A typical rental in Durham costs $1,761 a month with utilities, above the national median of $1,571. Locally, though, rents here are lower than in the wider Boston area ($2,051). Rents are up $675 a month from 2006–10, a 62% jump, roughly in step with the nation. Rent takes 42.3% of the typical renter's income, well over the 30% mark often used to define affordable rent, so many renters here are stretched.

Unemployment in Durham runs below the national rate: 3.9% of the labor force was out of work and looking, against 5.4% nationally. Unemployment has fallen 2.9 points since 2006–10, in line with the national trend. Because the Census pools five years of responses (2020–24), these rates smooth over short swings and lag the current job market.

About these numbers

Every figure on this page is a BestNeighborhood calculation from the Census Bureau's American Community Survey (ACS), built up from the Census block groups that make up Durham. Each ACS 5-year release pools five years of responses; this page shows the last 15 releases, 2006–10 through 2020–24. Neighboring releases share four of their five years, so they move gradually and small changes between them are within the survey's margin of error; in small places the lines can jump from one release to the next for the same reason. The maps show the same measures for each neighborhood, ranked against the whole country.
