United States: birth background and country comparison
- Population
- 343,477,000 people
- Annual births
- 3,657,476 births per year
- Life expectancy at birth
- 79.3 years
United States: the share of annual births across the 172 places in this game dataset is 2.7722%. The population baseline is 343,477,000, and annual births total 3,657,476. These figures describe a shared starting context, not an individual's future.
A mixed-year snapshot covering 172 countries, not live statistics. Sources, missing values and limitations
Put the numbers in context. Current selection: United States. Compare the data with a place you choose, then see why a country’s birth share and population share can differ.

How should I read these numbers?
Life expectancy and expected years of schooling describe populations, not an individual's lifespan or graduation date. Under-five mortality is per 1,000 live births, not a percentage. GDP per person at purchasing power parity is not salary. Reference years differ, so these rows do not establish causes or time trends.
More births does not mean the same population share
The two homepage sampling modes use different denominators. For the selected place (United States), this table explains its weight in the dataset; it does not change your game settings.
| Sampling basis | Country baseline | Share of dataset |
|---|---|---|
| Annual births | 3,657,476 births per year | 2.7722% |
| Total population | 343,477,000 people | 4.2517% |
Denominators: 131,932,758 births per year or 8,078,638,000 people across the 172 countries in this dataset. Both modes start at age zero. You cannot choose your birth country. These model weights are not live global statistics or your personal birth odds.

From the data to a life
Random sampling provides a starting background. Later events combine the character's circumstances, choices and randomness.

tsunamis; volcanoes; earthquake activity around Pacific Basin; hurricanes along the Atlantic and Gulf of America coasts; tornadoes in the Midwest and Southeast; mud slides in California; forest fires in the west; flooding; permafrost in northern Alaska is a major impediment to development volcanism: volcanic activity in the Hawaiian Islands, Western Alaska, the Pacific Northwest, and in the Northern Mariana Islands; Mauna Loa (4,170 m) in Hawaii and Mount Rainier (4,392 m) in Washington have been deemed Decade Volcanoes by the International Association of Volcanology and Chemistry of the Earth's Interior, worthy of study due to their explosive history and close proximity to human populations; Pavlof (2,519 m) is the most active volcano in Alaska's Aleutian Arc and poses a significant threat to intercontinental air travel; St. Helens (2,549 m), famous for the devastating 1980 eruption, remains active today; other historically active volcanoes are mostly concentrated in the Aleutian arc and Hawaii, including (in Alaska) Aniakchak, Augustine, Chiginagak, Fourpeaked, Iliamna, Katmai, Kupreanof, Martin, Novarupta, Redoubt, Spurr, Wrangell, Trident, Ugashik-Peulik, Ukinrek Maars, Veniaminof, (in Hawaii) Haleakala, Kilauea, Loihi, (in the Northern Mariana Islands) Anatahan, (in the Pacific Northwest) Mount Baker, and Mount Hood; see note 2 under "Geography - note"
Organized violence within country borders, 2023–24
No qualifying organized-violence event is recorded in these two country-year rows.
These are historical event records, not a current safety assessment. A recorded event is not itself an active-war classification; no recorded event does not establish peace.

Sources and interpretation
The existing baseline draws on UN World Population Prospects 2024 and World Bank development indicators, among other public statistics. It combines different reference years; individual observation years and estimation flags were not retained. Consult the original series before using these figures for research or current decisions.
The supplementary indicators retain values from a reference model. Some missing observations in the original model may have been replaced with regional averages; affected values are not individually flagged. Individual values have not all been checked against the original statistical agencies. These are not current live measurements.
For definitions and source context, consult UN Inter-agency Group for Child Mortality Estimation, UNAIDS HIV data, WHO road safety and health expenditure data, and World Happiness Report. These are source-lineage references, not a claim that every value matches the current series.
The dataset covers 172 places. Birth shares are calculated within this covered set, not from a complete live global census. Missing values remain missing. Gross tertiary enrollment can exceed 100%; GDP at PPP is not a salary, and the Gini index here uses a 0–1 scale. Game estimates are not official forecasts.
