30 years of gun sales, or graphics showing gun control effort's unintended consequences
There are download links for the author's spreadsheet (data and graphs) in both .xls and .ods forms.A couple of months ago, when I had some free time, I dipped a toe into some of the BATFE's sales data on guns. Today, having lots of free time (avoiding the shopping frenzy and distracting myself from some personal issues) I went deeper into the ATF's data and crunched some numbers. I subtracted exports and added imports, and got a slightly newer version of the report (data goes to 2015, not 2013).
I downloaded the .ods and it loaded perfectly into LibreOffice calc.
