The region forms the northern arc of the U.S. northeast megalopolis and as such, Greater Boston can be described as either a metropolitan statistical area (MSA), or as a broader combined statistical area (CSA). The MSA consists of most of the eastern third of Massachusetts, excluding the South Coast region and Cape Cod; while the CSA additionally includes the municipalities of Manchester (the largest city in the U.S. state of New Hampshire), Providence (the capital of the U.S. state of Rhode Island), Worcester, Massachusetts (the second largest city in New England), as well as the South Coast region and Cape Cod in Massachusetts. Greater Boston's most impactful contributions to human civilization involve the region's higher education institutions and sports culture. Greater Boston also constitutes a region influential upon American history and industry. The region and the state of Massachusetts are global leaders in biotechnology, engineering, higher education, finance, and maritime trade.  - A single tax is a system of taxation based mainly or exclusively on one tax, typically chosen for its special properties, often being a tax on land value.

Today it is an affluent residential town noted for its excellent public schools, with its students consistently ranking in the state's top ten test results in English and math. The population was 6,520 at the 2010 census.   - In the United States, a metropolitan statistical area (MSA) is a geographical region with a relatively high population density at its core and close economic ties throughout the area. Such regions are neither legally incorporated as a city or town would be, nor are they legal administrative divisions like counties or separate entities such as states. As such, the precise definition of any given metropolitan area can vary with the source. A typical metropolitan area is centered on a single large city that wields substantial influence over the region (e.g., Chicago or Atlanta). However, some metropolitan areas contain more than one large city with no single municipality holding a substantially dominant position (e.g., DallasFort Worth metroplex, Norfolk-Virginia Beach (Hampton Roads), RiversideSan Bernardino (Inland Empire) or MinneapolisSaint Paul).  - Frederick Fiske Warren ( 2 July 1862 -- 2 February 1938 ) was a successful paper manufacturer , fine arts denizen , United States tennis champion of 1893 , and major supporter of Henry George 's single tax system which he helped develop in Harvard , Massachusetts , United States , in the 1930s .

The United Nations defines the essential features of population and housing censuses as "individual enumeration, universality within a defined territory, simultaneity and defined periodicity", and recommends that population censuses be taken at least every 10 years. United Nations recommendations also cover census topics to be collected, official definitions, classifications and other useful information to co-ordinate international practice.  - Beacon Hill is a historic neighborhood in Boston, Massachusetts.

The state is named for the Massachusett tribe, which once inhabited the area. The capital of Massachusetts and the most populous city in New England is Boston. Over 80% of Massachusetts' population lives in the Greater Boston metropolitan area, a region influential upon American history, academia, and industry.
