We almost got missed. We had received a notice of visit on our door, and it said we would get another visit. I called the number on the form after a few days when we didn't hear anything back. The guy asked our address, and then said he'd already taken care of it. I asked for some clarification since I knew we hadn't responded. I was told that our neighbor told him our house was a vacation rental/second home. Wrong, we're permanent residents.
I like the idea of a direct contact, but if they are going to so easily assume a house is a second home then we are going to have a huge under count.
DeFuniak is having a mail it back festival for the census, and they didn't even send forms to homesteaded houses in SoWal.
Make sure you get counted, it's important for everything from BCC districts to schools and getting the number of hospital beds available.
