FBI NICS Background Checks by State

Reply

I used Python to clean and aggregate data and then created some basic data visualizations in Tableau to look at which state characteristics appear to have an effect on the number of background checks for firearms purchases.

There are definitely some interesting patterns. The HTML files with all the details are in the links below, however here are some highlights:

More and more NICS checks are being done every year:

02a5d0bf-de83-4113-8524-56c6af40875e

Cyclical nature of NICS checks, but overall increasing since 1998:

943b9724-68ca-4253-b3e0-d29fb941f009

Number of checks with key events:

66d6901b-3737-4569-a172-7beef88803bc

State by State:

d0717b99-83af-47a7-8b0e-55c0c9a603c8

Are you wondering what’s with Kentucky? It’s not as scary as it looks – new legislation was passed that makes certain permit holders required to do an annual background check, so in this case, checks aren’t a great proxy for purhcase rates.

Here’s another state-by-state, this time the graph colored by voting tendency:

me. a lot.

I’ve been wearing a Fitbit for more than 5 years. I took over a year of my own Fitbit sleep logs and created a Tableau Story Point to explore patterns and see if they hold any useful info! I explored activity levels (total active minutes, etc.), menstrual cycle phase and calorie burn.

I used Tableau Story Point to walk through the exploration: Check it out here.
