Beginning over 100 years ago, this video from Kaj Tallungs assesses how America's demographics have changed from 1901 to 2020. It uses data from multiple sources including the U.S. Census Bureau, the National Center for Health Statistics, and the Human Mortality Database.

A Look at the Total Population

As Visual Capitalist's Avery Koop notes, the most obvious takeaway from this animation is that America's population has soared over the last century. America's population grew from 77 million in 1901 to over 330 million in 2020—or total growth of 330% over the 119 years.

Demographic Breakdowns

Diving a little deeper, the country's demographic breakdowns have also changed significantly over the last 100+ years. While the share of men and women is an obvious near-even split, age and race distributions have changed drastically.

For starters, though birth rates have remained fairly strong in the U.S., they have been slowing over time. This is similar to many other Western countries, and can eventually result in a larger share of elderly people as well as an increased financial cost of subsidizing their care. Additionally, fewer births results in a depleting workforce as the young population shrinks.

The shares of Black, Asian, Hispanic, and people of two or more races have also been growing. In fact, between 2010–2020 the population of people identifying as two races or more increased by a whopping 276%.
