This study analyzes trends in mortality by income in urban Canada from 1971 to 1996. It examines progress towards the goal of Health for All, lower mortality rates, inequality in mortality, and changes in specific causes of death. The findings reveal improvements in overall mortality rates but persistent income disparities in certain age groups. Eliminating these disparities would lead to significant gains in potential years of life.

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
