From the Population Research Bureau, this outlines recent data on the cost of child poverty by State. Specifically, children that grow up in poverty have negative health, social, and economic consequences, which can have large costs for States. California, with an estimated 1.7 million poor children in 2006, had the highest cost of child poverty at $63.9 billion, followed by Texas at $57.5 billion and New York at $33.4 billion.
