Greater Boston is themetropolitan region ofNew England encompassing the municipality ofBoston, the capital of theU.S. state ofMassachusetts and the most populous city in New England, and its surrounding areas, home to 4,941,632. The most stringent definition of the region, used by the Metropolitan Area Planning Council, consists of most of the eastern third of mainland Massachusetts, excluding theMerrimack Valley and most ofSoutheastern Massachusetts, though most definitions (including theU.S. Census definition) include much of these areas and portions of southernNew Hampshire.[2]
While the city of Boston covers 48.4 square miles (125 km2) and has 675,647 residents as of the 2020 census, the urbanization has extended well into surrounding areas and the Combined Statistical Area (CSA in the rest of the document), which includes theProvidence, Rhode Island,Manchester, New Hampshire,Cape Cod andWorcester areas, has a population of more than 8.4 million people, making it one of the most populous such regions in the U.S.
Some of Greater Boston's most well-known contributions involve the region'shigher education and medical institutions. Greater Boston has been influential upon Americanhistory andindustry. The region and the state of Massachusetts are global leaders inbiotechnology,artificial intelligence,[2]engineering,higher education,finance, andmaritime trade.[3]
Greater Boston isranked tenth in population among US metropolitan statistical areas, home to 4,941,632 people as of the2020 United States census, andsixth among combined statistical areas, with a population of 8,466,186. The area has hosted many people and sites significant toAmerican culture and history, particularlyAmerican literature,[4]politics, and theAmerican Revolution.
Plymouth was the site of the first colony in New England, founded in 1620 by thePilgrims, passengers of theMayflower. In 1692, the town ofSalem and surrounding areas experienced one of America's most infamous cases ofmass hysteria, theSalem witch trials.[5] In the late 18th century, Boston became known as the "Cradle of Liberty"[6] for the agitation there that led to theAmerican Revolution.
The Greater Boston region has played a powerful scientific, commercial, and cultural role in the history of the United States. Before theAmerican Civil War, the region was a center for theabolitionist,temperance,[7] andtranscendentalist[8] movements.[9] In 2004, Massachusetts became the first U.S. state to legally recognizesame-sex marriage as a result ofthe decision of theMassachusetts Supreme Judicial Court in Boston.[10] Many prominent American political dynasties have hailed from the Boston region, including theAdams andKennedy families.
Harvard University inCambridge isthe oldest institution of higher learning in the United States, founded in 1636,[11] with the largestfinancial endowment of any university,[12] and whoseLaw School has spawned a contemporaneous majority ofUnited States Supreme CourtJustices.[13]Kendall Square in Cambridge has been called "the most innovative square mile on the planet", in reference to the high concentration ofentrepreneurialstart-ups and quality of innovation which have emerged in the vicinity of the square since 2010.[14][15] Both Harvard University and theMassachusetts Institute of Technology, also in Cambridge, have been ranked among the most highly regardedacademic institutions in the world.[16]
The most restrictive definition of the Greater Boston area is the region administered by the Metropolitan Area Planning Council.[17] The MAPC is a regional planning organization created by theMassachusetts legislature to oversee transportation infrastructure and economic development concerns in the Boston area. The MAPC includes 101 cities and towns that are grouped into eight subregions. These include most of the area within the region's outer circumferential highway,I-495. In 2013, the population of the MAPC district was 3.2 million, which was 48% of the total population of Massachusetts,[18] in an area of 1,422 square miles (3,680 km2),[17] of which 39% is forested and an additional 11% is water, wetland, or other open space.[19]
The cities and towns included in this definition are:[20]
Two definitions are used by theUnited States Census to define theBoston–Cambridge–Newton, MA–NH Metro Area orBoston–Cambridge–Newton, MA–NH Metropolitan NECTA, which is defined as aNew England City and Town Area.[21][22] The metro area definition is based on counties, while the NECTA definition is based on city and town boundaries. Counties included in the county-based definition include:[21]
The NECTA definition includes all of the communities from the MAPC definition, as well as theMerrimack Valley communities, parts of southernNew Hampshire (northward toMilford andHampton, and theTaunton area.

The widest definition of the metropolitan area based on commuting patterns, is defined by the U.S. Census as theBoston–Worcester–Providence combined statistical area. This area consists of the following counties in Massachusetts, Rhode Island, and New Hampshire:[23]

The total population for the extended region was estimated at 8,466,186 at the 2020 census.[citation needed]

Greater Boston has a sizable Jewish community, estimated at between 210,000 people,[39][40] and 261,000[41] or 5–6% of the Greater Boston metro population, compared with about 2% for the nation as a whole. Contrary to national trends, the number of Jews in Greater Boston has been growing, fueled by the fact that 60% of children in Jewish mixed-faith families are raised Jewish, compared with roughly one in three nationally.[39] The 2020 PRRI Atlas found that 35% of the Boston metro area identified as Protestant while 26% identified as Catholic.[42]
The City of Boston also has one of the largestLGBT populations per capita. It ranks fifth of all major cities in the country (behindSan Francisco, and slightly behindSeattle,Atlanta, andMinneapolis), with 12.3% of the city identifying as gay, lesbian, or bisexual.[43]
