Response Rates and Reasons for Noninterviews (in percent) — Group Quarters
Note: As a result of the 2013 government shutdown, the ACS did not have a second mailing, a telephone followup, or a person followup operation for the October 2013 housing unit panel. Only respondents from the first mailing (Internet in the United States, paper questionnaire in Puerto Rico) contribute to the overall response for this panel. This caused a drop in the annual housing unit response rate of about 7 percentage points. If we exclude the October panel from the calculation, the annual housing unit response rate rises to 97.1%. Similarly, due to a reduction in funding in 2004, the telephone and personal visit followup operations for the January 2004 panel were dropped, which resulted in a comparable effect on the overall 2004 response rate.
