The factbook next summarizes findings from the Wyoming Youth Risk Behavior Survey 2001. The remainder of the factbook presents county profiles addressing selected demographic, education, child health, and well-being indicators for the period 1990-2000. The data indicate declining trends in low birth weight babies, child and youth population, births, and juvenile arrests for all crime types. Increasing trends are noted for the percent of babies born to single mothers, percent of children living in poverty, and births of mothers with only a high school education or less. The factbook concludes with information on advocacy opportunities. (HTH)
