The aim of this paper is to explore mortality in Quebec during the nin
eteenth century from a demographic perspective. During the nineteenth
century, there was excess urban mortality in various countries; in ord
er to identify such mortality differentials, we compared mortality ind
icators for the province of Quebec and then for the urban areas of Mon
treal and Quebec City. Using data from various studies, we produced li
fe tables and compared life expectancies. We show that at different ti
mes during the nineteenth century, spatial variations in mortality lev
els across the province of Quebec and its urban areas were significant
. According to the data we analyzed, mortality is undoubtedly higher i
n urban areas even though a convergence in trends took place towards t
he end of the century, resulting in an overall reduction in mortality.
Also, exploring life expectancies within a cohort approach at times o
f fast-changing mortality patterns has proved to be instructive. Life
expectancy estimates based on a cross-sectional approach were systemat
ically lower than those resulting from a cohort-specific one. Trends d
iverged to a greater extent beginning with the 1870 cohort, reflecting
the improvements made from that point on to World War II. Since curre
nt mortality levels are substantially determined by the cumulative eff
ects of past behaviour specific to each generation, it is quite obviou
s that mortality analysis will reveal its true meaning only with the h
elp of cohort life tables.
