Census is very important for every country, it can tell the changes of the population and help the government to carry out some policies. In America, the government counts the population every ten years and the latest census was in 2010. The results of the census show some changes in this country. First, the growth of the population is very slow. It is obvious that the more rich, the less children people want to have, because they want to focus their energy on the career and when they have time, they would rather enjoy the personal hour. Second, the number of immigrants is increasing, which will become the majority of American population. What’s more, the immigrants give birth to children more than the local people do, so it has been predicted that in the future, the gene of blond hair and blue eyes will disappear. 
人口普查对每个国家都非常重要,它可以显示人口的变化，帮助政府实施一些政策。在美国,政府每十年就统计人口，最新的人口普查是在2010年。人口普查的结果显示在这个国家的一些变化。首先,人口的增长速度非常慢。很明显,越有钱的人,想要孩子的越少,因为他们想要把精力放在事业上,当他们有时间了,他们宁愿享受个人时间。第二,移民的数量越来越多,这将成为美国人口的大多数。更重要的是,移民生的孩子比当地人更多,所以根据预言,在未来,金发和蓝眼睛的基因将会消失。
