This map shows where gun dealers outnumber Starbucks locations across the US

On October 1, a gunman killed at least 59 people and injured 489 others on the Las Vegas Strip in the deadliest mass shooting in modern United States history. The shooter, identified as Stephen Paddock, open fired from the 32nd floor of the Mandalay Bay Resort and Casino into a crowd of thousands below who were attending a country music festival.

A law enforcement official said on Wednesday that in the past year Paddock bought 33 guns, most of them rifles. Under federal law, gun stores are not required to report multiple rifle purchases to the Bureau of Alcohol, Tobacco, Firearms, and Explosives (unless they are in Arizona, California, New Mexico, and Texas, and that's only for certain rifles).

After more than 1,400 mass shootings over the past five years, the Las Vegas massacre has again put a spotlight on American gun culture. As of December 2015, there are 64,747 licensed gun dealers across the country.

A mapping project by the data visualization company 1point21 Interactive puts that figure into perspective by comparing it to something many Americans know and love: Starbucks.

When users enter a zip code, the tool - called "Firearms + Frappuccinos" - maps the locations of gun dealers (in pink), mass shootings (in yellow), and Starbucks (in green), and shows totals for each. The gun shop location data comes from the ATF, while the Starbucks locations were provided by open data company Socrata. Mass shootings are defined as events when four or more people are shot and/or killed. All of the data is from 2015.
