Population Distribution By Age Through The Years

Here’s an animation of the U.S population distribution, by age, from 1900 through 2060, demonstrating the gradual aging of the US population.


“In 1900, the graph was fairly steep, but with improving health care, the graph has flattened out over the last 100 years… Watch for: 1) the original baby bust preceding the baby boom (the decline in births prior to and during the Depression). Those are the people currently in retirement. 2) the Baby Boom is obvious. 3) By 2020 or 2025, the largest cohorts will all be under 40.”
