In question 18 on the 1990 census forms, we asked people if they had a work disability—a condition that had lasted 6 months or longer and which limited the kind or amount of work they could do at a job—and if that disability prevented them from working at a job.
In question 19, we asked people to tell us if they had a mobility limitation—a condition that had lasted 6 or more months and which made it difficult to go outside the home alone—or a self-care limitation—a condition that made it difficult to take care of their own personal needs, such as dressing, bathing, or getting around inside the home.
