NOTE: See Appendix Table F-8. Comparisons between 1991 estimates and those of earlier years should be made with caution due to changes in survey methodology. Prior to 1991, the SDR collected data by mail methods only. In 1991, the survey had both a mail component and a telephone follow-up component. In this table, 1991 estimates are based on "mail-only" data to maintain greater comparability with earlier years.
