大学考试|US population estimated to reach 400 million by 2043

This is IN THE NEWS in VOA Special English.

This week, the national population clock at the United States Census^{1 Bureau reached 300 million. This is only an estimate -- the next official count is 2010.}

But the Census Bureau says the United States is gaining one new person every 11 seconds. Government experts based this on an estimate of one birth every seven seconds and one death every 15 seconds.

They also considered immigration. The Census Bureau says an immigrant enters the country every 31 seconds.

The United States is the third most populous^{2 country in the world, although it is still much smaller than China and India.}

Some hospitals claimed they had the 300 millionth baby. Yet the 300 millionth person in the United States could have been an immigrant. Experts say about 55 percent of new population growth has resulted from immigration, including the children of immigrants.

Today 12 percent of the population is foreign-born. The leading place of origin is Mexico. In the past, it was Europe.

America's population reached 100 million in 1915. It reached 200 million just over fifty years later, in 1967.

But the country has taken less than 40 years to reach 300 million people. And researchers expect a population of 400 million in even less time.

At that point, in 2043, non-Hispanic whites could make up just over half the population.

In 1967, more than 80 percent of Americans were white. Less than five percent were ofSpanish ancestry^{3. Today, Hispanics -- either American-born or foreign-born -- make up almost 15 percent of the population.}

about 13 percent of the population is black, and about five percent is of Asian ancestry.

The population growth in the United States is unusual among big industrial nations. Japan and some European countries expect their populations to decrease over the next 20 to 30 years.

America is known as a nation of immigrants. But today, as at other times in its history, immigration is also ahot issue. There is debate especially about the millions who are in the country illegally.

Reporters were invited to watch the Census Bureau clock hit 300 million Tuesday morning. There was no big ceremony, although bureau employees later held a small event of their own at their offices near Washington.

President Bush released a statement. He said the new population mark is, in his words, further proof that the American Dream remains^{4 as bright and hopeful as ever.}

In 1915, the most popular names for babies in the United States were John and Mary. This year they are Jacob and Emily.
