More than half of American voters -- 52% -- say they or someone in their household owns a gun, per the latest NBC News national poll.

That's the highest share of voters who say that they or someone in their household owns a gun in the history of the NBC News poll, on a question dating back to 1999.

In 2019, 46% of Americans said that they or someone in their household owned a gun, per an NBC News/Wall Street Journal poll. And in February 2013, that share was 42%.

"In the last ten years, we've grown [10 points] in gun ownership. That's a very stunning number," said Micah Roberts of Public Opinion Strategies, a Republican polling firm that co-conducted the poll with members of the Democratic polling firm Hart Research.

"By and large, things don't change that dramatically that quickly when it comes to something as fundamental as whether you own a gun," Roberts added.

Gun ownership does fall along partisan lines, as it has for years, the poll finds.

Do you, or does anyone in your household, own a gun of any kind?

This month, 66% of Republican voters surveyed say that they or someone in their household owns a gun, while just 45% of independents and 41% of Democrats say the same.

In 2004, a March NBC News/Wall Street Journal poll found that 57% of Republicans said that they or someone in their household owned a gun, while just 41% of independents and 33% of Democrats said the same.
