Their analysis separates workers into three classes, derived from Florida’s research: the “creative class” of knowledge workers who make up about a third of the U.S. workforce (people in advertising, business, education, the arts, etc.); the “service class,” which makes up the largest and fastest growing sector of the economy (people in retail, food service, clerical jobs); and the “working class,” where blue-collar jobs in industries like manufacturing have been disappearing (this also includes construction and transportation).
…these maps show that those workers tend to cluster in the same communities. About three-quarters of the region’s “creative class” lives in a census tract where their neighbors are primarily creative-class workers, too. That means your lawyers, doctors, journalists and lobbyists live together in parts of town far from the people who pour their coffee.
This also means that their evolving preferences — to live downtown, or close to the red line, or around Rock Creek Park — shape the city for everyone else.
