The largest city in New England, Boston is considered the economic and cultural center of the region, and is sometimes regarded as the unofficial "Capital of New England".

Boston city proper had a 2007 estimated population of 608,352, making it the twenty-first largest in the country. Boston is also the anchor of a substantially larger metropolitan area called Greater Boston, home to 4.5 million people and the tenth-largest metropolitan area in the country.

With many colleges and universities within the city and surrounding area, Boston is a center of higher education and a center for medicine. The city's economy is also based on research, electronics, engineering, finance, and technology—principally biotechnology. Boston ranks first in the country in jobs per square mile ahead of New York City and Washington, D.C.
