New Jersey children and families begin this new decade with the state and nation in an economic downturn that has been marked by widespread job losses, an increased rate of child poverty and a growing number of households without enough to eat. These challenges are reflected in the measurements of child well-being in this report. "New Jersey Kids Count 2010" also shows that in the midst of this tough economy the state has achieved important successes for children and families. New Jersey has a nationally acclaimed preschool program that changes lives. More than 40,000 young children are enrolled in this high-quality, full-day program that increases their chances of success in school and in life. New Jersey is also ahead of many states in efforts to provide health coverage to uninsured children. The state has reduced the number of children without health insurance by 11 percent since 2004. It has also doubled the number of needy families receiving state assistance to pay home heating bills. These achievements make a real and important difference--for children, for families and for the future of the state. These successes provide a foundation on which to build.
