Downtown workforce grows 20% in decade Wednesday, April 11, 2007 By Elwin Green, Pittsburgh Post-Gazette The number of people working Downtown has grown by more than 20 percent in the past decade, according to a new study by the Pittsburgh Downtown Partnership. The results of the organization's Downtown Worker Profile Study show that in 2006, 137,000 people worked Downtown, a 22.7 percent increase since 1996, when the total was 111,557. The PDP definition of Downtown includes five census tracts -- the Golden Triangle, the North Shore, the South Shore, Uptown and the Strip. Service businesses, including entertainment venues, and financial businesses each employed about one-third of the Downtown workforce, the study said.
