"It gives an interesting statement of purpose on the home page, and lots of census information. What one of my researchers here in Lake Zurich is doing is printing out the questions that were asked of people for the 1940, 1950, 1960, 1970, 1980, 1990, 2000 censuses and using those questions when she is interviewing family members. 'What do you think you answered when you were filling out this census?' The web site also provides all of the same information from 1850-1930, the printable census forms for 1850-1930 will provide the questions/columns necessary. I always keep a printout handy when I’m teaching someone.” - Carol Bartlett
