A child advocacy group's annual survey of the overall wellbeing of New Jersey's kids reveals there is a wide gap between the county where they fare the best, and the one where they fare the worst.

The results of the Advocates for Children of New Jersey's Kids Count 2012 show that child wellbeing is often, though not always, tied to wealth.

NJ Spotlight’s latest interactive map, shows that in Union County, 17% of children live in poverty according to 2010 data. The number compares somewhat favorably with Essex County to the north where 23 percent of children live in poverty. However, it's well above other parts of the state such as Morris County and Hunterdon County where 6% and 5% of children live in poverty, respectively.

In Union County, fifteen percent of children qualify for food stamps, while 11 percent receive free/low cost breakfast. Thirty-eight percent of all children in Union County receive healthcare through NJ Family Care or Medicaid.
