How does SLAITS adjust the data to account for noncoverage of households without telephone service?
Survey weighting and estimation procedures are customized for each survey sponsor, and are detailed in the survey-specific methods reports. In general, SLAITS uses information collected on interruptions in telephone service to adjust for bias that may result from noncoverage of households without telephone service. Background information for these procedures is available from the following references:
