Please people, specify landline/copper(POTS-Plain Old Telephone System) versus VOIP. To many, a VOIP phone is a 'landline', so it's confusing and meaningless to some of the discussion.
Plus, you can have a 'traditional' phone/handset with/with-out multiple extensions, just like in the 'old days'- one that anyone who didn't know how you are connected, would likely call it a 'landline' - but it could be connected only to your cell phone via Bluetooth - no copper
or VOIP.

And if you use your cellphone to make calls over WiFi, you are using VOIP technology, so is your cellphone now a 'landline'?
Previously, we had VOIP, and a fixed wireless connection for our internet - where is the 'land' in that? No, it's VOIP connected to a standard phone base.
I'm sure that's true. I asked Bard how many homes in the US still have landline phones and got this:
According to the CDC's National Center for Health Statistics, 28.7% of U.S. households had a landline phone in 2022.
That number seemed high to me - but it falls into the above. That was a survey, and the wording is important. It apparently lumps POTS and VOIP together:

Based on the Centers for Disease Control (CDC)’s 2022 biannual National Health Interview Survey of 15,000 U.S. households, 70.7% of American households were considered “cellular phone only.” Considering that those who answer these types of surveys may not make a clear distinction between actual POTS or a VoIP system that provides a similar user experience, the percentage [of "cellular phone only"] is likely a lot higher.
I found the source CDC report, and it actually asks "do you have a working phone in the house that is not a cell phone" - so that definitely would include VOIP.
I have not yet found a good source for the number of residential POTS lines. Some businesses keep them for legacy equipment.
