects state-level policy choices more than county-level factors.
Housing remains relatively affordable compared to national figures, with a price-to-income ratio around 3.2x, but the low vacancy rate (9.5%) and high rents relative to the rest of Oklahoma suggest tightening conditions.
The disaster count (51) is among the highest of any U.S. county, a persistent risk factor for infrastructure, insurance costs, and long-term planning.
