... Call-History File: A call-history file is the file that houses disposition codes (labels) for each call made, on each call attempt, during the recruitment phase of the survey process.

... . Cluster Sampling: In cluster sampling the total population is divided into clusters of sampling units, usually on a geographic basis, and clusters sampled randomly with the units within the selected clusters either being selected in total or else selected randomly, usually at a very high rate (Richardson et al., 1995, p.

... . Disproportionate Sampling or Stratified Sampling with Variable Sampling Fraction: A sampling method in which the population is divided into strata, and different sampling rates are used for each stratum.

... Locating Letter: A letter sent by mail to the respondents in advance of the next data collection period in an effort to obtain updated addresses and telephone numbers before the next round of data collection (Zimowski et al., 1997b)

... . Post-Stratification: The process of weighting stratified data to compensate for different sampling rates in the strata.

... . Recall attempts include contact attempts by telephone, personal visit, mail, or possibly email.

... . Rotation Group: A sample of units drawn from the population at the same time and following the same schedule of data collection in a rotating panel design (Zimowski et al., 1997b)

... Weighted Response: A response rate that is calculated using the inverse of the selection probabilities as the weights. If different selection probabilities exist within different strata or different stages of complex sampling designs, the weighted response rate is a weighted aggregation of the response rates in the strata and stages (adapted from Zimowski et al., 1997b)
