Local Demographics in 10 Maps

Every city, county, zip code, and neighborhood in the US has a BestNeighborhood demographics page. Each one brings together 10 interactive maps and the numbers behind them, in five sections: population and households, housing, rent, education, and jobs. The figures come from the Census Bureau’s American Community Survey (ACS) 2020–2024 5-year estimates, the most recent release as of September 2026.

Demographics Pages and Best Neighborhoods

The demographics pages are for digging into one measure at a time: how old residents are, how many households rent, when the homes were built, and how many adults finished college. Each measure gets its own map and its own number, so it is easy to see where a single trait runs high or low.

To find the best place to live with every factor weighed at once, start with Best Neighborhoods instead. It scores every neighborhood in the US on 40 measures, including education, home age, vacancy, housing costs, and jobs, and lets you set how much each one matters to you. The Best Places to Live rankings apply the same measures to whole metro areas, cities, and towns.

What Each Demographics Page Shows

Each page opens with the area’s population and a menu that jumps to its five sections. Every map loads with a click, zooms in to show neighborhood detail, and has a colorblind-friendly setting.

Section	Maps	What the numbers show
Population and households	Household size, resident age, single-parent homes	The average number of people per household, the median age compared with the national median, and the share of households headed by a single parent
Housing	Owners and renters, vacancy, home age	The share of homes that are rented, the share owned free and clear, the vacancy rate, and the median year homes were built
Rent	Rent cost	Median monthly rent and how it ranks within the state, the share of income a typical renter spends on rent, the median home value compared with nearby places, and the parts of the area where rents run highest and lowest
Education	Bachelor’s degrees, high school graduates	The share of adults 25 and older with a bachelor’s degree or higher, and the share with a high school diploma or equivalent
Jobs	Employment	The employment rate, with unemployment mapped neighborhood by neighborhood

Below the maps, each page lists nearby places and places with a similar population, so one area can be compared with its neighbors in a click. A menu on each page links to every other BestNeighborhood page for the same area, including Walk Grade, household income, political lean, traffic noise, and internet service.

How the Largest US Cities Compare

The table shows each measure for the US as a whole, along with the highest and lowest values among the 91 US cities with at least 250,000 residents. Each city name opens that section of the city’s demographics page.

Measure	United States	Highest big city	Lowest big city
Median age	38.9	St. Petersburg, FL: 43.1	Laredo, TX: 29.9
Average household size	2.53	Santa Ana, CA: 3.81	St. Louis, MO: 1.92
Single-parent households	10.0%	Newark, NJ: 20.7%	Seattle, WA: 4.1%
Homes that are rented	34.8%	Newark, NJ: 75.6%	Chesapeake, VA: 25.6%
Vacancy rate	10.1%	Detroit, MI: 21.7%	Santa Ana, CA: 3.1%
Median year homes were built	1980	Gilbert, AZ: 2003	St. Louis, MO: 1938
Median gross rent	$1,413	Irvine, CA: $2,997	Toledo, OH: $901
Median home value	$332,700	San Francisco, CA: $1,394,500	Detroit, MI: $83,900
Bachelor’s degree or higher, adults 25+	35.7%	Irvine, CA: 70.6%	Detroit, MI: 18.1%
High school graduate or higher, adults 25+	89.6%	Irvine, CA: 96.7%	Santa Ana, CA: 66.9%
Employment rate	94.8%	Madison, WI: 97.3%	Detroit, MI: 86.0%

Big cities skew young and rent more than the country as a whole. Only 6 of the 91 have a median age above the national 38.9. In 88 of them, a larger share of homes is rented than nationwide, and renters outnumber owners in 36.

Housing age tracks when each city grew. The median home in St. Louis and Buffalo dates to 1938. In Gilbert, Arizona, and North Las Vegas, half of all homes were built in 2003 or later.

The national vacancy rate of 10.1% runs above the rate in 70 of the 91 big cities. Part of the gap comes from vacation homes, which the Census Bureau counts as vacant and which cluster outside big cities.

Where These Numbers Come From

The demographics pages and this page draw on the U.S. Census Bureau’s American Community Survey 2020–2024 5-year estimates, the most recent release available as of September 2026. BestNeighborhood updates both when the Census Bureau publishes each new release.

The big-city table uses the Census Bureau’s published figures for each city’s legal limits. The demographics pages build each figure from the neighborhoods inside an area, weighted by population, so a city’s page can differ slightly from the table. For several of the largest cities, the page describes the whole metro area rather than the city alone.

The survey reaches about 3.5 million addresses a year. Pooling five years of answers gives enough of them to map single neighborhoods. Every estimate has a margin of error, and the margin is wider for a single neighborhood than for a whole city.
