Improving upon probability weighting for household size
نویسنده
چکیده
By comparing data from national telephone polls to Census gures on household size (number of adults in household), we nd large diierences between population and sample, even after weighting respondents proportional to household size. This presumably occurs because larger households are easier to reach and more likely to respond to the survey. If a user wishes to weight on household size, we recommend poststratiication on known population proportions of household size instead.
