The purpose of this brief report is to paint a high-level picture of children in Canada, and their health and wellbeing, using readily available, reputable sources of data. We begin by describing the current population of children across Canada and trends over time. Do we have more or fewer children in Canada now compared to the past? What about the future? Which parts of the country do they live in? The report then turns to the health and wellbeing of our children. What do we know about the health status of children in Canada, both mental and physical? What about key social determinants of health, given their importance to health and wellbeing? How does Canada compare to other countries with similar standards of living?
