I wish I had more data on it, but I've seen many different sources saying the same thing, but the number has more closely approximated 2.5% here, and so I'm wondering if there is discrepancy, or this is within the range of statistical accuracy of one or both.
(OP) its hard to have an exact percentage because it's (crude) observation - I could totally go with 2.5%. The number is in the low single digits for sure, but definitely higher than a rounding error (or a null-hypothesis). Whatever the number is, it's high enough to impact the people that have to interact with lots of other people - they feel it, which is really what I was getting at.
