Source and number of deaths (from all causes) recorded by selected locations during the 1918 flu pandemic.

Recorded deaths (from all causes) by age in Montreal and Toronto, September and October, 1918.

Death rates (from all causes) by age in Montreal and Toronto during the month of October, 1918.
Figure 3.
Distribution of deaths (from all causes) by age as a percentage of all deaths between ages 15 and 44 in all available Canadian and American locations.
* *Key for Figure 3: Yearly age-specific death counts were available from age 18 to 31 for Philadelphia, Indiana, and Kansas in the special tables that were tabulated for these locations in 1920 (27); Outside this range, death counts were only available for collapsed age-groups (i.e., 15–17, 32–34, 35–39, and 40–44). For these age-groups we divided the number of deaths in the interval by its length and plotted the obtained number at the midpoint value of the interval. Other Canadian locations: Hamilton, Ottawa, London, Welland & Lincoln, Winnipeg, and Vancouver.
Figure 4.
Percentages of deaths by age from pandemic-related causes and from all other causes in Ontario and US locations, September to December 1918.
&&Key for Figure 4: Yearly age-specific deaths counts were available from age 0 to 4 and from 18 to 31 for the US locations in the special tables that were tabulated for these locations in 1920 (27); outside these ranges, death counts were only available for collapsed age-groups (i.e., 5–9, 10–14, 15–17, 32–34, 35–39, 40–44, ..., and 60–64). We divided the number of deaths in the interval by its length and plotted the obtained number at the midpoint value of the interval. Deaths above age 65 were not available by age or age-groups for the U.S. locations. Ontario locations: Toronto, Hamilton, Ottawa, London, and Welland & Lincoln; US locations: Philadelphia, Indiana, and Kansas.
