survive to old age, their mortality rates converge toward those for older whites, although blacks remain disadvantaged (Elo and Preston 1994).The racial gap in mortality during the prime adult ages points to the need to understand chronic health problems of middleaged blacks and whites. Middle age, defined here as ages 51 to 63, designates the lifecycle period when the racial gap in health is potentially at its greatest (House et al. 1994). Our overall goal is to identify racial differences in "life without health problems" to better specify the pathways that lead to racial differences in mortality and to differences in the quality of life lived. We define health problems broadly to include the major fatal and nonfatal chronic diseases, conditions, and impairments, functional difficulty, and disability.Two basic questions guide our analysis. First, are blacks consistently disadvantaged relative to whites across all major chronic eath truncates the lives of black Americans at younger ages than whites, with greater racial differences observed for men than women. National life table estimates for 1996 predict a life expectancy at birth for black men of 66 years compared with almost 74 years for white men (Ventura et al. 1997). Much of this difference is due to the racial disparity in mortality rates prior to age 65. Should blacks D
