Workers returned to offices at a higher rate in September than they did in the year-earlier month, though attendance varied widely across major U.S. metropolian areas.
Occupancy across 10 large regions in the U.S. tracked by Kastle Systems rose to 55.4% of pre-pandemic levels in the week ended Sept. 30, up from 52.9% in the month-earlier week ended Aug. 26.
Kastle measures office occupancy against a March 2020 baseline — before widespread pandemic office closings — tracking attendance using anonymized keycard-swipe data from thousands of buildings nationwide.
The September reading was higher than the 54.1% recorded during the same week a year earlier.
New York saw the largest monthly increase, climbing to 66% of its pre-pandemic level from 53.8% at the end of August and 54.3% during the comparable week a year earlier. In Washington, D.C., occupancy rose to 52.2% from 45.8% at the end of August and was unchanged from 52.3% the prior year.
Austin moved in the opposite direction, with occupancy falling to 67.9% at the end of September from 73.7% a month earlier. Philadelphia, meanwhile, remained the lowest of the 10 markets tracked by Kastle at 42%, up from 39.5% at the end of August but below 42.6% during the comparable week a year earlier. Chicago was little changed at 56.7%, compared with 56.9% a month earlier and 57.3% a year earlier.
