DEFINITION: Child poverty index is defined as the share of the children living in the households with income below 50% of the national median.

Because your USA household has low income does not mean you are the same situation as say a Mexican child who is in the same statistical group. "Never mind then" is a good response until the/a report shows a apple to apples type of conclusion with the appropriate figures included. Right now you could measure children living in Manhattan on 5th ave against a kid in Louisiana and the report may say the kid living in a bayou shack was not in poverty and the kid in Manhattan apt was.
