Now I´m back after reading the question... just googled LOL
I think here we´ll have a culture shock, so please be patience with my opinion.... US is known to be worried with freedom, so I think I understand what I was calling "paranoia".
After reading my first thought was "SO WHAT?" I was imagining really weird question, asking about your incoming or whatever... but they only wanna know how much you are and what color u.u How can this be so "not free"? I really don´t understand the worry.
The government need this information, IMO, to know if the population has their own houses, or if they live paying rent... if the US has big families, small families, single men/women living alone etc.
Really don´t see any problem.
Here they ask how many bathrooms are in the house, how your garbage is disposed, if you´ve gone to college, if you know how to read and write, the income of the house owner etc...
