Birth year · Greatest Generation · 1901–1927
Born into a world of 2.01 billion people, in a year when about 2.8 million babies were born in the United States.
Someone born in 1927 is the Greatest Generation, the generation born 1901–1927. Pew Research Center counts everyone born before 1928 as the Greatest Generation. Someone born in 1927 turns 99 in 2026. About 2.8 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 | 2.01 billion |
| Babies born worldwide | n/a |
| Babies born in the United States | 2.8 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 1901 and 1927 and named by Tom Brokaw. Fewer than five million are still alive, all of them aged 99 or over.
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.

They are the Greatest Generation, the cohort born from 1901 to 1927. Pew Research Center counts everyone born before 1928 as the Greatest Generation.
They turn 99 during 2026, or are already 99 if their birthday has passed.
About 2.8 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.
About 2.01 billion, from Our World in Data's long-run population series, which uses Gapminder's estimates for the years before 1950.
Greatest Generation. 1927 is the last year of Greatest Generation and Silent Generation starts in 1928. People born near a boundary often identify with both, and the line is a convention rather than a measured break.
