This Kids Count supplementary report provides county-by-county information for 1997 and 1998 on key indicators of child well-being: (1) infant mortality; (2) low birth weight; (3) births to 16- and 17-year-olds; (4) teen unmarried births; (5) child abuse and neglect; (6) high school graduation; and (7) child poverty. The supplement updates the 17-year trend data provided in "County, State and Nation: Trends in the Well-Being of Iowa Children, 1980-1996." In addition, the supplement discusses statewide trends in child well-being contrasted with general Iowa economic trends and national health goals established for the 21st century in "Healthy People 2000." The supplement concludes by noting that despite economic recovery in the state during this period, indicators of child well-being have not markedly improved and have in many cases worsened. Finally, the supplement provides a listing of special reports and features produced by Kids Count since 1991. (EV)
