It's definitely region-dependent.

I grew up in an affluent suburb of Massachusetts, where guns were really uncommon.

I got stationed in Yuma, Arizona, where pretty much everyone owned guns.

Here in a suburb of Portland, OR, it's somewhere in the middle. Oregon is an interesting state.

I did mean the percentage, but it does look like the absolute number of households owning guns has very slightly declined.

I imagine it's difficult to get good numbers on ownership though as the cross section of people who would not disclose firearm ownership to the government or polling agency would also be likely to own a firearm. This is compounded by the fact that firearms last upwards of 100 years with minimal maintenance and there are healthy secondary and black markets for them.

Nope. No guns at this here house. Not since the tragic boating accident of early 2019.

What state do you live?

South Carolina.
