California has the highest number of illegal immigrants residing in its borders. The estimated number of illegal alien residents in California was about 2.2 million, or nearly 32 percent of the total number of illegal immigrants in the United States.

An estimated 7 million illegal immigrants were residing in the United States in January 2000. This is double the size of the illegal immigrant population in January 1990 and constitutes 2.5 percent of the total U.S. population of just over 281 million.

Births to illegal immigrants now account for nearly one out of every ten births in the United States.

The Center for Immigration Studies found that illegal immigrants cost the United States taxpayer about $10.4 billion a year. A large part of that expense stems from the babies born each year to illegal immigrants.

In the United States, oil demand is projected to grow by 340,000 barrels per day this year and gasoline demand is projected to grow nearly two percent, averaging 9.3 million barrels per day for the summer.
