The year 2030 marks a demographic turning point for the United States. Beginning that year, all baby boomers will be older than 65 years of age. This will expand the size of the older population so that one in every five Americans is projected to be of retirement age. Later that decade, by 2034, we project that older adults will outnumber children for the first time in U.S. history. The year 2030 marks another demographic first for the United States. That year, because of population aging, immigration is projected to overtake natural increase (the excess of births over deaths) as the primary driver of population growth for the country.
 

Population in the world is currently (2020) growing at a rate of around 1.05% per year (down from 1.08% in 2019, 1.10% in 2018, and 1.12% in 2017). The current average population increase is estimated at 81 million people per year.

Annual growth rate reached its peak in the late 1960s, when it was at around 2%. The rate of increase has nearly halved since then, and will continue to decline in the coming years.

World population will therefore continue to grow in the 21st century, but at a much slower rate compared to the recent past. World population has doubled (100% increase) in 40 years from 1959 (3 billion) to 1999 (6 billion). It is now estimated that it will take another nearly 40 years to increase by another 50% to become 9 billion by 2037.

The federal prison population, which declined for the first time in decades under President Barack Obama, fell further during the administration of President Donald Trump.

The nation’s imprisonment rate is at its lowest level in more than two decades. The greatest decline has come among black Americans, whose imprisonment rate has decreased 34% since 2006.

There were 1,501 black prisoners for every 100,000 black adults at the end of 2018, according to a new report from the Bureau of Justice Statistics (BJS), the statistical agency of the U.S. Justice Department. That was down sharply from 2,261 black inmates per 100,000 black adults at the end of 2006, according to an earlier BJS study. These statistics only count inmates sentenced to more than a year in state or federal prison. They exclude inmates held in local jails and those sentenced to shorter periods of imprisonment.

The United States has more immigrants than any other country in the world. Today, more than 40 million people living in the U.S. were born in another country, accounting for about one-fifth of the world’s migrants. The population of immigrants is also very diverse, with just about every country in the world represented among U.S. immigrants.

Pew Research Center regularly publishes statistical portraits of the nation’s foreign-born population, which include historical trends since 1960. Based on these portraits, here are answers to some key questions about the U.S. immigrant population.

How many people in the U.S. are immigrants?

The coronavirus outbreak has pushed millions of Americans, especially young adults, to move in with family members. The share of 18- to 29-year-olds living with their parents has become a majority since U.S. coronavirus cases began spreading early this year, surpassing the previous peak during the Great Depression era.

The statistic shows the global population as of mid-2020, sorted by age. In mid-2020, approximately 23.7 percent of the global population were aged between 10 and 24 years.

In 2020, the COVID-19 pandemic affected drastically all forms of human mobility, including international migration. Around the globe, the closing of national borders and severe disruptions to international travel obliged hundreds of thousands of people to cancel or delay plans of moving abroad. Hundreds of thousands of migrants were stranded, unable to return to their countries, while others were forced to return to their home countries earlier than planned, when job opportunities dried up and schools closed.

Value Notes

Over the course of the nation’s history, there has been a slow but steady decrease in the size of the average U.S. household—from 5.79 people per household in 1790 to 2.58 in 2010. But this decade will likely be the first since the one that began in 1850 to break this long-running trend, according to newly released Census Bureau data. In 2018 there were 2.63 people per household.

Cities with fewer than 200,000 residents grew faster than larger metropolises between 2017 and 2018 as high housing prices chased many people away from big cities and their closest suburbs.

The biggest cities grew by a collective 326,000 people, less than half the number earlier in the decade, and less than the number for smaller cities — 421,000 for cities with populations between 10,000 and 50,000.
