History and Background

Newhaven Aerial green.jpg

New Haven is the second-largest municipality in Connecticut by population, after Bridgeport, with a core population of 129,779 people as of the 2010 Census. "New Haven" may also refer to the Greater New Haven Region, which has roughly 500,000 to 900,000 inhabitants depending on the measure that is used.

The City of New Haven website, at this page, has a detailed history of the city. Please also see our page on the City Beautiful Movement in New Haven.

New Haven had the first public tree planting program in America, producing a canopy of mature trees (including some large elms) that gave New Haven the nickname "The Elm City". Regarding this tree planting program, it is worth noting that Charles Dickens highlighted its effects when visiting New Haven in 1842. His words still ring true today, particularly the last line of this paragraph, which suggests that, relative to other American cities, New Haven combines the trappings of a larger, cosmopolitan city with the pleasures of a smaller and more orderly town of tree-lined streets:

"New Haven, known also as the City of Elms, is a fine town. Many of its streets (as its ALIAS sufficiently imports) are planted with rows of grand old elm-trees; and the same natural ornaments surround Yale College, an establishment of considerable eminence and reputation. The various departments of this Institution are erected in a kind of park or common in the middle of the town, where they are dimly visible among the shadowing trees. The effect is very like that of an old cathedral yard in England; and when their branches are in full leaf, must be extremely picturesque. Even in the winter time, these groups of well-grown trees, clustering among the busy streets and houses of a thriving city, have a very quaint appearance: seeming to bring about a kind of compromise between town and country; as if each had met the other half-way, and shaken hands upon it; which is at once novel and pleasant."

The City of New Haven encompasses the entire Town boundary, as defined by the State of Connecticut. New Haven is recognized as a "Place" (city) and as a "County Subdivision" (town) by the U.S. Census Bureau. The municipality has an area of 20.3 square miles, of which 18.9 square miles is land, and 1.4 square miles is water. The city is the home of Yale University and Yale-New Haven Hospital, the two largest employers within the region. Health care, professional services (legal, architectural, marketing, engineering), financial services, manufacturing, and retail trade form the basis of the local economy.
