Not true at all. Virtually every head of household in 1700 had a "firelock" of some kind. It was often the case that he was required to bring it to church every Sunday. General Gage confiscated every gun in Boston beginning in 1768. By some contemporary accounts this was in the thousands, and do remember that the total population of the town back then was under 20,000 souls, exclusive of Redcoats. The famous foray to Concord in April of 1775 was to confiscate a large amount of powder, muskets and at least one cannon stored there.

1 in 20? 2 in 20 is that number heads of households, which was a census calcuation. Do you also have median income figures?
I was talking more about the horse comment, which median income also figures into.
“General Gage confiscated every gun in Boston beginning in 1768.”
Which is why the Colonials rushed to the Trenton Armory get muskets and defend the armory.
