Memphis Metro Population and Demographics

The Memphis metropolitan statistical area spans a multi-state footprint across Tennessee, Mississippi, and Arkansas, making its population and demographic profile more complex than that of the city of Memphis alone. This page covers the geographic scope of the metro area, how the U.S. Census Bureau defines and measures its population, the demographic composition of the region, and the analytical distinctions that matter when comparing metro-level data to municipal data. These distinctions carry direct implications for infrastructure planning, federal funding formulas, and economic analysis.

Definition and scope

The Memphis Metropolitan Statistical Area (MSA) is defined by the U.S. Office of Management and Budget (OMB) as a core-based statistical area anchored by Shelby County, Tennessee, where the city of Memphis is located (OMB Bulletin 23-01). The full MSA extends across 8 counties in 3 states: Shelby, Fayette, and Tipton counties in Tennessee; DeSoto, Marshall, Tate, and Tunica counties in Mississippi; and Crittenden County in Arkansas.

The 2020 U.S. Census placed the Memphis MSA population at approximately 1,336,000 residents (U.S. Census Bureau, 2020 Decennial Census). The city of Memphis itself accounted for roughly 633,000 of those residents — meaning approximately 53 percent of the metro population lives outside Memphis city limits. This gap between the city and the broader metro is a recurring source of analytical confusion when interpreting workforce, income, and poverty statistics. For a direct comparison of what "Memphis" means in different measurement contexts, see Memphis Metro vs City of Memphis.

The Memphis Metro Statistical Area page provides additional technical detail on OMB delineation criteria and how county-level commuting patterns determine MSA boundary changes between decennial census cycles.

How it works

The Census Bureau collects and publishes population and demographic data through two primary instruments: the decennial census (conducted every 10 years) and the American Community Survey (ACS), which produces rolling 1-year and 5-year estimates. The ACS 5-year estimates are generally preferred for sub-county and small-population analyses because they aggregate data across 60 months of surveys, reducing margin-of-error for smaller geographic units (U.S. Census Bureau, American Community Survey Information Guide).

Demographic composition of the Memphis MSA, as measured by the 2020 Census, breaks down across the following dimensions:

  1. Race and ethnicity: The Memphis metro is majority Black or African American by population share within Shelby County — approximately 54 percent of Shelby County residents identified as Black or African American in 2020 (U.S. Census Bureau, Explore Census Data). The broader 8-county MSA has a lower share due to the predominantly white populations of the suburban Tennessee and Mississippi counties.
  2. Age structure: The median age in the Memphis MSA is approximately 36 years, below the national median of 38.8 years (U.S. Census Bureau, 2020 Census Age and Sex data).
  3. Household composition: Average household size across the MSA tracks near 2.5 persons, consistent with broader mid-South regional patterns.
  4. Educational attainment: ACS 5-year estimates indicate that approximately 28 percent of Memphis MSA adults 25 and older hold a bachelor's degree or higher, compared to the national rate of approximately 33 percent (U.S. Census Bureau ACS).
  5. Foreign-born population: The foreign-born share of the Memphis MSA population is approximately 7 percent, well below the national average of about 13.6 percent (U.S. Census Bureau, 2020 Census).

Population growth across the MSA has been uneven. DeSoto County, Mississippi — the most populous Mississippi county in the metro — has been one of the fastest-growing counties in the mid-South, driven largely by suburban expansion from Memphis's Tennessee suburbs southward across the state line. The Memphis Metro Mississippi Border page addresses the cross-state dynamics that shape this growth pattern.

Common scenarios

Demographic data for the Memphis metro is applied in three distinct operational contexts:

Federal funding allocation: Population counts and poverty rates directly determine the Memphis metro's share of formula-based grants under programs administered by the U.S. Department of Housing and Urban Development (HUD) and the U.S. Department of Transportation. Community Development Block Grant (CDBG) allocations, for example, are calculated in part using low- and moderate-income population thresholds derived from Census and ACS data (HUD CDBG Program). The Memphis Metro Federal Funding and Memphis Metro Poverty Rate pages document how these thresholds apply locally.

Labor market analysis: Employers, site selectors, and workforce development agencies use MSA-level demographic data to assess available labor pools, skill gaps, and wage benchmarks. The Memphis Metro Job Market page draws on Bureau of Labor Statistics (BLS) data that uses MSA boundaries consistent with OMB definitions.

School district planning: Demographic projections at the county and sub-county level inform enrollment forecasts and capital planning for the 8-plus school districts operating across the MSA's 3-state footprint. The Memphis Metro School Districts page maps jurisdictional boundaries against population density data.

Decision boundaries

The most consequential analytical boundary in Memphis metro demographics is the distinction between city, county, and MSA geographies. Three comparisons illustrate where errors commonly occur:

City of Memphis vs. Shelby County: Memphis city limits contain approximately 633,000 residents; Shelby County as a whole contains approximately 929,000 — a difference of roughly 296,000 people who live in Shelby County but outside Memphis. Unincorporated Shelby County and municipalities such as Bartlett, Germantown, Collierville, and Millington account for this gap. Demographic profiles differ significantly: suburban Shelby County municipalities show higher median household incomes and lower poverty rates than the city core. See Memphis Metro Median Household Income for income distribution data across these geographies.

Shelby County vs. the full 8-county MSA: Adding the 7 counties outside Shelby expands the total population by roughly 400,000 and introduces predominantly rural, lower-density communities. DeSoto County, Mississippi is the dominant contributor, with a population exceeding 180,000 (U.S. Census Bureau). The Memphis Metro Counties page details individual county profiles.

MSA vs. Combined Statistical Area (CSA): The OMB also defines a Memphis–Forrest City Combined Statistical Area that adds Cross County and St. Francis County in Arkansas to the 8-county MSA. The CSA population exceeds 1.4 million. CSA boundaries are used less frequently in federal program administration but appear in some regional economic analyses. Readers researching the full scope of the metro should consult the Memphis Metro Area Overview page, which situates all these geographic layers in a single reference framework.

Population data for the Memphis metro is consistently updated through the Census Bureau's Population Estimates Program (PEP), which produces annual intercensal estimates at the county and MSA level. These estimates, not the decennial census, are used for most year-to-year program administration and are available through the U.S. Census Bureau main reference index.
