Abbreviations: SE, standard error; GAD, generalized anxiety disorder; PTSD, post-traumatic stress disorder; PD, panic disorder. All estimates are weighted to be nationally representative of the given population and subpopulations in the coterminous 48 states of the U.S.

^aPercentages represent the probability of an individual from a given race/ethnic group developing the focal disorder by the ages indicated in the column headings. Estimates were derived from Kaplan-Meier curves containing respondents who developed the focal disorder by their age at interview as well as those who did not.

^bAge of onset percentiles represent the ages by which 25%, 50%, and 75% of respondents developed the focal disorder. Estimates were derived from Kaplan-Meier curves containing only those respondents who developed the focal disorder by their age at interview.
