* Difference in life expectancy between periods 20012004 and 19891992 (an absolute measure of change over time). Differences may not add up because of rounding. † Absolute difference in life expectancy between the bottom and top deciles, obtained from regression of mean life expectancy on mean relative rank of deciles. ‡ Proportionate increase in life expectancy between the highest and lowest deciles. §Absolute difference in life expectancy between the bottom and top deciles, adjusted for ruralurban classification and presence of Aboriginal areas (refers to the coefficient obtained from linear regression of life expectancy of CLSCs  not of deciles  on the mean relative rank of deciles).
