Note: The sample error decreases beginning in 1990 due to the purchase of working telephone

numbers from a private sampling firm, which guaranteed more of a first-stage sampling procedure

than was the case with the previously used two-stage sampling process.

Note: The sample error increases beginning in 2008 due to the decline in the response rate,

reflecting a national phenomenon (Bardes and Oldendick book, 2012, page 283).
