20th Century Canadaian Age cohorts
1) There are many possible explanations or theories which may justify the differences of cohort sizes of age groups in Canada in the 20th century. Many of the cohorts indicate that people’s decisions as to whether or not to have kids are influenced by the social, political and/or financial positions they face at different times. Before WWI, there were many people, especially in the early 1900s, who were just immigrating to Canada and settling into their new environments; it makes sense that they would not be ready to support new babies, which may explain the low proportion of births experienced per year at this time.
