a
Early responders completed a survey wave interview within the first 27 days of interviewing; late responders completed interviews on or after day 28. The responder status analysis was restricted to waves 2 through 5 from among 6 total survey waves.
b
Percentages do not always sum to 100% because of rounding.
c
Suppressed estimates are unstable with relative standard errors >30%, or no sample was observed.
d
We used hot-deck imputation procedures to assign the income group for 7.8% (198) of all respondents.
