   This week, the national population clock at the United States Census Bureau reached 300 million. This is only an estimate -- the next official count is in 2010. But the Census Bureau says the United States is gaining one new person every eleven seconds. Government experts based this on an estimate of one birth every seven seconds and one death every thirteen 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 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 fifty-five percent of new population growth has resulted from immigration, including the children of immigrants. Today twelve 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 50 years later, in 1967.

       本周, 放置在美国人口普查局的人口记数钟显示美国人口总数已达3亿. 这只是估计的数字, 下次的官方人口统计是在2010年. 但人口普查局表示美国平均每11秒钟新增1人。政府专家是根据每7秒钟有一名新生儿诞生,每13秒钟有1人死亡的基础上来计算的. 他们也考虑到移民. 人口普查局称每31秒钟就有1名新移民进入美国. 美国已是世界第三人口大国. 虽然人口数目远小于中国和印度. 一些医院声称第3亿名是在他们那里出生的. 但第3亿名也可能是已进入美国的新移民. 专家表示约55%的新增人口来自移民, 包括移民的子女. 现今12%的人是外国出生. 且主要都来自墨西哥. 但过去, 通常来自欧州.
1915年美国人口总数为1亿，仅仅50年后即1967年就达到了2亿。
