The nation’s largest and most historically prominent cities tend to have highly educated sectors among their populations, and within those cities, certain ZIP codes – which generally don’t correspond to town or city boundaries – have concentrations of college graduates and those holding advanced degrees.
Using census data, 24/7 Wall St. determined the percentage of adults 25 years and over in ZIP codes across the country with at least a bachelor’s degree. Not surprisingly, it found that Washington, D.C., Boston, Chicago, San Francisco, and New York all had numerous ZIP codes ranking among the top 50 for college grads, making them among the best educated towns in the country.
However, the country’s most educated ZIP codes aren’t necessarily located in or around those cities. In fact, 22 of the top 50 are not within striking distance of the 10 cities with the highest percentage of college graduates – and of those 10 cities, only four (San Francisco, Washington D.C., Atlanta, and Boston) include or are near ZIP codes that are among the most educated in the country.

While higher education is certainly associated with higher incomes, the percentage of college-educated residents in a given location is not as strong an indicator of wealth as might be imagined. A postgraduate degree strengthens the correlation. One ZIP code in Boston can boast of great erudition, with 94.6% of its population holding undergraduate degrees – the highest percentage in the country – and 33.7% having earned an advanced degree, but its median household income is only $57,989. (See how the U.S. compares to the most educated countries in the world.)
At the same time, one ZIP code in San Francisco ranks a relatively modest 50th in college education (with 85.2% of the population having a bachelor degree and 50.2% holding graduate degrees) – but the median household income is $250,000, the highest in the country.

Methodology
To determine America’s most educated ZIP codes, 24/7 Wall St. reviewed five-year estimates of the percentage of adults 25 years and over with at least a bachelor’s degree from the U.S. Census Bureau’s 2020 American Community Survey.
We used ZIP Code Tabulation Areas – a Census geography type that defines areal representations of United States Postal Service ZIP codes – and refer to Census ZCTAs as ZIP codes.
ZIP codes were excluded if bachelor’s degree or higher attainment rates were not available in the 2020 ACS, if the ZIP code’s 25 and older population was less than 1,000, or if the sampling error associated with a ZIP code’s data was 15% or greater.
Additional information on the percentage of adults 25 years and over who have a graduate or professional degree; median household income; estimated unemployment rates for the 16 and older population in the civilian labor force; and population figures are also five-year estimates from the 2020 ACS.
The Average American Is Losing Their Savings Every Day (Sponsor)
If you’re like many Americans and keep your money ‘safe’ in a checking or savings account, think again. The average yield on a savings account is a paltry .4% today, and inflation is much higher. Checking accounts are even worse.
Every day you don’t move to a high-yield savings account that beats inflation, you lose more and more value.
But there is good news. To win qualified customers, some accounts are paying 9-10x this national average. That’s an incredible way to keep your money safe, and get paid at the same time. Our top pick for high yield savings accounts includes other one time cash bonuses, and is FDIC insured.
Click here to see how much more you could be earning on your savings today. It takes just a few minutes and your money could be working for you.
