The annual income a New Jersey family of four would have to earn in order to have the same purchasing power as three times the federal poverty level in 2008 was $81,432, according to the Kaiser Family Foundation’s statehealthfacts.org. Nationally, three times the federal poverty level for a family of four was $63,600. (This year, the federal poverty level for a family of that size is $22,050.) Nevertheless, purchasing power goes a lot further in other parts of the country, so you would have to have a higher income in the Garden State to be considered well above the national poverty line. About 55 percent of New Jersey families met that goal, according to the website.
