The 2010 Census Avoid Followup Evaluation reports the results of the 2010 Census Alternative Individual Census Return questionnaire for group quarters and the 2010 Census Experimental Overcount questionnaire for housing units. These two experimental 2010 Census questionnaires were designed to collect enough information on the initial census return so that a determination could be made of an individual’s true residence status without the need for a follow-up telephone interview as part of the Coverage Followup operation. An independent sample was chosen for each experimental questionnaire. The total number of Alternative Individual Census Return questionnaires that were completed and data captured in three sample Local Census Office areas was 99,910. There were 20,663 data captured Experimental Overcount questionnaires containing 58,674 people in six sample strata.
