>>Based on Census Bureau data, the study estimates that households headed by illegal aliens used $10 billion more in government services than they paid in taxes in 2002. These figures are only for the federal government; costs at the state and local level are also likely to be significant. The study also finds that if illegals were given amnesty, the fiscal deficit at the federal level would grow to nearly $29 billion.<<
Census Bureau data is like everything else from the government, the data is behind times. I am presuming that this is the year 2000 data figures.
Looks like 2002 figures to me.
