Conclusions: Trends 1971-1996

• Lower mortality for all income quintiles, both sexes, and for most causes

• Persistence of an income gradient, though less steep than formerly• affects females as well as males, though less sharply

• highest relative risks in working ages (25-64)

• Elimination of the remaining disparities would result in gains in potential years of life equivalent to

eradicating one of the three leading causes of death

Conclusions: Trends 1971-1996 (cont.)

• Throughout this period, there were substantially diminished differences across the income quintiles, overall and for most causes of death

• many causes showed remarkable progress: reduced mortality and diminished differences

• a few causes showed higher mortality and greater inequality

• timing of the changes varied by cause
