The Arizona Youth Tobacco Survey is a series of biannual school-based tobacco-focused surveys first implemented in the spring of 2000. The survey is designed to help monitor trends in tobacco use among public school students in grades 6 through 12 and to compare changes in rates over time. The survey also collects data on topics including: tobacco use; tobacco-related knowledge, attitudes and beliefs; access to tobacco products; exposure to environmental tobacco smoke; initiation and cessation; influence of family, friends and the media; and social, school and community interventions.

The 2009 Navajo Nation Long Range Transportation Plan is a twenty-year comprehensive plan developed and updated by the Navajo Division of Transportation in a five-year cycle. The plan identifies the Nation’s multi-modal transportation needs over the next 20 years and develops strategies to meet them. The plan provides long range planning policies and implementation strategies for the Navajo Indian Reservation Roads Program improvements. It is based on a comprehensive analysis of all pertinent factors and issues affecting the Navajo Nation’s existing and future transportation needs.
