1 Rates are calculated as follows: completed interviews [(completed
interviews + partial interviews) + (refusals + non-contacts + other) + e],
where e is an estimate of the proportion of unknown outcomes that are
eligible. e was calculated based on the number of returns or phone calls
that indicated a sample member was deceased (0.5% of the total sample).
