This Kids Count report presents statewide trends between 1988 and 1996 in the well-being of Massachusetts' children. The statistical portrait indicator areas and topics examined include: demographics (children as percent of population, children by race/ethnicity, students whose first language is not English); economic well-being (percent of children living in poverty, children dependent on assistance programs, medicaid; EPSDT--Early and Periodic Screening, Diagnosis and Treatment); teen families (teen birth rates: Massachusetts vs. USA, Massachusetts births: teen vs. all women); and health (trends in adequacy of prenatal care, low birthweight: age and race/ethnicity, low birthweight: level of prenatal care and race/ethnicity, infant mortality by race, uninsured Massachusetts children). Findings indicate that between 1988 and 1996, Massachusetts dropped from 5th to 13th place nationwide on a range of indicators of child health and economic well-being. Massachusetts ranked 44th nationwide in its rate of improvement on key indicators. There has been considerable improvement in teen birth rate, and Massachusetts' infant mortality rate is the lowest in state history, although there is still a gap between black and white infant mortality rates. There have been increases in the number of children without health insurance and those living in poverty. (Contains about 20 references.) (KB)
