Boston Authority

Also known as: Boston Metro Authority

Boston is a upper-middle-income mid-sized city of 666,442 with home prices 1.3× the Massachusetts median.

Boston is one of those cities that manages to be simultaneously very old and very young, which is a trick not many places pull off convincingly. The median age of its residents is 33.3 years, according to Census ACS 5-Year data, which places the city firmly in the territory of graduate students, early-career professionals, and people who have recently discovered that rent is, in fact, quite high.

Population and Demographics

The city's total population stands at 666,442, distributed across 279,216 households, of which 128,433 are family households, per Census ACS 5-Year 2023 data. The racial and ethnic composition reflects a genuinely diverse urban population: 317,080 residents identify as white, 143,024 as Black, 66,500 as Asian, and 125,767 as Hispanic or Latino. The 18-to-34 age cohort numbers 253,484 people, making it the largest single age band in the city — a demographic reality that shapes everything from housing demand to the character of the city's neighborhoods on a Friday evening.

Children under 18 account for 15.1 percent of the population, or roughly 100,638 residents, which is a relatively modest share for a city of this size and speaks to the dominance of the young-professional character Census data describes.

Housing Affordability

Boston's housing market is, by any reasonable measure, expensive. The price-to-income ratio sits at 7.5, and rent consumes an average of 26.5 percent of household income, according to figures calculated from Census median income and home value data. The affordability assessment is plainly stated: the city is classified as "very expensive" and does not meet standard affordability thresholds. A price-to-income ratio above roughly 3.0 is generally considered unaffordable by housing economists; at 7.5, Boston is well past that threshold. This is not a new condition, but it is a persistent one.

Air Quality

The EPA's AQI Annual Summary for 2024 recorded 366 days of air quality monitoring in Boston. Of those, 291 were classified as "good" days and 75 as "moderate." There were zero days recorded as unhealthy for sensitive groups, unhealthy, very unhealthy, or hazardous. The maximum AQI recorded during the year was 78, which falls within the moderate range. For a dense urban environment, this is a reasonably favorable profile.

Climate

The nearest weather station with reliable long-term data is located in Jamaica Plain, approximately 2.9 miles from the city center, per NOAA ACIS records. The average annual temperature is 52.8 degrees Fahrenheit, and annual precipitation averages 49.3 inches. Boston's climate is what meteorologists call humid continental — four distinct seasons, winters that are genuinely cold, and summers that are warm enough to make the winters seem, in retrospect, not so bad.

Broadband Infrastructure

According to FCC Broadband Data Collection figures as of June 2025, 100 percent of Boston's 358,761 housing units have access to broadband service at speeds of at least 25 Mbps download and 3 Mbps upload. Coverage at the 100/20 Mbps tier is likewise 100 percent, as is coverage at the 250/25 Mbps tier. At the gigabit tier — 1,000 Mbps download and 100 Mbps upload — coverage reaches 62.5 percent of units. This places Boston among the better-served large cities in the country for broadband access, though the gap at the gigabit tier is worth noting for residents and businesses whose work depends on the fastest available speeds.

Education

Boston hosts 28 colleges and universities, per NCES IPEDS 2022 data. Among them, Boston University stands out in the College Scorecard data: it enrolls 18,248 students, carries an average SAT score of 1,480, and admits approximately 11.1 percent of applicants. In-state and out-of-state tuition are identical at $68,102 — a figure that reflects the private university model and is worth understanding clearly before applying. The completion rate is 89.3 percent, and median earnings for graduates are reported in the scorecard data.

For younger residents, the city has 59 licensed childcare centers, including Head Start programs and enrichment facilities distributed across the city's neighborhoods.

Arts and Civic Organizations

Twenty-seven arts organizations operate within Boston, per IRS Exempt Organizations data. These include the Boston Symphony Orchestra and Boston Ballet, two institutions with national and international reputations, alongside smaller organizations such as the Que Shing Chinese Music and Opera Group. The breadth of that list — from a major symphony to a community music organization — reflects the layered cultural infrastructure that a city of Boston's size and history tends to accumulate.

Ten civic service organizations are active in the city, among them Big Brothers Big Sisters of Massachusetts Bay and the Boys and Girls Clubs of Boston. The Greater Boston Chamber of Commerce, identified through the IRS Exempt Organizations Business Master File, serves as the primary organized voice of the business community.

Animal Welfare

Twenty-four animal welfare organizations operate in or near Boston, including the Massachusetts Society for the Prevention of Cruelty to Animals, one of the oldest such organizations in the country, and the New England Anti-Vivisection Society. The range of organizations reflects both the city's density and its long tradition of organized civic charity.

Zoning and Land Use

Boston's zoning framework is codified at the neighborhood level in several distinct articles. The South Boston Neighborhood District, for instance, is governed by Article 68 of the Boston Zoning Code, which establishes its own internal rules and explicitly states that where conflicts exist between Article 68 and the remainder of the Code, the provisions of Article 68 shall govern. The same article notes that zoning relief in the form of exceptions is not available except to the extent expressly provided within that article or Article 6A — a restriction that reflects the city's effort to maintain neighborhood-specific planning controls rather than relying solely on citywide variance procedures.

Banking and Financial Services

Multiple FDIC-insured banking institutions maintain branches within the city, per FDIC Institutions and Branches data. TD Bank's Copley Square Branch, located at 535 Boylston Street, is among the branches documented in that dataset. The presence of multiple national and regional banks across the city's neighborhoods reflects the financial infrastructure typical of a major metropolitan center.
