What are the Federal Poverty levels for 2008?

It really depends on the number of people in the household. Per the table link, for an average family of 4 the poverty threshold is $22,000.

Poverty thresholds are used for calculating all official poverty population statistics - for instance, figures on the number of Americans in poverty each year. They are updated each year by the Census Bureau. The poverty guidelines are a simplified version of the federal poverty thresholds used for administrative purposes - for instance, determining financial eligibility for certain federal programs. They are issued each year in the Federal Register by the Department of Health and Human Services (HHS).
