Um, Bobert, according to the stories I have read the number you mean is 300 million, or 300,000,000. For example, the Intenrational Heral Tribune says:
"PLANO, Texas America's population passed the 300 million threshold on Tuesday, marking a period where immigrants have arrived in numbers not seen for nearly a century and a time of explosive growth in suburbs such as this one north of Dallas.
Driving the expansion has been a steady birth rate, people living longer largely because of medical advances and, most influentially, a historic influx of foreigners that harks back to the country's melting pot roots.
At America's 100-million population mark, in 1915, about 14 percent of the residents were immigrants. At the 200-million mark in 1967, the number dropped to about 5 percent. Today, at nearly 300 million, it is back to 12 percent.
But as the U.S. population continues to surge -- researchers predict another 100 million people will arrive within 37 years -- handling residential growth and conservation of resources could become a more pressing national priority, particularly as increasing energy consumption intersects with tighter supplies of fuel and water."
