A New Map Found Just 13% of Working-Age Householders Married in One Detroit Area, While Some Suburbs Hit 79% and Reveal a Stark Family Divide

A report published by the New York Post on October 13, 2026, highlighted a striking difference in American family life: in one Detroit area, just 13% of householders between the ages of 15 and 64 were married. The New York Post’s original report examined research identifying communities where marriage is relatively uncommon and others where married households remain the norm. The findings suggest that where Americans live can coincide with dramatically different patterns of marriage and family formation.

The Detroit figure does not mean that only 13% of the city’s entire population is married, nor does it describe every household in the area. Instead, it measures the marital status of householders within a specific geographic unit used for statistical analysis. That distinction matters because the study also identified suburban communities where approximately three-quarters of working-age householders were married.

The Research Behind America’s Marriage Map

The findings come from Marriage Deserts: Mapping America’s Family Divide, a report by Chris Bullivant and Ken Burchfiel of the Institute for Family Studies. The original research report maps where married householders and married-parent households are relatively common or uncommon across the United States. Rather than examining one city in isolation, the researchers compared communities across multiple states and metropolitan regions.

The researchers used geographic units called Public Use Microdata Areas, or PUMAs, which generally contain between 100,000 and 200,000 people. These areas make it possible to distinguish neighborhoods within large cities while still creating manageable units for demographic comparisons. The analysis draws on Census-based information, including American Community Survey microdata, to examine how family arrangements vary across these locations.

What Researchers Mean by a Marriage Desert

The report uses the term marriage desert for a PUMA where fewer than 33% of householders ages 15 to 64 are married. At the other end of the spectrum, a marriage garden is an area where at least 61% of householders in that age range are married. These labels identify the lowest and highest portions of the distribution rather than suggesting that every community belongs neatly to one category.

Among the 10 areas with the lowest marriage shares, the percentages ranged from 13% to 17%. In the 10 areas with the highest shares, they ranged from 74% to 79%. The difference between those extremes exceeds 60 percentage points, showing just how sharply marriage rates can vary between individual American communities.

Married Adults and Married Parents Are Two Different Measurements

The study examines a second measure that focuses specifically on households containing children. Instead of asking whether a householder is married, this measure calculates what proportion of households with children are headed by married couples. The distinction allows researchers to separate places where marriage is uncommon among working-age householders from places where married-parent households are especially uncommon.

That distinction produces a different set of results from the general marriage rankings. Some communities have relatively low marriage rates overall but still have a much higher share of married couples among households with children. Other locations have low percentages on both measures, creating a more pronounced divide in how families are structured across neighboring communities.

The Gap Between the Lowest and Highest Rankings Is Striking

The 10 areas with the lowest shares of married householders showed a range of 13% to 17%, while the highest-ranking areas reached 74% to 79%. In practical terms, marriage was relatively uncommon among householders in the first group but much more prevalent in the second. The contrast challenges the idea that a single national average adequately describes how Americans organize their lives.

These figures also demonstrate why the report focuses on geographic differences rather than presenting one number for the entire country. A community’s position on the map can look very different from that of another area several miles away. The rankings reveal an uneven distribution of marriage, although they do not explain what caused those differences.

Married-Family Deserts Show an Even More Specific Divide

When the researchers examined households with children, the lowest-ranking areas had married-couple households accounting for approximately 18% to 26% of such households. In the highest-ranking married-family gardens, that share reached approximately 87% to 89%. The comparison highlights an especially wide gap between places where married parents are relatively uncommon and places where they account for the overwhelming majority of households raising children.

The report defines married-family deserts using a threshold below 52% of households with children being headed by married couples. Married-family gardens, by contrast, have shares of at least 79%, with the top 10 individual areas reaching the higher 87% to 89% range. These categories measure the prevalence of married-parent households, not the quality of individual families or the circumstances of every child living in those places.

Detroit Is Not the Only City Appearing in the Findings

Detroit’s 13% figure represents the most extreme end of the study’s marriage rankings, but other major metropolitan areas also appear in the results. In its independent report on the Institute for Family Studies research, Deseret News identified low-marriage areas in Detroit, Milwaukee, Cleveland, Washington, D.C., St. Louis and Columbus. Several areas outside Detroit had marriage shares of approximately 14% or 15%.

The report also identifies communities where marriage and married-parent households are both relatively uncommon, including parts of Atlanta, Baltimore, Chicago, Cleveland, Detroit, Los Angeles, Newark, New York, Philadelphia and Washington, D.C. These overlapping areas illustrate that the findings extend beyond one striking statistic. The strongest differences appear at the neighborhood and regional level rather than uniformly across entire cities.

New York and Dallas-Fort Worth Represent Opposite Extremes

The researchers also grouped neighboring statistical areas together to identify larger concentrations of communities with similar marriage patterns. Their largest grouped marriage desert was in Lower Manhattan and Brooklyn, encompassing more than 686,000 householders ages 15 to 64. The largest grouped marriage garden was in the suburbs of Dallas-Fort Worth, where the corresponding population of householders was approximately 636,000.

These totals refer to the people living within the grouped areas, regardless of whether they were married. They should not be confused with the number of married couples or families with children. Even so, the findings suggest that the differences between marriage deserts and marriage gardens can extend across substantial portions of metropolitan regions rather than appearing only in isolated neighborhoods.

The Family Divide Also Appears Across the New York Region

The report’s analysis of households with children identifies another important contrast along the East Coast. The largest grouped married-family desert was in Manhattan and the Bronx, encompassing 178,144 households with children. By comparison, the largest grouped married-family garden stretched across suburban areas between Washington, D.C., and Philadelphia, covering approximately 386,000 households with children.

