I just saw the numbers, The Bronx has the highest percentage positive for antibodies - 27.9%. None of the other boroughs have more than 20% with Manhattan being the lowest at about 17%.
After speaking to an energy company dealing with calculating changes in usage, I may have some
speculative insight into this. They are finding that energy usage changes are very dependent on the type of multi-family building. In low end apartments usage has gone up due to everyone being home, but in the higher end apartments in Manhattan the usage has actually gone down about 15% mostly due to many of the residents having laft the city to vacation homes and the like. This also lowered the density of Manhattan by quite a bit.
I wonder if the zip code map shows this too.
