Methodology: The Federal Aviation Administration’s registration data contains 38,975 records for the United States for a total of 459,384 drones. For each record, we matched the zip code to its county. In the occasional case where a zip code spans multiple counties, the zip code was matched to the county with the largest population. A total of 2,049 drones could not be matched to a county due to invalid zip codes in the original dataset. For per capita calculations, we used the 2015 population estimates for the counties. Some drone owners register multiple drones, so the numbers here represent the minimum number of drones
