According to demographers, more white Americans died last year than were born -- the first time this has occurred in the history of the nation. Even more surprising, the shrinking of the white population has begun more rapidly than previously predicted. The decline of America's white population is being fueled by a variety of factors, among them that white women are having fewer children, and at later ages than other racial groups, and the immigrant population is increasing. 

A new report by the Centers of Disease Control and Prevention shows that the teen birth rate for African Americans has declined by 60 percent between 1991 and 2011 – a rate 10 percent greater than the overall dip in teen birth rates. Over the past decade, the national teen birth rate has declined from 31 out of every 1,000 girls between 15-19 giving birth in 2011, compared to 61 girls per 1,000 in 1991. In 2007, the Hispanic teen birth rate was 21 percent higher than the Black teen birth rate; in 2011 it was only four percent higher.
