According to the Bureau's U.S. Population Clock, on January 28, 2021, the U.S. population had a net gain of one person every 100 seconds, or about 864 people per day. In 2018, 52% of Americans age 15 and over were married, 6% were widowed, 10% were divorced, and 32% had never been married. In 2020, the U.S. had a total fertility rate stood at 1.64 children per woman and the world's highest rate (23%) of children living in single-parent households.

The United States of America has a diverse population; 37 ancestry groups have more than one million members. White Americans with ancestry from Europe, the Middle East or North Africa, form the largest racial and ethnic group at 57.8% of the United States population. Hispanic and Latino Americans form the second-largest group and are 18.7% of the United States population. African Americans constitute the nation's third-largest ancestry group and are 12.1% of the total United States population. Asian Americans are the country's fourth-largest group, composing 5.9% of the United States population, while the country's 3.7 million Native Americans account for about 1%. In 2020, the median age of the United States population was 38.5 years.

In 2018, there were almost 90 million immigrants and U.S.-born children of immigrants in the United States, accounting for 28% of the overall U.S. population. In 2017, out of the U.S. foreign-born population, some 45% (20.7 million) were naturalized citizens, 27% (12.3 million) were lawful permanent residents, 6% (2.2 million) were temporary lawful residents, and 23% (10.5 million) were unauthorized immigrants. The United States led the world in refugee resettlement for decades, admitting more refugees than the rest of the world combined.

### Language

Main article: Languages of the United States

English (specifically, American English) is the de facto national language of the United States. Although there is no official language at the federal level, some laws—such as U.S. naturalization requirements—standardize English, and most states have declared English as the official language. Three states and four U.S. territories have recognized local or indigenous languages in addition to English, including Hawaii (Hawaiian), Alaska (twenty Native languages), South Dakota (Sioux), American Samoa (Samoan), Puerto Rico (Spanish), Guam (Chamorro), and the Northern Mariana Islands (Carolinian and Chamorro). In Puerto Rico, Spanish is more widely spoken than English.

According to the American Community Survey, in 2010 some 229 million people (out of the total U.S. population of 308 million) spoke only English at home. More than 37 million spoke Spanish at home, making it the second most commonly used language in the United States. Other languages spoken at home by one million people or more include Chinese (2.8 million), Tagalog (1.6 million), Vietnamese (1.4 million), French (1.3 million), Korean (1.1 million), and German (1 million).

The most widely taught foreign languages in the United States, in terms of enrollment numbers from kindergarten through university undergraduate education, are Spanish (around 7.2 million students), French (1.5 million), and German (500,000). Other commonly taught languages include Latin, Japanese, American Sign Language, Italian, and Chinese.

 Protestant (40%)

 Catholic (21%)

 Mormonism (2%)

 Orthodox (1%)

 Unaffiliated (29%)

A large variety of faiths have historically flourished within the country. According to the World Values Survey in 2017, the United States is more secular than the median country; they ranked the United States the 32nd least religious country in the world. Until the 1990s, the country was a substantial outlier among other highly developed countries: uniquely combining a high level of religiosity and wealth, although this has lessened significantly since then. Studies during the early 2020s found that about 81% of Americans believe in some conception of God, 45% report praying on a daily basis, 41% report that religion plays a very important role in their lives, and 31% report attending religious services weekly or near weekly. 58% of Americans report "seldom" or "never" attending religious services.

In a 2020 survey, about 64% of adults in the United States identified themselves as Christians making it the country with the largest Christian population. Protestantism is the largest Christian religious grouping in the United States, accounting for around a third of all Americans. In the so-called Bible Belt, located primarily within the Southern United States, socially conservative evangelical Protestantism plays a significant role culturally. By contrast, religion plays the least important role in New England and the Western United States.

Another 6% claimed a non-Christian faith; the largest of which are Judaism, Islam, Hinduism, and Buddhism.

Around 30% of Americans describe themselves as having no religion. Membership in a house of worship fell from 70% in 1999 to 47% in 2020, much of the decline related to the number of Americans expressing no religious preference. Membership also fell among those who identified with a specific religious group. According to *Gallup*, trust in "the church or organized religion" has declined significantly since the 1970s.

