Birth year · Baby Boomers · 1946–1964
Born into a world of 2.40 billion people, in a year when about 3.4 million babies were born in the United States.
Someone born in 1946 is a Baby Boomer, the generation born 1946–1964. Pew Research Center draws the same boundary. Someone born in 1946 turns 80 in 2026. About 3.4 million babies were born in the United States that year (National Center for Health Statistics, adjusted for under-registration). There is no UN estimate of worldwide births before 1950.
| World population | 2.40 billion |
| Babies born worldwide | n/a |
| Babies born in the United States | 3.4 million |
| Children per woman, worldwide | n/a |
| Life expectancy at birth, worldwide | n/a |
The UN's World Population Prospects, the source of the worldwide births, fertility and life-expectancy figures on the pages from 1950, starts in 1950, so those rows read n/a here rather than carry an estimate of ours. World population is Our World in Data's long-run series, which uses Gapminder's estimates for the years before 1950. US births are the National Center for Health Statistics series, which starts in 1909 and is adjusted for under-registration until 1958. Pages before 1950 list no events: we add history only where each item has been checked.

The cohort this year belongs to
Born between 1946 and 1964 during the post-war birth spike. Boomers hold roughly half of global wealth while making up about 14% of the population.
Cohort boundaries are hard lines drawn through a continuous thing. A child born a day before or after one of them lands in a different generation with an identical childhood.

About 3.4 million in the United States, the National Center for Health Statistics figure adjusted for under-registration. There is no comparable worldwide figure: UN World Population Prospects, the source of the worldwide count on later years, starts in 1950, and we do not estimate one.

Baby Boomers. 1946 is the first year of Baby Boomers and Silent Generation ends in 1945. People born near a boundary often identify with both, and the line is a convention rather than a measured break.
