New Haven, According to a census of 1 July 2012, by the Census Bureau, the city had a population of 130,741. New Haven was founded in 1638 by English Puritans, and a year later eight streets were laid out in a four-by-four grid, creating what is commonly known as the "Nine Square Plan". New Haven is the home of Yale University. The university is an integral part of the citys economy, being New Havens biggest taxpayer and employer. Health care, professional services, financial services, and retail trade also help to form an economic base for the city. The city served as co-capital of Connecticut from 1701 until 1873, when sole governance was transferred to the more centrally located city of Hartford. New Haven has since billed itself as the "Cultural Capital of Connecticut" for its supply of established theaters, museums, and music venues. New Haven is also the birthplace of George W. Bush, the 43rd President of the United States. New Haven had the first public tree planting program in America, producing a canopy of mature trees that gave New Haven the nickname "The Elm City".
