300 millionth American Predicted to be Hispanic
As the U.S. population is set to hit 300 million on Tuesday morning, demographers are betting the 300 millionth baby will be a Hispanic.

The milestone baby will be "a Hispanic boy born in Los Angeles County to a Mexican mother," predicts William Frey, a demographer at the Brookings Institution.

Although nobody will know for sure, demographers based their prediction on the fact that Latinos accounted for almost half the population increase in last year, more than any other ethnic or racial groups.

The Census Bureau projected that the U.S. population will hit 300 million at 7:46 a.m. Eastern Time Tuesday based on estimates of births, deaths and net immigration that add up to one new American every 11 seconds.

The estimated 11 million to 12 million illegal immigrants in the U.S. were included in official population estimates.

The population reached its last milestone of 200 million in 1967. Life magazine heralded Bobby Woo as the 200 millionth American. Woo was born in the Atlanta suburb of Tucker. His mother immigrated from southern China when she was 15 and his entire family is ethnically Asian.
