Overview
Shelby County is home to 922,195 people (Census ACS 5-Year, 2023), making it the largest county in Tennessee by population, ranking higher than 99% of counties in the state and 98% of all U.S. counties. The county seat is Memphis, the state's biggest city and a major economic hub on the Mississippi River.
A median age of 35.8 years (Census ACS 5-Year, 2023) puts Shelby County younger than roughly 90% of U.S. counties. That's a full three years below the national median of about 38.5. The workforce is large, with a labor force of 433,161 (BLS LAUS, 2025), and the county holds 403,144 housing units (Census ACS 5-Year, 2023). With 28 federal disaster declarations on record (FEMA OpenFEMA, 2026) and a poverty rate of 17.2% (Census ACS 5-Year, 2023) that sits above most of the country, Shelby County carries the weight and complexity that come with being a major urban center in the mid-South.
Demographics
Shelby County's population is majority Black, at 52.6% (Census ACS 5-Year, 2023), placing it higher than 98% of U.S. counties and 99% of Tennessee counties on that measure. White residents make up 33.3%, Hispanic residents 8.5%, and Asian residents 2.8% (Census ACS 5-Year, 2023). The Asian population share ranks above 88% of counties nationally, reflecting a more diverse composition than most of the state.
At 35.8 years, the median age (Census ACS 5-Year, 2023) is among the lowest in Tennessee, lower than 96% of the state's counties. Young populations tend to correlate with larger labor forces and higher demand for schools, childcare, and entry-level housing.
Education attainment is a relative strength. About 34.2% of adults hold a bachelor's degree or higher (Census ACS 5-Year, 2023), ranking above 85% of U.S. counties and 93% of Tennessee counties. That rate is close to the national average of around 33%, which is notable for a county where poverty also runs well above the national rate. The gap between the educated and the economically stable tells part of Shelby County's story.
Education
Shelby County Schools enrolled 144,030 students (Education Data Portal, 2021), a figure higher than 98% of U.S. counties and 99% within Tennessee. It's one of the largest school districts in the country by enrollment.
Per-pupil spending was $12,462 (Education Data Portal, 2020), sitting below the national average of roughly $15,000 and lower than about 77% of U.S. counties. Within Tennessee, though, it ranks above 85% of counties, suggesting the state as a whole spends less per student than much of the country.
The student-teacher ratio stands at 15.7:1 (Education Data Portal, 2021), close to the national average of 15.5:1 and higher than 76% of U.S. counties. More students per teacher generally means larger class sizes.
The graduation rate is where the numbers get harder. At 79.2% (Education Data Portal, 2019), Shelby County falls well below the national average of about 87%. It ranks lower than 85% of U.S. counties and lower than 99% of Tennessee counties. Only one county in the state posted a lower rate. Graduation is the single metric where Shelby County falls furthest behind, and for a county with above-average college attainment among adults, the contrast with K-12 outcomes is sharp.
Economy & Employment
Median household income in Shelby County was $62,337 (Census ACS 5-Year, 2023). That's below the national median of about $75,149 and sits around the 46th national ranking, meaning more than half of U.S. counties report higher household incomes. Within Tennessee, it ranks above 72% of counties, which reflects more on the state's generally lower income levels than on Shelby County's strength.
Per capita income tells a slightly different story at $37,666 (Census ACS 5-Year, 2023), ranking higher than 70% of U.S. counties and 88% within Tennessee. The gap between per capita and household income suggests a mix of high earners and lower-income households pulling the median down.
The unemployment rate was 4.3% (BLS LAUS, 2025), with 18,655 residents out of work against a labor force of 433,161. That rate sits higher than 65% of U.S. counties and 84% of Tennessee counties. It's not extreme, but it's above average on both scales.
Poverty is the harder number. At 17.2% (Census ACS 5-Year, 2023), Shelby County's poverty rate is higher than 77% of U.S. counties and 72% of Tennessee counties. Roughly one in six residents lives below the poverty line. Combined with a below-average median household income and an above-average unemployment rate, the economic picture is mixed. The county generates significant wealth (total adjusted gross income of $34.1 billion from 435,870 tax returns, per IRS Statistics of Income, 2021), but that wealth isn't evenly distributed.
Average AGI per return was $78,346 (IRS Statistics of Income, 2021), ranking above 81% of U.S. counties. Average total income was $79,201 (IRS Statistics of Income, 2021). The spread between average and median income confirms that higher earners pull the averages up while the median household sits well below the national figure.
Housing & Cost of Living
The median home value in Shelby County was $229,700 (Census ACS 5-Year, 2023), above 71% of U.S. counties and 75% of Tennessee counties. That's lower than the national median of roughly $280,000, which makes housing relatively more accessible compared to many metro areas.
Median gross rent was $1,170 per month (Census ACS 5-Year, 2023), ranking higher than 84% of U.S. counties and 88% within Tennessee. Renters here pay more than most of the country, though the figure is still below the costliest urban markets.
The county holds 403,144 total housing units, with 42,554 sitting vacant (Census ACS 5-Year, 2023). That's a vacancy rate of 10.6%, which falls in the lower third nationally (higher than only 30% of U.S. counties) but sits at the 34th state ranking. A vacancy rate around 10% in a large urban county often reflects a mix of turnover, distressed properties, and ongoing development rather than a shortage or a surplus.
