Regarding the type of information that is requested and the history of the census, which you laid out very nicely, I thank you and appreciate it.
That being said, I will still answer question #1 - how many reside at this household as of April 1, and #9 - race = American. And since I can't stand the commie pig 0b0z0 chief usurper-in-crap, or the socialist demoRAT pigs in office & their orwellian bureaucracies, I am looking forward to opening up a can of whoop ass on the poor census worker, beginning with a rant against 0b0z0 and his missing long form birth certificate, his inability to get a U.S. passport until 2004 when he became a U.S. senator, his missing academic records, his multiple social security numbers, etc. Does the census worker have anything to do with 0b0z0's missing information? Of course not. I'm just looking forward to a good old fashioned ranting and ass whooping on the fed "gubmint"!
Actually, 72 years is when families forget who great grandma was, etc. Also key to getting back to 82 years, 102 years, etc. In my own case, my dad’s family was well known, those people never tired of talking about themselves. My mother’s side was just the opposite, no one knew very much about those not living.
I think your time and energy would be better put getting rid of your elective representative, whomever that may be. I understand the frustration with government, though - its gone too far no doubt.
