What the data says about United States

Every figure on this profile comes from a specific measurement methodology, and OECD member states like United States generally report the most complete and harmonized statistical series in this dataset: standardized definitions and cross-agency reconciliation between the World Bank, OECD, and WHO reduce, though never eliminate, the gaps that show up elsewhere. As one of the more populous OECD members, United States's national averages sit on top of a very large, often regionally diverse population, so a single headline figure can obscure sizeable internal variation between states, provinces, or metro areas. Reading several indicators side by side, rather than anchoring on one number, is the more reliable way to build a grounded picture of how people in United States actually live, work, and age.

United States sits in North America with a population of 340.1 million, placing it 3rd out of 217 countries by headcount. Its capital, Washington D.C., anchors a High income economy with total GDP of $28.8 trillion - ranked 1st globally, and GDP per capita of $84,534. This combination of demographic scale and economic output shapes everything from household purchasing power and domestic market depth to the country's weight in regional trade flows and international development programmes.

Life expectancy at birth in United States is 78.9 years, ranking 61st worldwide and offering a summary read on healthcare access, nutrition, sanitation, and long-run living standards. The World Bank's World Development Indicators, combined with the WHO Global Health Observatory and ILO ILOSTAT wage statistics plus OECD Health Statistics 2025, expose 46 data points across 8 thematic areas, from fertility and urbanisation to CO₂ emissions, school enrolment, and labour-force participation. Reading these indicators together, rather than in isolation, is what turns headline numbers into a grounded portrait of how people actually live.

Use the indicator tables below to track trajectories over time, jump to United States's placement on specific rankings such as GDP, population density, or life expectancy, and open the side-by-side Compare view to benchmark against peers inside North America or across income groups. Because all figures come from official, CC BY 4.0-licensed datasets with clear vintages, you can cite them directly in research or journalism. Where a field reads "N/A", the upstream agency has not yet released that value for United States - we never fabricate estimates or carry forward stale values, so missing points stay visible rather than quietly filled in.
