Interactive: How Do Americans Differ by Age?

The human experience changes dramatically over the course of a lifetime.

While we each intrinsically know that our days as teenagers will be vastly different from those as senior citizens, it is interesting to see how this looks from a 10,000-foot perspective.

Using demographic data on the American populace, we can spot key differences between age groups, including some aspects that make each generation of Americans unique.

The U.S. Population, by Age

Today’s interactive data visualization comes to us from Overflow Data, and it charts out the entire U.S. population by age group.

The graphic allows you to sort demographics based on data pertaining to specific topics—such as whether people own or rent their house—to see how age affects answers to these different questions. The interactive visualization also allows you to filter results by geographic region, sex, marital status, or employment status.

Data here comes from the 2017 Public Use Microdata Sample (PUMS) via the American Community Survey, which is published by the U.S. Census Bureau.

Gauging Differences

Let’s dive into how American differ by age, by looking at some specific charts:

Employment Status, by Age

This is a simple one to start with, but it makes it easy to see how the data works. In the below chart, it’s evident that most younger and older Americans are not in the labor force, while the majority of working age Americans are employed or seeking work (unemployed).

Employment Status of Americans, by Age

Own or Rent, by Age

How about looking at whether Americans own or rent, or even if they live in a group quarters?

Own or Rent, by Age

Race, by Age

The below chart is sorted by percentile, and it shows the percentage of individuals by race according to their age group. As the population skews younger, so does its racial diversity.

Marital Status, by Age

The below chart is sorted by percentile, and it shows the marital status (married, divorced, etc.) of different age groups.

Ranked: The Most Populous Cities in the World

More than half of the world’s population currently lives in cities—and as time goes on, it’s clear that more urban dwellers will find themselves living in megacities.

Megacities are defined as urban areas with a population of more than 10 million people. This means that the world’s top 20 most populous cities are all megacities.

This visualization, using data from Macrotrends, shows the 20 most populous cities in the world.

Rapid Urbanization

Today, more than 80% of people in higher income countries find themselves living in urban areas, and in upper-middle income countries the number lies between 50-80%.

Rural-to-urban migration is an increasingly relevant trend in the 21st century. Prospects of better job opportunities and higher wages, along with shifts from agrarian to industrial and service-based economies, are causing mass movement to cities.

How much have the world’s five most populous cities grown in just the last decade?

RankCity 2010 Population 2020 Population Percentage Change
#1🇯🇵 Tokyo36,834,00037,393,000+1.5%
#2🇮🇳 Delhi21,935,00030,291,000+38.1%
#3🇨🇳 Shanghai19,980,00027,058,000+35.4%
#4🇧🇷 São Paulo19,660,00022,043,000+12.1%
#5🇲🇽 Mexico City 20,132,00021,782,000+8.2%

While Tokyo only gained 559,000 people between 2010 and 2020, Delhi gained over 8 million people in the same time frame.

Shanghai grew by over 7 million people. Meanwhile, São Paulo grew by more than 2 million, and Mexico City gained just over 1.6 million people.

Interestingly, Mexico City placed third on the top largest cities list in 2010, but has since experienced slower growth compared to its competitors, Shanghai and São Paulo.

The Most Populous Cities Today

While Tokyo is the world’s most populous city with 37,393,000 people, this number is leveling out due to declining birth rates and an aging population.

Indian and Chinese cities, on the other hand, will continue to grow rapidly in the coming years. In fact, it’s expected that Delhi’s population could surpass Tokyo’s by 2028.

Here’s a closer look at the top 20 most populous cities.

18🇨🇩 Kinshasa14,342,000
19🇵🇭 Manila13,923,000
20🇨🇳 Tianjin13,580,000

By 2035, two new cities are expected to crack the top 20 list. Specifically, it’s projected that Bangalore (India) and Lahore (Pakistan) will boot out Tianjin and Buenos Aires. In addition, Guangzhou, Shenzhen, and Chennai are all expected to meet the megacity definition by 2035.

Urban growth will continue mainly in Asia and Africa, as some cities in regions such as Europe actually begin to shrink in population due to aging citizens and declining birth rates. Since 2012, deaths in the EU have actually been outpacing births—and in 2019, there were 4.7 million deaths compared to 4.2 million births, though net migration kept population numbers from falling.

Life in the City

While there are certainly downsides to mass urbanization, like pollution and overcrowding, the upsides clearly outweigh the negatives for most people. Convenience, better jobs, easier access to social services, and higher wages are among the many reasons people are likely to continue to move to cities, even in the post-COVID era.

With the emergence of smart and green cities, the quality of life for many urban dwellers will likely continue to improve, and more large urban areas will morph into megacities.

Visualizing the U.S. Population by Race

America is a cultural mosaic—nearly 40% identify as a visible minority today. Here we break down the U.S. population by race by state.

Visualizing the U.S. Population by Race

The American population is a unique mosaic of cultures—and almost 40% of people identify as racial or ethnic minorities today.

In this treemap, we use data for 2019 from the Kaiser Family Foundation, which bases its analysis on the latest American Community Survey (ACS) data from the U.S. Census Bureau. Then we break down the same data on a state-by-state basis.

Growing Diversity in America

As of 2019, here is the current distribution of the U.S. population by race and ethnicity:

  • White: 60.1% (Non-Hispanic)
  • Hispanic: 18.5%
  • Black: 12.2%
  • Asian: 5.6%
  • Multiple Races: 2.8%
  • American Indian/Alaska Native: 0.7%
  • Native Hawaiian/Other Pacific Islander: 0.2%

Note that the U.S. totals do not include Puerto Rico.

However, these race and ethnicity projections are expected to change over the coming years. By the year 2060, it’s expected that the distribution of Non-Hispanic Whites as a percentage of total population will fall from 60.1% to 44.3% of Americans.

YearWhite*BlackHispanicAsianMultiple RacesOther**
202059.7%12.5%18.7%5.8%2.3%0.9%

206044.3%13.6%27.5%8.9%4.9%0.9%

Source: U.S. Census Bureau. *Excludes Hispanics **Other includes American Indian/Alaska Native (0.7%) and Native Hawaiian/Pacific Islander (0.2%). Both proportions remain unchanged in these projections.

Interestingly, the proportion of those from multiple racial and ethnic backgrounds will more than double, from 2.3% to 4.9% alongside rising patterns of interracial marriage.

Over time, the U.S. Census has been vastly expanded to reflect the true diversity that the country holds. In fact, it was only from 1960 onwards that people could select their own race—and only from 2020 can those who chose White or Black provide further information on their roots.

A State-by-State Breakdown

Of course, racial diversity in the United States differs widely from region to region.

In the Northeast—particularly the states Maine, Vermont, and New Hampshire—the Non-Hispanic White population accounts for 90% or more of the total. In contrast, Black populations are highest in the District of Columbia (45%) and several Southern states.

Of all the 50 states, Hawaii is home to the largest share of Asian populations at 39%. It also has one of the most diverse racial breakdowns in the nation overall, including the highest proportion of mixed race individuals.

Looking to another island, an overwhelming majority (98%) of Puerto Ricans are of Hispanic origins. While it’s not a state, its inhabitants are all considered U.S. citizens.

Charting the U.S. population by race is crucial for a number of reasons. This information can be used to better understand existing income and wealth gaps, track public health outcomes, and to aid in policy decision-making at higher levels.

We become not a melting pot but a beautiful mosaic. Different people, different beliefs, different yearnings, different hopes, different dreams.

—Jimmy Carter, 39th President of the U.S.
