U.S. census records are kept private for 72 years to protect respondents' privacy, then released to the general public. However, most genealogists are not aware that it is possible to obtain information from newer census records.
The fact is that records from the 1950 to 2010 Censuses are available but can only be obtained by the person named in the record or their heir after submitting form BC-600 or BC-600sp (in Spanish).
NOTE: Publications related to the census data collected from 1790 to 2010 are available at https://www.census.gov/prod/www/decennial.html. However, none of those records list names and other personal information given by the respondents.
