About this Dataset

The population levels in the chart and table are the BEA's total US population series, published on FRED as POPTHM, taken at July of each year. That series counts the resident population plus US armed forces stationed overseas, so it runs slightly above the Census Bureau's resident estimate: Census Vintage 2025 puts the July 2025 resident population at 341.78 million, against 342.08 million in the BEA series.

The components of change come from the Census Bureau's Population Estimates Program (PEP), which extends the most recent decennial census with records of births, deaths and migration.

  • Population level: BEA total population incl. armed forces overseas, July of each year, 1966–2025
  • Natural increase and net international migration: Census PEP, national totals, July-to-July years
  • Median age: Census Vintage 2024 national estimates by single year of age
  • Components of change: Births, deaths, domestic migration, international migration — separately tracked by Census

Net international migration fell from 2.73 million in 2024 to 1.26 million in 2025, according to Census Vintage 2025, while natural increase held near 0.5 million a year in both years. The net international migration column uses Vintage 2025 for 2021–2025 and Vintage 2020 for 2011–2020; each vintage is benchmarked to a different decennial census base, so the two stretches are not fully comparable. Census revises each year's estimates with every new vintage.

Frequently Asked Questions

The Census Bureau's Population Estimates Program (PEP) produces annual estimates of resident population at the national, state, and county levels, broken down by age, sex, race, and Hispanic origin. Estimates combine the most recent decennial census count with records of births, deaths, and migration (domestic and international) over the subsequent years. They are used to allocate federal funding and as the official benchmark for planning and research.

Demographics are a core driver of long-term structural trends across asset classes. Ageing populations imply rising healthcare spending, increasing pension liabilities, and lower potential GDP growth. Younger, growing populations support consumer demand and labour supply. Real estate valuations are driven partly by household formation rates (a function of demographics). Pension funds model contribution and liability assumptions directly from population projections. Private equity's healthcare and senior living sectors are sized against demographic forecasts.

Estimates are backward-looking — they extend the decennial census forward using recorded births, deaths, and migration data. Projections are forward-looking model outputs using assumed fertility rates, mortality rates, and net migration scenarios. The Census Bureau's most recent national projections run through 2100 and include alternative immigration scenarios. Projections are inherently uncertain over longer horizons; estimates are considered authoritative for the periods they cover.
