For today’s geo quiz we asked whether the number of immigrants to the US is going up or down, and where most of them come from. Anchor Lisa Mullins gets the answer from William Frey, a demographer at the Brookings Institution in Washington. He says at least half of the people coming to the United States are from Latin America…and that newly released census numbers for 2007 indicate a slowdown in immigration.
Today we’re looking for a central Mexican state that borders the state of San Luis Potosí … and the state of Mexico. The answer is the state of Queretaro. The World’s Jason Margolis takes us there to explore the Sotano Del Barro. It’s a deep underground well created millions of years ago by shifting tectonic plates.
