FYI: The economy is tanking citywide, but it’s a deeper fall for some than others, according to a new Community Service Society analysis of federal employment data for New York City. Unemployment rates are highest among 20 to 24 year olds (15.7 percent in 2002, up from 10.6 percent in 2000) and African Americans of all age groups (11 percent in 2002, up from 7.6 percent in 2000). Similarly, blue-collar workers fill the ranks of the unemployed, representing 30 percent of the city’s jobless, more than twice that of professional and technical workers, who represent a collective 13 percent. And while blacks and Latinos each make up about 24 percent of the labor force, they represent 32 and 28 percent, respectively, of the city’s unemployed. [2/28]
