Purpose: To examine demographic characteristics and work conditions of home care aides, nursing home aides, and hospital aides in the late 1980s and late 1990s. Design and Methods: This study replicated a previous study which examined the Current Population Survey (CPS) March supplement from 1987 to 1989. The present study examined CPS data from 1997 to 1999 both to obtain a profile of aides in the late 1990s and to compare 1990's work conditions and demographic characteristics with those of aides in the late 1980s. Results: Whereas demographic characteristics and work conditions of hospital and nursing home aides show little change over the decade, home care aides today are generally younger, more educated, more likely to hold full-time positions, and more likely to have health benefits than their counterparts 10 years ago. Yet work conditions are still poorer for home care aides than for the other types of aides. Implications: Work conditions need further improvement, particularly for home care aides. More accurate data to describe paraprofessional care workers are also necessary to address the serious worker shortage problems.
