Story summary

Peter Jon Mitchell, writing in the National Post, discusses declining rates of marriage among young adults aged 25 to 54 in Canada, which has led to a decrease in children being raised by married parents. The trend is measured through census data from 2001 to 2021 and includes total fertility rate statistics. Mitchell notes that the sharpest decline occurred between 2016 and 2021, possibly due to pandemic effects. He argues that marriage generally correlates with better health outcomes, economic benefits, and increased social mobility for parents, while children from married families tend to have higher educational achievements and positive mental health. This shift could make having children less common within traditional marital contexts, impacting societal norms around family formation in Canada.
