> As to why/how someone is "missing" on a census, I have a couple of theories...< Some people just do not want to be counted or have the government know anything about them or who lives there. I was an enumerator in an urban area for the 2000 census--we were sent out to contact everyone who did not send back the form in the mail by the deadline. In the areas I was covering there were more than a few occupied houses I visited half a dozen times or more where the people were never home at various times of day or would not answer the door for whatever reason, so many people were not counted. Some would answer the door but give no information or become abusive, so we were instructed to guess on age, race, gender, number of occupants, etc. without a name. It's no wonder there is a lot of incorrect information. It was probably the same or worse in earlier days. The only cases I saw that had their own reasons for non-disclosure were: a woman trying to hide from an abusive partner who she feared might have gone to work for the census, and a man in a bad neighborhood who was probably a drug dealer or otherwise up to no good. Some census workers have been killed. ---Pam B.
