Chicago ViewPoint - The Urban Migration Paradigm April 2016
From 2010 to 2015 approximately 2.5 million sq. ft. was absorbed in the CBD, reflecting 43 relocations from the suburbs.
The West Loop gained 46% of the total space taken by tenants who relocated to the CBD from the suburbs, with River North absorbing 31% in the time frame. Meanwhile, 45% of the companies that relocated to the CBD vacated the North Suburban submarket.
Even though downtown is the heart of the metro area’s economic activity, the suburbs have a much larger employment footprint. The suburban workforce is about 3 million, nearly four times that of the city.