The First Amendment of the U.S. Constitution guarantees the free exercise of religion and forbids Congress from passing laws respecting its establishment.

### Urbanization

Main articles: Urbanization in the United States and List of United States cities by population

About 82% of Americans live in urban areas, including suburbs; about half of those reside in cities with populations over 50,000. In 2008, 273 incorporated municipalities had populations over 100,000, nine cities had more than one million residents, and four cities (New York City, Los Angeles, Chicago, and Houston) had populations exceeding two million. Many U.S. metropolitan populations are growing rapidly, particularly in the South and West.

### Education

The University of Virginia, founded by Thomas Jefferson, is one of the many public colleges and universities in the United States.
American public education is operated by state and local governments and regulated by the United States Department of Education through restrictions on federal grants. In most states, children are required to attend school from the age of five or six (beginning with kindergarten or first grade) until they turn 18 (generally bringing them through twelfth grade, the end of high school); some states allow students to leave school at 16 or 17. Of Americans 25 and older, 84.6% graduated from high school, 52.6% attended some college, 27.2% earned a bachelor's degree, and 9.6% earned graduate degrees. The basic literacy rate is approximately 99%.

The United States has many private and public institutions of higher education. The majority of the world's top public and private universities, as listed by various ranking organizations, are in the United States. There are also local community colleges with generally more open admission policies, shorter academic programs, and lower tuition. The U.S. spends more on education per student than any nation in the world, spending an average of $12,794 per year on public elementary and secondary school students in the 2016–2017 school year. As for public expenditures on higher education, the U.S. spends more per student than the OECD average, and more than all nations in combined public and private spending. Despite some student loan forgiveness programs in place, student loan debt has increased by 102% in the last decade, and exceeded 1.7 trillion dollars as of 2022.

### Health

The Texas Medical Center in downtown Houston is the largest medical complex in the world.
In a preliminary report, the Centers for Disease Control and Prevention (CDC) announced that U.S. life expectancy at birth had dropped to 76.4 years in 2021 (73.2 years for men and 79.1 years for women), down 0.9 years from 2020. This was the second year of overall decline, and the chief causes listed were the COVID-19 pandemic, accidents, drug overdoses, heart and liver disease, and suicides. Life expectancy was highest among Asians and Hispanics and lowest among Blacks and American Indian–Alaskan Native (AIAN) peoples. Starting in 1998, the average life expectancy in the U.S. fell behind that of other wealthy industrialized countries, and Americans' "health disadvantage" gap has been increasing ever since. The U.S. also has one of the highest suicide rates among high-income countries, and approximately one-third of the U.S. adult population is obese and another third is overweight.

In 2010, coronary artery disease, lung cancer, stroke, chronic obstructive pulmonary diseases, and traffic collisions caused the most years of life lost in the U.S. Low back pain, depression, musculoskeletal disorders, neck pain, and anxiety caused the most years lost to disability. The most harmful risk factors were poor diet, tobacco smoking, obesity, high blood pressure, high blood sugar, physical inactivity, and alcohol consumption. Alzheimer's disease, substance use disorders, kidney disease, cancer, and falls caused the most additional years of life lost over their age-adjusted 1990 per-capita rates. Teenage pregnancy and abortion rates in the U.S. are substantially higher than in other Western nations, especially among blacks and Hispanics.

The U.S. health care system far outspends that of any other nation, measured both in per capita spending and as a percentage of GDP but attains worse healthcare outcomes when compared to peer nations. The United States is the only developed nation without a system of universal health care, and a significant proportion of the population that does not carry health insurance. The U.S., however, is a global leader in medical innovation, measured either in terms of revenue or the number of new drugs and devices introduced.

Government-funded health care coverage for the poor (Medicaid, established in 1965) and for those age 65 and older (Medicare, begun in 1966) is available to Americans who meet the programs' income or age qualifications. In 2010, former President Obama passed the Patient Protection and Affordable Care Act or ACA, which the CDC said that the law roughly halved the uninsured share of the population and multiple studies have concluded that ACA had reduced the mortality of enrollees. However, its legacy remains controversial.
