Most Educated Cities in America
PlainCities ranks large US cities by the share of adults holding a bachelor's degree or higher, from U.S. Census Bureau American Community Survey data, rendered live from the cities table.
Research question
Among large US cities (population 50,000 or more), which have the highest share of adults 25 and over holding at least a bachelor's degree, and how closely does educational attainment track with median household income across the same places?
Methodology
We queried the PlainCities cities table at server render time, selecting the name, state, bachelor's-degree share, population and median household income columns for every place with a population of at least 50,000 and a non-null attainment value. The query orders records by the bachelor's-or-higher share in descending order and returns the top ten. Every figure on this page is read live from that query, so the ranking refreshes whenever the underlying Census release is reingested.
Educational attainment comes from the American Community Survey 5-year estimates, Table S1501. The measure is the percentage of adults aged 25 and over who hold a bachelor's degree or higher. Restricting the base to the 25-and-over population is deliberate: it captures people who have finished their schooling rather than current undergraduates, which keeps a large state university from inflating a town's apparent attainment with students who have not yet graduated.
We apply a 50,000-resident population floor. In small places the attainment estimate rests on a modest survey sample and the Census margin of error widens accordingly, so a handful of households can swing the figure several points. Holding the field to mid-size and large cities keeps the comparison statistically sound. A separate aggregate query, run against the same filtered population, returns the count of qualifying cities and the average attainment across all of them, anchoring the top ten against the wider field.
A companion query returns the most educated large cities at a higher population floor (100,000 or more), to show that the pattern holds among the biggest cities and is not an artifact of a few affluent mid-size suburbs. Both cuts draw from one column and one definition, so the comparison is consistent. The two charts below visualize these cuts; the table lists the headline ranking row by row, each city linking to its full profile.
Every number traces back to a single source row. A practitioner can copy the SQL from this page's frontmatter, point it at a local mirror of the PlainCities database, and reproduce the exact ranking. See the methodology page for the full ETL pipeline, the Census vintage, and column lineage.

Findings
The most educated large city
The highest bachelor's-degree share among large US cities belongs to Bethesda, MD, where 87.1% of adults 25 and over hold at least a four-year degree. The cities at the top of this ranking cluster around major university systems, technology employers and professional-services economies, where a degree is effectively a job requirement and graduates concentrate.
How far above average the leaders sit
Across all 869 large cities in the dataset, the average bachelor's-or-higher share is 37.3%. The leaders run well above that line — a reminder that educational attainment is highly concentrated geographically, with a relatively small set of cities capturing a disproportionate share of degree-holders. The same concentration shows up in income: the most educated cities tend to post some of the highest median household incomes in the country, which the income column in the table makes visible row by row.
Attainment is not the same as opportunity
A high degree share signals a strong professional labor market, but it does not by itself mean a city is affordable or easy to move to — the same forces that draw degree-holders often push up rents and home prices. Each city in the table links to its full profile, where attainment sits alongside income, housing cost and poverty, so you can weigh education against the cost of living before drawing conclusions.
Why the 25-and-over base matters
The choice to measure adults aged 25 and over is not a technicality; it changes which cities rise to the top. A college town with tens of thousands of undergraduates would post a deceptively low attainment figure if students were counted, because most have not yet earned their degree. By restricting the base to people old enough to have finished their education, the measure captures the settled, working population rather than the transient student one. That is why the leaders here tend to be affluent suburbs and professional hubs rather than the towns with the most famous universities — the graduates a university produces often move elsewhere for work, carrying their degrees with them.
Education and the local industry mix
Attainment is ultimately a mirror of the local economy. Cities built around technology, research, government, finance, and healthcare demand degrees at a high rate, and the people who fill those jobs cluster nearby. Cities whose economies lean on manufacturing, logistics, agriculture, or tourism show lower attainment not because their residents are less capable but because the available work asks for different credentials. Reading the bachelor's-degree share alongside each city's median income makes that link visible: the two tend to rise and fall together, because both are downstream of the same underlying mix of industries and occupations.
What this analysis cannot tell us
Educational attainment is the share of the population aged 25 and over holding a bachelor's degree or higher, from the U.S. Census Bureau American Community Survey 5-year estimates (Table S1501). It counts the degree, not where it was earned or whether the holder works in a related field, and it says nothing about the quality of local schools — a city can have a highly educated adult population because graduates move there for work, not because it educated them. The 25-and-over base excludes current students, so college towns with large undergraduate populations can read lower than their reputation suggests. The 5-year aggregation smooths year-to-year change, and a 50,000-resident floor excludes small places where the estimate carries the widest margin of error. Attainment correlates strongly with income but does not cause it; both reflect the underlying mix of industries and occupations in a local economy.