Fair market rent data from HUD (2026) is available for the county but specific bedroom-level values were not returned in this dataset.
Health & Wellness
Shelby County's health data shows a population with high engagement in preventive care and elevated rates of chronic conditions.
On the preventive side, 80.5% of adults reported an annual checkup (CDC PLACES, 2023), higher than 97% of U.S. counties. Cholesterol screening reached 86.5% (CDC PLACES, 2023), also above 93% of counties nationally. Residents are seeing their doctors.
The chronic disease numbers are less favorable. Obesity affects 39.6% of adults (CDC PLACES, 2023). High blood pressure runs at 41% (CDC PLACES, 2023), ranking above 93% of U.S. counties and 94% within Tennessee. Diabetes prevalence is 14.6% (CDC PLACES, 2023), also above 92% of U.S. counties. These three conditions cluster together and correlate with each other, and all three run well above national averages in Shelby County.
Depression affects 25.2% of adults (CDC PLACES, 2023), which ranks at the lower end within Tennessee (lower than 100% of the state's other counties) but above 62% of U.S. counties. Poor mental health days affect 19.7% of adults (CDC PLACES, 2023). Poor physical health days run at 13.8% (CDC PLACES, 2023).
About 12.4% of residents lack health insurance (CDC PLACES, 2023), higher than 68% of U.S. counties but lower than 75% of Tennessee counties. The county has better insurance coverage than most of the state, likely tied to employer-provided plans in the Memphis metro's healthcare and logistics sectors.
The pattern here is clear: residents access care at high rates, but chronic conditions remain widespread. Access alone isn't solving the underlying health burden.
Climate & Natural Disasters
Shelby County averages 63.6°F annually (NOAA Climate Data Online, 2025), warmer than 82% of U.S. counties. Highs average 73.6°F and lows 53.8°F, a range that keeps the county firmly in four-season territory without the harsh winters of the upper Midwest.
The rain is the story. At 60.3 inches per year (NOAA Climate Data Online, 2025), Shelby County gets more rain than 96% of U.S. counties. That's more than Seattle. Snow is modest by comparison, averaging 8.2 inches annually (NOAA Climate Data Online, 2025), but what arrives tends to cause disproportionate disruption in a region that doesn't always have the infrastructure to handle it.
The county has 28 federal disaster declarations on record (FEMA OpenFEMA, 2026), more than 82% of U.S. counties. Severe storms account for most of them. There have been 15 severe storm declarations since 1994, plus four winter storm events, two floods, and two severe ice storms. The most recent two declarations both came in early 2026, both winter storms, within two weeks of each other.
That pattern is worth noting for anyone planning around weather risk. The county isn't in a high-tornado corridor or on a flood plain by default, but it gets hit regularly. The 2011 cluster alone produced three major storm declarations in a single month, including a flood emergency in May.
Climate here is mild by national standards. The disaster history suggests the real exposure isn't temperature extremes but the frequency of severe weather events that, individually, might seem manageable.
Financial Profile
Total adjusted gross income reported from Shelby County was $34.1 billion across 435,870 tax returns (IRS Statistics of Income, 2021). Both figures rank in the top 2-3% nationally. Average AGI was $78,346, and average total income was $79,201 per return (IRS Statistics of Income, 2021), both above 81% of U.S. counties.
Banking access is strong. The county has 474 bank branches holding $71.5 billion in total deposits (FDIC Summary of Deposits, 2023). Both figures rank above 99% of U.S. counties. Memphis is a regional banking center, and the branch density reflects that.
Social Security beneficiaries totaled 169,065 (SSA OASDI, 2024), above 98% of U.S. counties. That's roughly 18% of the total population receiving OASDI benefits, a figure consistent with the county's younger-than-average median age. In older counties, this ratio can climb above 25%.
Key Comparisons
Shelby County sits at the intersection of scale and disparity. Here's how it stacks up.
Against national medians, the county runs above average on population, labor force, educational attainment, banking access, and preventive healthcare engagement. It runs below average on median household income, graduation rates, and per-pupil spending.
Against Tennessee, Shelby County leads on almost every scale metric (population, enrollment, deposits, tax returns) and on income measures like per capita income and average AGI. It falls behind on graduation rate (lowest in the state) and unemployment rate (higher than 84% of state counties).
The most striking contrasts are internal. A 34.2% bachelor's attainment rate paired with a 79.2% high school graduation rate. Average AGI of $78,346 alongside a 17.2% poverty rate. High preventive care engagement (80.5% annual checkups) next to high chronic disease rates (41% high blood pressure, 39.6% obesity).
Shelby County generates more aggregate wealth, files more tax returns, and holds more bank deposits than nearly every county in the country. But the median household earns less than half of U.S. counties. The gap between aggregate and individual measures defines much of what the data shows.
Mean commute time is 20.4 minutes (Census ACS 5-Year, 2023), shorter than 65% of U.S. counties, which is typical of cities with broad, car-oriented road networks rather than long suburban rail commutes.
