Quotes About Response rates

We administered our main surveys by mail for methodological reasons. More than other types of survey research, mail surveys provide respondents with a feeling of anonymity and encourage them to be more open to sensitive questions. Also, in mail surveys, respondents have more time to recall the past and this improves their ability to remember. In addition to this, the response rates in mail surveys are at least as good as in face-to-face or telephone surveys

our surveys received response rates of between 45 and 50 percent, which are generally considered very admirable in survey research dealing with older populations in large cities.
