The chart above is from the FBI. It shows the number of background checks done every month for the last two years. These background checks are one of the best ways to see how many guns were sold. Note that in every month of the past year, gun sales (as determined by background checks) was higher than in the same month the previous year.
This is not a good thing in a nation that has three mass shootings every two days (about 1.5 per day), and is again on track to record more than 40,000 gun deaths for this year.
NOTE -- the figures for gun sales are probably even higher, since many sales do not require a background check be done.
