This publication uses the KIDS COUNT data from 2000 to 2005 to rank states based on improvements in child well-being in each state during that period. This is different than comparing the level of child well-being from state-to-state in that it shows whether a state is improving or deteriorating, rather than its status at a specific point in time. For each year from 2000 to 2005, a state composite index of child well-being was created, and the movement of this index over time indicates if general child well-being is improving or deteriorating. Collevtively, the data from each state characterizes progress on a national level. While most states (46 out of 50) improved during the 1990s, there are substantial differences among the states. California exhibited the biggest improvement during the 1990s (up 23%) followed closely by Maryland and New Jersey (up 21% each). Nebraska and Wisconsin experienced slight declines in overall well-being while Kansas and North Dakota showed no change over the decade.
