Globalization has contributed to rising incomes in Canada, the United States, and Mexico but has not improved economic security for many vulnerable children across the three countries, according to this report.

The study completes a series published by Casey as a partner in the Children in North America Project, a project that highlights the well-being of children and youth in all three countries. Previous reports have explored health and safety issues and the challenges facing children in an era of globalization.
