If they can't make it there... ...a new study examining trends in joblessness in the city since 2000 suggests that by 2003, nearly one of every two black men between 16 and 64 was not working. The study, by the Community Service Society, a nonprofit group that serves the poor, is based on data from the federal Bureau of Labor Statistics and focuses on the so-called employment-population ratio - the fraction of the working-age population with a paid job - in addition to the more familiar unemployment rate, the percentage of the labor force actively looking for work. Don't hold your breath for Bloomberg to take the chance to come out for a bold job creation program - or for New York Democrats to pressure him to.
