In many central business districts (CBDs), job growth has occurred since the 1990s, but at a far slower rate than in non-CBD areas. Over this time, there has been a great divergence in economic performance among CBD areas, with a handful of CBD economies far outperforming the rest. Overall, CBD economies have become home to higher paying economic activities, compared with non-CBD areas, because industries comprising higher levels of “cognitive” tasks locate a higher share of jobs in CBD areas. As such, CBD performance seems to be tied to the mix of industries present in a given region’s economy.
