With so many people working from home lately, there's an awful lot of empty office space right now.
Based on a weekly analysis from the office security company Kastle Systems, Dallas-Fort Worth office buildings are just barely one-third full.
Specifically, just over 35% for the week of January 20th. And that's the best on Kastle's list.
Houston is slightly lower, a fraction over 33%.
The worst on list is Washington DC with just 10% occupancy.
The barometer is based on daily security swipes of Kastle building access controls from their top ten cities.
