There was a news article that intrigued me as a genealogist for 50+ years who has used US Census records to collect information on my ancestors. It was a discussion of the possibility of NOT asking marriage information in future censuses possibly because of privacy concerns for the individuals involved; although the results aren't available to the public till 70 years after a census has been taken. Meaning that the1940 census was just released in 2010. Interesting for me because I hadn't been born yet the month the census was taken. My parents were living on the railroad in Nevada, but it gave me interesting information on them and who their neighbors were, etc. Each census varies on the info that is provided.
