The 2008 Sleep in America poll was conducted for the National Sleep Foundation by WB&A Market Research. Telephone interviews were conducted between September 25 and November 19, 2007, with a targeted random sample of 1,000 Americans. A random sample of telephone numbers was purchased from SDR Consulting, Inc. and quotas were established by region. The response rate for this study was 17% (number of completed interviews divided by the number of completed interviews plus the number of contacted households who refused participation or did not complete appointments, factored by the overall incidence of 71%). The data was weighted to reflect equal proportions of respondents by age based on the U.S. Census. The maximum sampling error of the data for the total sample of 1,000 interviews is plus or minus 3.1 percentage points at the 95% confidence level. The sampling error will vary depending on the sample size and the percentages being examined in the sample.
