Population Demographics

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

Published since 1962, PRB’s annual World Population Data Sheet tracks global population data. This year’s edition provides 24 population indicators for more than 200 countries and territories. Users can also explore key trends through an interactive map.

“As the experience with the COVID-19 pandemic has shown us, population changes such as aging and rapid urbanization are important factors for countries to consider as they plan for future disease outbreaks, long-term health care needs and other developments,” said Jeff Jordan, PRB president and CEO. “PRB’s World Population Data Sheet provides objective data and analysis policymakers need to make these decisions.”

Among the key findings for 2020:

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.

This entry gives an estimate from the US Bureau of the Census based on statistics from population censuses, vital statistics registration systems, or sample surveys pertaining to the recent past and on assumptions about future trends. The total population presents one overall measure of the potential impact of the country on the world and within its region. Note: Starting with the 1993 Factbook, demographic estimates for some countries (mostly African) have explicitly taken into account the effects of the growing impact of the HIV/AIDS epidemic.

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.

Today the U.S. Census Bureau is releasing results from the 2020 Census, marking the 24th time the nation’s population has been counted since the first census in 1790, when there were just 3.9 million people living in the United States.

The first census helped build the foundation of our democracy, and the census continues to be a cornerstone for our growing nation.

According to the 2020 Census, there were 331,449,281 people living in the United States as of April 1, 2020, which represents a growth of 7.4% since 2010. In the last 100 years, our nation has tripled in size.

Apportionment is the process of dividing the 435 memberships, or seats, in the U.S. House of Representatives among the 50 states. At the conclusion of each decennial census, the results are used to calculate the number of seats to which each state is entitled. Each of the 50 states is entitled to a minimum of one seat in the U.S. House of Representatives.

The 2020 Census apportionment population includes the resident population of the 50 states, plus a count of the U.S. military personnel and federal civilian employees living outside the United States (and their dependents living with them) who can be allocated to a home state. The population of the District of Columbia is not included in the apportionment population.

The U.S. population total and population change have been adjusted to be consistent with the results of the 2020 Census. The components of population change have not been adjusted and so inconsistencies will exist between population values derived directly from the components and the population displayed in the odometer and the Select a Date tool.

The U.S. population clock is based on a series of short-term projections for the resident population of the United States. This includes people whose usual residence is in the 50 states and the District of Columbia. These projections do not include members of the Armed Forces overseas, their dependents, or other U.S. citizens residing outside the United States.

Vera Institute of Justice researchers collected data on the number of people in local jails and state and federal prisons at both midyear and fall 2020 to provide timely information on how incarceration is changing in the United States during the COVID-19 pandemic. Researchers estimated the national jail population using a sample of 1,558 jail jurisdictions and the national prison population based on a sample of 49 states and the Federal Bureau of Prisons. Vera also collected data on people incarcerated and detained by the U.S. Marshals Service (USMS) and Immigration and Customs Enforcement (ICE).
