Document 3: New Haven, Connecticut: Downtown New Haven, occupied by nearly 7,000 residents, has a more residential character than most downtowns. The downtown area provides about half of the city's jobs and half of its tax base and in recent years has become filled with dozens of new upscale restaurants, several of which have garnered national praise (such as Ibiza, recognized by Esquire and Wine Spectator magazines as well as the New York Times as the best Spanish food in the country), in addition to shops and thousands of apartments and condominium units which subsequently help overall growth of the city.
Document 4: New Haven, Connecticut: The American Civil War boosted the local economy with wartime purchases of industrial goods, including that of the New Haven Arms Company, which would later become the Winchester Repeating Arms Company. (Winchester would continue to produce arms in New Haven until 2006, and many of the buildings that were a part of the Winchester plant are now a part of the Winchester Repeating Arms Company Historic District.) After the war, population grew and doubled by the start of the 20th century, most notably due to the influx of immigrants from southern Europe, particularly Italy. Today, roughly half the populations of East Haven, West Haven, and North Haven are Italian-American. Jewish immigration to New Haven has left an enduring mark on the city. Westville was the center of Jewish life in New Haven, though today many have fanned out to suburban communities such as Woodbridge and Cheshire.

Document 6: Yale University: During the 1988 presidential election, George H. W. Bush (Yale '48) derided Michael Dukakis for having "foreign-policy views born in Harvard Yard's boutique". When challenged on the distinction between Dukakis's Harvard connection and his own Yale background, he said that, unlike Harvard, Yale's reputation was "so diffuse, there isn't a symbol, I don't think, in the Yale situation, any symbolism in it" and said Yale did not share Harvard's reputation for "liberalism and elitism". In 2004 Howard Dean stated, "In some ways, I consider myself separate from the other three (Yale) candidates of 2004. Yale changed so much between the class of '68 and the class of '71. My class was the first class to have women in it; it was the first class to have a significant effort to recruit African Americans. It was an extraordinary time, and in that span of time is the change of an entire generation".

Document 9: Philadelphia: Based on the similar shifts underway the nation's economy after 1960, Philadelphia experienced a loss of manufacturing companies and jobs to lower taxed regions of the USA and often overseas. As a result, the economic base of Philadelphia, which had historically been manufacturing, declined significantly. In addition, consolidation in several American industries (retailing, financial services and health care in particular) reduced the number of companies headquartered in Philadelphia. The economic impact of these changes would reduce Philadelphia's tax base and the resources of local government. Philadelphia struggled through a long period of adjustment to these economic changes, coupled with significant demographic change as wealthier residents moved into the nearby suburbs and more immigrants moved into the city. The city in fact approached bankruptcy in the late 1980s. Revitalization began in the 1990s, with gentrification turning around many neighborhoods and reversing its decades-long trend of population loss.

Document 11: New Haven, Connecticut: New Haven's economy originally was based in manufacturing, but the postwar period brought rapid industrial decline; the entire Northeast was affected, and medium-sized cities with large working-class populations, like New Haven, were hit particularly hard. Simultaneously, the growth and expansion of Yale University further affected the economic shift. Today, over half (56%) of the city's economy is now made up of services, in particular education and health care; Yale is the city's largest employer, followed by Yale – New Haven Hospital. Other large employers include St. Raphael Hospital, Smilow Cancer Hospital, Southern Connecticut State University, Assa Abloy Manufacturing, the Knights of Columbus headquarters, Higher One, Alexion Pharmaceuticals, Covidien and United Illuminating. Yale and Yale-New Haven are also among the largest employers in the state, and provide more $100,000+-salaried positions than any other employer in Connecticut.[citation needed]
