How to prepare and behave

This is editorial guidance, not information from the employer.

Know your rights as a candidate and an employee:

The city

The job is in Boston, MA. Below is what the official statistics say about living and working there.

How Boston compares. Among the 80 largest places in Massachusetts, Boston is #1 by population, #75 for homeownership (#1 = highest), #62 for rent (#1 = cheapest), #28 for remote work (#1 = most). Its county, Suffolk County, is #1 of 14 counties for average pay ($131,280).

The place in numbers

Boston has 666,442 residents (ACS 2020–2024), about 9.5% of the population of Massachusetts. It covers 48 square miles of land, which works out to roughly 13,786 people per square mile. The median age is 33.3, 17% younger than the state median (33.3 against 40.0).

Housing

The median gross rent is $2,147 a month (rent plus utilities), 22% above the state median ($2,147 against $1,762). Over a year that is 26.5% of the median household income. US housing guidance treats housing as affordable when it takes 30% of income or less, so the typical household is under that line. The median home value is $731,700, which is 7.5 times the median household income ($97,344); a ratio above 5 usually means buying is out of reach without savings or a second income. 35.7% of households own their home, 43% below the state average (35.7% against 62.5%). A low ownership share points to a rental-heavy market with more apartments and shorter stays.

Work and pay

The Boston-Cambridge-Newton, MA-NH metropolitan area has 2,703,890 jobs in the BLS wage survey, and the median pay across all occupations is $66,620 a year, 31% above the national median ($66,620 against $50,980). The biggest occupation groups are office and administrative support (265,830 jobs, median $56,580); management (254,700 jobs, median $166,580); business and financial operations (242,960 jobs, median $102,660). The area is most specialised in life, physical, and social science (2.6 times) and architecture and engineering (1.4 times), where the share of workers is well above the national share. The best-paying groups with at least 5,000 jobs are management ($166,580) and legal ($135,160). In 2026M09 the unemployment rate of Suffolk County was 4.2%. 69.9% of residents aged 16 and over are in the labour force. The city lies in Suffolk County; its jobs, pay by industry and GDP are on the county page.

Getting around

Among workers, 32.9% drive alone, 22.6% use public transit, 13.4% walk, 21.3% work from home. 22.0% of workers commute 45 minutes or more, about the same as the state average (22.0% against 21.5%).

People and education

54.9% of adults aged 25 and over hold a bachelor's degree or higher, 16% above the state share (54.9% against 47.3%). 27.8% of residents were born outside the United States, 54% above the state share (27.8% against 18.1%). The poverty rate is 16.6%, 65% above the state rate (16.6% against 10.0%).

Climate

The warmest month is Jul, averaging 72°F (22.4°C), and the coolest is Jan at 26°F (-3.5°C). About 1,206 mm (47 inches) of precipitation falls in a year; Oct is the wettest month (123 mm) and Jan the driest (80 mm). These values come from NASA satellite-based climatology on a grid of about 50 km, so they describe the wider area, not a weather station in the city.

Nearby cities to compare

Closest cities in this guide: Winthrop Town (4 miles, rent 4% lower); Chelsea (4 miles, rent 9% lower); Everett (5 miles, rent 3% lower); Quincy (5 miles, similar rent). Rent differences are against Boston; use the Compare tab to put any two cities side by side.
