Birth year · Millennials · 1981–1996
Born into a world of 5.05 billion people, where women had 3.5 children on average and a newborn could expect to live to 63.
Someone born in 1987 is a Millennial — the generation born 1981–1996, a boundary Pew Research Center uses too. They turn 39 in 2026. About 141.3 million babies were born worldwide in 1987, about 3.9 million of them in the United States (UN estimates).
| World population | 5.05 billion |
| Babies born worldwide | 141.3 million |
| Babies born in the United States | 3.9 million |
| Children per woman, worldwide | 3.48 |
| Life expectancy at birth, worldwide | 63.2 years |
Every figure is a UN World Population Prospects 2024 estimate, republished by Our World in Data. Life expectancy is a period figure for the conditions of 1987, not a forecast for anyone born that year. Pages for years before 2010 list no events: we add history only where each item has been checked, and would rather show nothing than something half-remembered.

The cohort this year belongs to
Born between 1981 and 1996, Millennials are the generation that came of age with the commercial internet, and are now the parents of most of Generation Alpha.
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 Millennials, the cohort born from 1981 to 1996. Pew Research Center draws the same boundary. Some other sources put the lines a year or two away, so a year near a boundary can be labelled differently elsewhere.
They turn 39 during 2026, or are already 39 if their birthday has passed.
About 141.3 million worldwide and about 3.9 million in the United States, according to UN World Population Prospects 2024 estimates.
About 5.05 billion, according to UN World Population Prospects 2024.
About 63 years worldwide at birth, as a period estimate. That is the average for the conditions of 1987, not a prediction for any one person, and it is pulled down heavily by deaths in infancy.
