U.S. Population Estimated at 332,403,650 on Jan. 1, 2022

"As our nation prepares to ring in the new year, the U.S. Census Bureau projects the United States population will be 332,403,650 on Jan. 1, 2022.

This represents a 0.21% increase in population or an additional 706,899 people since New Year’s Day 2021.
Population increased 0.29% since Census Day, April 1, 2020, adding 954,369 people during that period.

In January 2022, the United States is expected to experience a birth every nine seconds and one death every 11 seconds. Meanwhile, net international migration is expected to add one person to the U.S. population every 130 seconds.

The combination of births, deaths and net international migration increases the U.S. population by one person every 40 seconds.

The projected world population on Jan. 1, 2022 is 7,868,872,451, an increase of 74,235,487, or 0.95%, from New Year’s Day 2021

During January 2022, 4.3 births and 2.0 deaths are expected worldwide every second..."

U.S. Census Bureau Estimates 7.58 Billion People on Earth on World Population Day

"

World population is estimated to reach 7.58 billion this month as World Population Day is celebrated on July 11 but the U.S. Census Bureau is projecting another milestone: Annual population growth will slip under 1.0% in 2020-2021 for the first time since 1950.

The United Nations declared July 11 as World Population Day in 1989, two years after world population crossed the 5 billion mark.

The U.S. Census Bureau’s International Data Base, which estimates that 7.58 billion people will be on the planet on that day, shows that world population increased by more than 50% in the 32 years since the Day of Five Billion in 1987..."

Population Estimates Show Aging Across Race Groups Differs

"The nation as a whole continues to grow older with the median age increasing to 38.2 years in 2018, up from 37.2 years in 2010. The pace of this aging is different across race and ethnicity groups, according to new 2018 Population Estimates by demographic characteristics for the nation, states and counties, released today by the U.S. Census Bureau.

From 2010 to 2018, the U.S. population’s median age increased by 1.0 years. Amongst the different race groups:

• The white alone-or-in-combination population increased by 1.0 years.
• The black or African American alone-or-in-combination population grew by 1.4 years.
• The American Indian and Alaska Native alone-or-in-combination population increased by 2.2 years.
• The Asian alone-or-in-combination population increased by 1.7 years.
• The Native Hawaiian and Other Pacific Islander alone-or-in-combination population increased by 2.6 years.
• The Hispanic (any race) population experienced an increase in median age of 2.2 years..."

The Nation’s Older Population Is Still Growing,

"The nation’s population has a distinctly older age profile than it did 16 years ago, according to new U.S. Census Bureau population estimates released today.

New detailed estimates show the nation’s median age — the age where half of the population is younger and the other half older — rose from 35.3 years on April 1, 2000, to 37.9 years on July 1, 2016.

“The baby-boom generation is largely responsible for this trend,” said Peter Borsella, a demographer in the Population Division. “Baby boomers began turning 65 in 2011 and will continue to do so for many years to come.”

Residents age 65 and over grew from 35.0 million in 2000, to 49.2 million in 2016, accounting for 12.4 percent and 15.2 percent of the total population, respectively.

These latest estimates present changes among groups by age, sex, race and Hispanic origin at the national, state and county levels between April 1, 2010, and July 1, 2016. The estimates also present changes over the same period among groups by age and sex for Puerto Rico and its municipios..."

After Hurricane Katrina: Where Are They Now?

"As you might know, we released the population estimates for cities and towns last week. However, following Hurricane Katrina in August 2005, the U.S. Census Bureau did not release these estimates for four Mississippi Gulf Coast communities— Bay St. Louis, Long Beach, Pass Christian and Waveland in 2006. The cities sustained severe damage from Katrina, and the impact to their populations and housing stock could not be reliably measured.
In the aftermath of the storm, the Gulf Coast would face many years of rebuilding, and learning how populations were rebounding would be critical for community leaders. For the Census Bureau, producing population estimates for places where many homes had been destroyed and people displaced presented a unique but vital challenge..."

How the U.S. Census Defines Race

"What does America look like? To find out, historians often turn to data from the U.S. Census, which has collected information on population and race since 1790. But the census doesn't just study race in America—the terminology used in census forms can also define it. A new interactive graphic released by the Census Bureau shows how racial categorizations have changed over time.

There's not much continuity to the labels for people of color, write Laris Karklis and Emily Badger forThe Washington Post. Their piece, which offers a few alternative graphics using census race categories, shows just how often the government defines and redefines racial identities. As the Census Bureau prepares for the 2020 count, here are a few key details from the past 225 years:

Freedom and Slavery 

From the beginning, the census reflected early American realities of slavery. The very first census, which was conducted in 1790, was ordered to distinguish "free persons, including those bound to service for a term of years, from all others; distinguishing also the sexes and colours of free persons, and the free males of sixteen years and upwards from those under that age." As a result, census takers counted free whites, "all other free persons," and slaves. No distinction was made between differing ethnicities, but "slave" almost always meant enslaved Africans..."

An Overview of the Employment-Population Ratio

"The Bureau of Labor Statistics (BLS) defines the employment-population ratio as the ratio of total civilian employment to the civilian noninstitutional population. Simply put, it is the portion of the population that is employed. The ratio is used primarily as a measure of job holders and to track the pace of job creation, relative to the adult population, over time.
The employment-population ratio has several properties that make it an attractive indicator for labor market analysis. It is easy to interpret and can be used to make meaningful comparisons across time and groups with dissimilar population size. Because it takes into account both the impacts of labor force participation and unemployment, it is a useful summary measure when those forces place countervailing pressures on employment. Like all labor market indicators, it has limits. For example, it does not distinguish between part-time and full-time employment, and it is silent on wages, benefits, and job conditions. Trends in the employment-population ratio also do not provide information about job flows (i.e., whether a drop in employment represents more people exiting employment or fewer new entrants).."

Projections of the Size and Composition of the U.S. Population: 2014 to 2060

"Between 2014 and 2060, the U.S. population is projected to increase from 319 million to 417 million, reaching 400 million in 2051. The U.S. population is projected to grow more slowly in future decades than in the recent past, as these projections assume that fertility rates will continue to decline and that there willbe a modest decline in the overall rate of net international migration. By 2030, one in five Americans is projected to be 65 and over; by 2044, more than half of all Americans are projected to belong to a minority group (any group other than non-Hispanic White alone); and by 2060, nearly one in five of the nation’s total
population is projected to be foreign born.."

Nation to Become a Plurality, but Some Areas Already Are

"While the nation is projected to become both a “majority-minority” and a “plurality” nation by 2043, some states and many counties have already crossed these thresholds. California, Hawaii, New Mexico, Texas, and the District of Columbia have populations that are already “majority-minority.” Nearly one-third of Americans already live in a “majority-minority” county. According to new Census Bureau estimates released today, this was the case in 355 (11 percent) of the nation’s 3,143 counties in 2013..."
