Document Summary

Ch&e 4010 lecture 4 january 20, 2021 measuring mortality: direct and indirect standardization. Population pyramids: describe the age structure of a population for a given time period, graph differences in proportion of population in each age group, males/females reported separately, effect of both mortality rates and fertility rates. The pyramid at 1950 has a wider bottom, meaning that the population is younger. The pyramid at 2017 has a wider center, meaning that the baby boomer generation is getting older. Comparing populations globally: without accounting for differences in age structure, crude or unadjusted comparisons of mortality rates in. Canada between 1950 and 2017, or between developed and developing countries would be inappropriate (and not particularly informative! The table is broken down by crude age groups. The first comparison is looking at crude rate, which is just the number of death within a population without age adjustment. We might be tempted to compare the 0-39 group to 40 years + group.
