Now we know children need fathers to thrive. But two decades ago, fathers were slipping off the radar and out of kids’ lives. In the face of the foregoing, the Casey Foundation set out to provide leadership in an effort to change the policy environment and improve child outcomes through better fathering. The Foundation sought to help promote large-scale programs and policy commitments that could change the attitudes and behaviors of young men. Those efforts, theories, challenges and social-shift accomplishments are presented in this report.
