NOTE: The unemployment rate is defined as the percent of the field-specific labor force who are not employed and are seeking work. The field-specific labor forces include individuals who have Ph.D.s in these fields and who are either employed or unemployed. Estimates are subject to sampling error. 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.
