Use the slider to change the years from 2010 to 2019. Note the “baby boomer” bulge at ages 44-64 in 2010 moves upward as that population cohort ages. Simultaneously, birth rates decline, as shown by narrowing of the base of the pyramid. Thus, the proportion elders in the total population will remain high and then grow.

The moving graph shows the age distribution of people making up the U.S. Population at different years from 1900 to 2060. There are relatively very few older people at first. Note the “baby boom” bump forming at the left as births increase dramatically at 1945. High birth rate continue until bump is complete by 1965 as birth rates decline. As the people making up the “baby boom” bump age with passing years, the bump moves to the right. Even as the bump fades at 2020, it has produced a dramatic increase in the proportion of elders in the population. That increase remains for years after 2025.
