This resolution does not legally require anyone to do anything, so it doesn't directly affect any specific group of Americans in a mandatory way. However, it aims to inspire and influence the behavior of all Americans by encouraging them to participate in more play, social interaction, and physical activity.

Children, families, and communities might be indirectly affected if local organizations, schools, or community centers choose to organize events inspired by the "National Day of Play." This could lead to increased participation in healthy, social activities across the country.
