This Kids Count data book for 2000 examines statewide and county level trends in the well-being of Michigan's children. The statistical portrait is based on indicators of well-being in the areas of: (1) economic security; (2) child health; (3) child safety; (4) adolescence; and (5) education. Part 1 of the data book reviews Michigan's progress on a selected group of child well-being indicators included in the national Healthy People 2000, noting that the state is not close to achieving most of them. Most achievements have been made among the adolescent measures, particularly in reducing violence and pregnancies. Trends in maternal and child health have either been flat throughout the decade or show stalled improvement. Measures for children showed mixed results. Part 2 of the data book features an in-depth discussion of childhood asthma, its effects on children, risk factors for the disease, the scope of the problem in Michigan, initiatives to control and combat asthma, and recommendations for further action. Part 3 summarizes findings of children's well-being compared to other states and summarizes trends represented in the state profile. This part notes that in the past decade, Michigan has shown the most extensive improvements in education and in mortality rates. However, access to health care and economic security worsened between 1988 and 1998. Part 4, comprising the bulk of the data book, presents profiles of child well-being statewide and for each county. The report concludes with data notes and sources. (KB)
