Table 6 shows that the overall high welfare use rate for immigrant households with children is not simply due to legal status. Both legal and illegal immigrants tend to make use of the welfare system. Illegal immigrant households with children primarily use food assistance and Medicaid, making almost no use of cash and housing programs. In contrast, legal immigrant households with children tend to have relatively high use for every type of program. In addition to legal status, Table 6 also reports welfare use for different types of legal and illegal households. The Department of Homeland Security estimates that more than half of all illegal immigrants come from Mexico.22 The table shows that households with children headed by Mexican illegal immigrants tend to have somewhat higher welfare use rates than do illegal immigrant households with children from all countries. As for legal immigrants, Table 6 shows that the inclusion of refugee-sending countries in the data does not make much difference to overall welfare use rates for legal immigrant households with children. Use rates for households headed by legal immigrants from non-refugee-sending countries are very similar to those for legal immigrant households when refugees are included. Refugee-sending countries are a small share of the total and, as we have seen, their use rates are not different enough from non-refugees to impact the overall results in a meaningful way.