This contrast is notable because the areas sit within a broader region connected by employment, transportation and housing markets. Yet the proportions of households with children headed by married couples differ substantially between the urban and suburban groupings. The findings show that sharply different family arrangements can exist within relatively close geographic proximity, although the map itself cannot determine why households are distributed that way.

Some Areas Have Low Marriage Rates but More Married Parents

The research does not treat low marriage rates and low married-family rates as interchangeable. In certain communities, including parts of Manhattan, Brooklyn, Washington, D.C., and Los Angeles, marriage is relatively uncommon among householders overall, but married couples account for a larger share of households with children. The report suggests that this pattern may reflect people marrying later in life or before having children.

The researchers use the term delayed-marriage deserts to describe this possible pattern. However, they explicitly present the explanation as a hypothesis that requires additional research, rather than an established finding about why people in those communities marry. The distinction reinforces the need to look beyond general marriage statistics when examining family life.

Census Data Shows a Broader National Shift

The geographic differences identified in the report sit within a larger national change in household composition. According to the U.S. Census Bureau’s 2025 estimates on America’s families and living arrangements, married-couple households accounted for 47% of all American households in 2025, compared with 66% in 1975. That means married-couple households no longer represented a majority of all U.S. households.

The Census Bureau also found that the share of married-couple households containing their own children under age 18 declined from 54% in 1975 to approximately 37% in 2025. Separately, the percentage of all families living with their own children under 18 fell from 54% to 39% over the same period. These measures show a long-term change in marriage and household composition, although they do not establish that every American community has followed the same trajectory.

Living Arrangements and the Timing of Marriage Have Changed

Other Census Bureau estimates help explain the broader context behind these changes. In 2024, approximately 64% of U.S. households qualified as family households, down from 79% about 50 years earlier, according to a separate Census Bureau release. The bureau defines a family household as one containing at least one person related to the householder by birth, marriage or adoption, meaning the category is broader than households headed by married couples.

The same release counted 38.5 million one-person households in 2024, representing 29% of all U.S. households, compared with 19% about 50 years earlier. It also reported that 34% of adults ages 15 and older had never married in 2024. These figures illustrate how household arrangements and marriage patterns have diversified over time, but living alone or never having married does not, by itself, establish whether someone has children or participates in a family network.

Long-Term Data Shows Fewer Children Living With Married Parents

Research by the Pew Research Center also documents the broader change in family arrangements. Its 2026 analysis of how the United States has changed over the past 50 years found that the share of adults who were currently married declined from 69% in 1970 to 50% in 2024. The analysis also found that 63% of children under 18 lived with two married parents in 2024, down from 82% in 1970.

The shift has not been identical across demographic groups. In 2024, Pew found that 80% of children whose parents had at least a bachelor’s degree lived with two married parents, compared with 47% of children whose parents had not completed high school. These figures provide additional context for the geographic differences identified in the Institute for Family Studies report, while showing that the national picture also varies considerably by education.

Why the Findings Do Not Tell the Whole Story About Families

The phrase nuclear family generally refers to a parent or parents and their children, but the statistics in the report use narrower, specific definitions based on marital status and household composition. For example, the married-parent measure does not count an unmarried couple as a married couple, even if both partners are raising children together. Likewise, it does not mean that children in households outside the married-parent category lack support, stability or strong relationships.

The distinction is important when interpreting language suggesting that traditional families are disappearing. The report documents where married couples are more or less common, but it does not measure every form of family support, the quality of relationships or the individual experiences of parents and children. Its findings are best understood as a picture of household structure rather than a complete assessment of family well-being.

Neighborhood Effects Matter, but Marriage Rates Are Not Proof of Cause

The Institute for Family Studies argues that these geographic differences deserve attention because family structure is associated with broader social and economic outcomes. Separate research by Harvard economist Raj Chetty and his collaborators, published through Opportunity Insights, has examined how the neighborhoods where children grow up can affect their prospects for upward economic mobility. That work supports the importance of studying place, but it does not establish that a community’s marriage rate alone determines the opportunities available to its children.

The Institute for Family Studies report also makes clear that its analysis is descriptive and does not seek to prove causal relationships between marriage rates, household composition and economic or social outcomes. Its maps identify patterns that may help guide additional research, but they cannot establish whether changes in income, housing, education, migration or other factors produced those patterns. Treating the findings as a definitive explanation for family change would go beyond what the research demonstrates.

Culture and Housing Affordability Remain Possible Factors

In separate reporting by Fox News, researcher Ken Burchfiel discussed how local culture and the practical challenges of buying a home and raising children may affect family formation. The Fox News report on the study noted the contrast between urban areas with low marriage shares and suburban communities where married-parent households are much more prevalent. Burchfiel also observed that a high salary does not necessarily make homeownership or raising a family affordable in an expensive city.

Those comments offer possible explanations for the patterns, rather than proof that any one factor is responsible for the results. The Institute for Family Studies did not set out to measure the individual effects of housing prices, income levels, cultural expectations or residential moves. Determining why marriage and married-parent households concentrate in some places would require research beyond the geographic comparisons presented in the report.

The Biggest Takeaway Is How Unevenly Family Life Is Distributed

The new research presents two contrasting realities: in a few American areas, married householders account for fewer than one in five working-age householders, while in others they represent roughly three-quarters or more. The gap is also visible among households with children, where married couples account for only about one-fifth to one-quarter of households in some areas but nearly nine in ten in others. These differences help explain why national statistics alone cannot capture the full range of American family arrangements.

The word disappearing therefore needs context. National data shows that married-couple households and households with children have become less prevalent over several decades, but the 2020-based geographic analysis does not demonstrate that marriage is disappearing from every community or that the patterns are worsening in each of the areas identified. What it reveals is a country where family structures differ sharply by location, leaving researchers with a clearer map of the divide but more questions to answer about how and why it developed.
