How Many People Are Married in the United States Today
In the United States, about 198 million adults aged 18 and older are married, based on the most recent available data. This represents roughly 60 percent of all U.S. adults in that age group. The exact number fluctuates with new marriages, divorces, deaths, and demographic shifts, but marriage remains a common household and social milestone. Understanding these figures requires looking at long-term trends, age patterns, geographic variation, and the different ways the U.S. Census Bureau and other authorities define and measure marital status. The following sections explain key definitions, sources, breakdowns, and how the share of married people has changed over decades.
Key Definitions and Measurement Methods
When analysts ask how many people are married in the United States, several definitional choices shape the answer. These include whether to count all married adults, newlyweds only, or married couples in households; whether to include same-sex married couples; and whether to rely on surveys, administrative records, or census counts. Three primary sources provide consistent, comparable estimates:
- The American Community Survey (ACS) asks respondents about their marital status annually in a large sample, producing detailed demographic breakdowns.
- The Current Population Survey (CPS) supplements provide trends on married households, household composition, and fertility.
- Marriage and divorce counts from vital records (NCHS data) track the flow of new marriages and new divorces by year.
Together, these federal data systems allow analysts to estimate how many people are married, how often people marry, and how these figures vary by age, race, education, and region.
Definitions Mattered in Practice
| Term | What It Means | Source Type |
|---|---|---|
| Married adults (18+) | Adults who report being married, regardless of household type | ACS 1-year and 5-year estimates |
| Married-couple households | Households with two spouses present, including same-sex couples | CPS ASEC, ACS |
| New marriages (annual) | Number of marriage events recorded in vital records each year | NCHS National Vital Statistics Reports |
| Marriage rate (per 1,000 unmarried adults) | Standardized measure to compare across populations and years | Calculated from CPS and ACS |
| Median age at first marriage | Age by which half of a cohort has married | CPS, NCHS trend data |
Current Estimates and Recent Trends
Recent estimates from the U.S. Census Bureau show that about 198 million adults aged 18 and older are married. This represents approximately 60 percent of all U.S. adults aged 18 and older, down from highs above 70 percent in the mid-20th century. Most married people live in married-couple households, though a growing share of adults live alone or in other arrangements. Among adults aged 25 to 54, the share married has declined more sharply than for older age groups, reflecting later marriage ages and more cohabitation. The long-term trajectory shows both a delay in first marriage and lower overall marriage prevalence compared to previous generations.
Age Patterns in Marriage
Age is strongly related to marital status in the United States. Marriage rates peak among adults in their late 20s and early 30s and decline steadily thereafter. Younger adults aged 18 to 24 have the lowest marriage rates, and many in this group are still in education or early in their careers. Among those aged 25 to 34, a substantial proportion are married, but this share has fallen over time as cohabitation and singlehood have become more common. By midlife and older age, most married adults remain married, though widowhood becomes more prevalent.
Notable Demographic and Geographic Variation
Marriage rates and the share of married adults vary considerably by demographic and geographic factors. College-educated adults and higher-income groups tend to marry at higher rates and at older ages than those without a bachelor’s degree. Racial and ethnic differences are also evident: Asian and White adults have higher shares married compared with Black and Hispanic adults, reflecting both cultural norms and structural factors such as economic stability. Regionally, marriage is slightly more common in some states in the Midwest and Mountain West, while coastal states often show slightly lower marriage rates, partly due to higher proportions of young adults and urban residents.
Comparison Snapshot
| Demographic Group | Share Married (Ages 18+) | Notes |
|---|---|---|
| All U.S. adults (18+) | ~58–60% | Estimates vary slightly by source and year |
| Adults aged 35–54 | ~65–70% | Higher stability and cumulative marriage prevalence |
| Adults aged 18–24 | ~8–10% | Lowest rates; many still in education |
| Adults aged 65+ | ~50–55% | Reflects both high marital attainment and widowhood |
| College graduates | Higher than average | Later median age at first marriage |
| Median age at first marriage (recent years) | Late 20s to early 30s | Approximate; varies by sex and group |
Long-Term Changes and What They Indicate
Over the past several decades, the proportion of U.S. adults who are married has declined, while median ages at first marriage have risen. In the 1950s and early 1960s, more than 70 percent of adults aged 18 and older were married; today that share is closer to 60 percent. These shifts are driven by multiple factors: rising educational attainment and labor force participation, greater economic independence, changing social norms around partnership and cohabitation, and increased access to reliable contraception. The decline is not uniform: adults with more education and higher incomes remain more likely to marry, and regional cultures also shape patterns. Rising age at first marriage has also contributed to a lower overall prevalence of marriage within any given year, even as lifetime marriage risk remains substantial for many.
Drivers of Change at a Glance
- Higher educational attainment and career investment, often leading to later marriage.
- Increased social acceptance of cohabitation before or instead of marriage.
- Economic factors, including housing costs and job stability, affecting household formation.
- Greater access to and use of effective contraception and family planning.
- Diverse legal and cultural recognition of relationships, including same-sex marriage.
Frequently Asked Questions
- How is marital status measured in the United States? The primary sources are the American Community Survey and Current Population Survey, which ask respondents about their marital status through self-report. Vital records (marriage licenses and divorce decrees) provide counts of events rather than point-in-time prevalence.
- How many new marriages occur each year? The U.S. typically sees between 2 million and 2.5 million marriages annually, though fluctuations occur with economic conditions and demographic changes.
- Are marriage rates falling across all groups? Rates have fallen more steeply among younger adults and some racial and ethnic groups, while remaining relatively stable among older adults and college-educated populations.
- How many people are married in the United States compared with other countries? The U.S. marriage prevalence is similar to other high-income countries, though timing of marriage tends to be later and cohabitation is increasingly common as a step before or instead of marriage.
