DH & I did it last year and we are both doing it again this year; neither one of us are employed. The pay is good, in our area $17.50 an hour and I think it was 50 cents a mile.
When I worked last year, everybody that I talked to was wonderful. Some people asked if I was reassessing their house and were happy when I told them "no, I work for the Census Bureau".
To all those people that don't want to answer your door, all you have to do is return your completed census form. It will do two things, you won't have anybody come to your home and you will save the government money because they won't have to sent people to your door -- over and over again.
