The following is a visualization of the communities in Massachusetts, those with populations larger than 5,000, where the percentage of Class A LTCs is the highest. A Class A License to Carry (LTC) means the license holder may carry a concealed weapon in Massachusetts.
The state keeps records on the number of Class A LTCs issued in every community in Massachusetts. This information comes from WCVB’s post from June 21. I feel this map gives a better sense of trends and proximity than WCVB’s card-style presentation.
