When I was a teen, I lived in a house that had at most about 7 or 8 people in a one bedroom, 4 rooms total. There were about 3 or 4 adults, and about 3 or 4 children. That's nothing new in my family, we are poor and have always stacked up like that. Several times we had 4-6 people in a 3 room shotgun. Betta believe, if a census was conducted about that time, some of us didn't get counted because it was illegal or against the ordinance to have that many people in such a small quarters. So I understand the fear. And if you are an illegal immigrant, perhaps staying with legal relative in the in the US, they may have the same or similar fear about filling out the US census. This needs to be addressed, and it needs to be addressed on the level that they can understand. Some folks don't want to do this because they think it encourages overcrowding, but it doesn't. What's done is done. How do you address it and get people to fill census? Make it known that private and personal information on the census is to remain PRIVATE AND PERSONAL FOR AT LEAST 72 YEARS. That means it doesn't matter how many is shacking up in a house or apartment, how much child support you are running away from, whether or not you not illegal, or a wanted criminal, a fugitive, a hide-away-refugee - anybody that is looking for you or trying to track you down CAN NOT use the census to get any information about you. That's what people really want to hear and if they can believe that, they will fill out the census and give an accurate count the number of representative that each state needs.
