As the debate on illegal immigration rages in Washington and state capitals, it’s troubling to see both sides rely on emotional rhetoric to the detriment of facts. The impact of illegal immigration on public education is a case in point.

No one can deny that increasing numbers of children of illegal immigrants attend public schools in the United States and that U.S. taxpayers pay the costs. Those sympathetic to illegal immigration tend to remain silent about these costs, while illegal-immigration opponents often fall short on specifics.

Nearly half, 47 percent, of illegal-immigrant households consist of parents with children. This proportion is more than double that of U.S.-born households, where just 21 percent are parents with children. Over the years, the number of children of illegal immigrants has increased significantly.

In 2003, there were 4.3 million children of illegal immigrants. By 2008 that number had climbed to 5.5 million, more than the entire population of Colorado. The large number of children of illegal immigrants greatly impacts public schools and education-funding costs.
