Following a New York newspaper's controversial decision to publish the names and address of local gun owners, state legislators are moving to make such information private, even as a Sunlight Foundation analysis shows that in a majority of states, the data are already off the public record.

This map illustrates the availability - or lack - of gun ownership data in the 50 states.

It is based on information from the federal Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), the National Rifle Association's Institute for Legislative Action, the Reporters Committee for the Freedom of the Press, as well as Sunlight's reporting. We welcome any additional information about gun laws in your area. You can email the Sunlight Foundation here:
