Josh Katz, Margot Sanger-Katz, and Kevin Quealy report A Detailed Map of Who Is Wearing Masks in the U.S.:
In some American neighborhoods, it’s hard to spot even one person outside without a face covering. In others, your odds of seeing many maskless people are quite high.
Public health officials believe that face coverings can substantially slow transmission of the coronavirus, which is spreading rapidly in many states. But face coverings work best if they are adopted widely, and that is not the case everywhere. The accompanying map shows the odds of whether, if you encountered five people in a given area, all of them would be wearing masks.
Our data comes from a large number of interviews conducted by the global data and survey firm Dynata at the request of The New York Times. The firm asked a question about mask use to obtain 250,000 survey responses between July 2 and July 14, enough data to provide estimates more detailed than the state level. (Several states have imposed new mask requirements since the completion of these interviews.)
