Health limits kind or amount of work For the 1996-2004 panels, information on work-limiting disability comes from core question (edisabl) during wave 2 for people ages 15-69, when respondents were asked whether health limited the type or amount of work. This indicator is supplemented with details from the Functional Limitations and Disability topical module (wave 5 for 1996-2004 panels, variable ejobdif) that covers people ages 16-67. For the 1990-1993 panels, disability information comes from the core question (disab) during wave 2 for people ages 15-69, when respondents were asked whether health limited the type or amount of work. This information is supplemented with details from the Functional Limitations and Disability topical module (waves 3, 3, 6, 3 for 1990-1993 panels, variables TM8914, TM8918, and TM8920) that covers people ages 16-67. In order to make the sum_disab consistent for all panels, both responses were taken from the core and topical modules, when available, with any positive indication of health limiting the kind or amount of work flagging the positive response. .=Structurally missing, out of scope for question (sum_disab_in_scope=0)
