The trend is expected to continue, after the supreme court ruling earlier this year overturning strict limits on public gun-carrying

An estimated 6 million American adults carried a loaded handgun with them daily in 2019, double the number who said they carried a gun every day in 2015, according to a new study published in the American Journal of Public Health.

The new estimates highlight a decades-long shift in American gun ownership, with increasing percentages of gun owners saying they own firearms for self-defense, not hunting or recreation, and choosing to carry a gun with them when they go out in public, said ​​Ali Rowhani-Rahbar, a professor of epidemiology at the University of Washington, and the study’s lead author.
