美国人口普查 Census in America_英语作文
美国人口普查Census in AmericaCensus 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。

美国人口普查资料
2002年美国人口普查局发布的几份报告2002年美国人口普查局发布的几份报告美国人口普查局报告发表：《美国参考》2002年2-6月；学术交流网/网友学术交流/200 2年7月15日发布；学术交流网/美国统计资料/2002年8月19日重发（一）美国人口普查局从全球角度分析美国人口据美国人口普查局2月6日发布的报告，美国人口为2.81亿，仍是仅次于中国和印度的世界人口第三大国。
2002年2月6日人口普查局参照全球状况分析美国情况并确定老龄化和人口出生率的发展趋势根据商务部人口普查局今天发表的一份分析报告，90年代美国人口增加13%，使其继续保持世界人口第三大国的地位。
根据一份题为《从全球范围看美国人口》的2000年人口普查简报，2000年的美国人口超过除中国(13亿)和印度(10亿)以外的世界任何国家。
世界人口总数为61亿。
人口普查局国际项目中心的负责人彼德·韦说：“一个国家的人口总数只能反映其人口状况的一小方面。
一个国家的人口增长率和年龄-性别结构能说明这个国家所面临的挑战，体现在为儿童和老年人提供医疗保健，让青少年受教育，为年轻人提供工作机会和老年福利等方面。
”美国15岁以下的人口占世界15岁以下总人口的3%，在所有国家中居第四位。
美国的老年人口占世界老年人口总数的8%，在所有国家中居第三位。
这份简报指出了美国和其它发达国家年龄结构的变化。
例如，很多发达国家五岁以下的儿童人数在90年代后期都有所下降。
这份报告说，人口出生率低的国家将在未来的几十年中面临老年人口增加，新劳工人数减少。
美国人口目前占世界人口总数的不到5%，但是美国90年代的增长率是所有其它工业化国家增长率总和的五倍：13%对2.5%。
90年代人口大幅度增长的其它世界大国有：印度，增长率为19%；中国，增长率为11%；尼日利亚，增长率为33%；以及印度尼西亚，增长率为19%。
这些国家和美国增加的人口占90年代全球人口增长总数的将近一半。
解读美2010人口普查
解读美2010人口普查环球时报特约记者李雪报道美国《时代》杂志12月21日发表题为《美国2010年人口普查结果透露何种信息》的文章，从对经济、政治等领域可能产生的影响，对美国2010年人口普查结果进行了深入分析。
总人口首破3亿大关三大原因致增速放缓12月21日，美国人口普查局公布的统计结果显示，截至2010年4月1日，美国总人口达到3亿874万5538人，较2000年的2亿8142万1906人增长9.7%。
这意味着美国总人口有史以来首次突破3亿。
不过，过去十年也是1940年以来美国人口增速最低的十年。
上世纪30年代，经济“大萧条”导致美国人口增速放缓。
分析认为，2000年以来美国人口增速下降主要有三大原因：一是两次经济衰退；二是对于移民的警觉性日益增强；三是海外对于美国的观感日渐恶化。
然而，美国新罕布什尔州立大学人口学教授肯尼思•约翰逊指出：“美国人口增长速度依然很快。
但是这一统计结果显示，过去十年的最后一段时间里，移民进入美国的速度显著放缓。
”与上个千年最后十年的人口增长速度相比，过去十年的人口成长速度显著放缓。
当时(1990年至2000年)，美国总人口大增13%。
有分析表示，美国人口成长主要来自于国内新生儿。
据约翰逊教授估计，过去十年新增的约2700万美国人中，1700万为美国国内新生儿，另外1000万新增常住人口则由移民构成。
美国人口普查局局长罗伯特•葛罗夫斯也表示，很难确切地说，是否是经济严重衰退和移民管制更加严格造成美国人口成长趋缓。
他也指出，约60%的人口增长是新生儿，移民仅占40%。
人口日渐西南移加州独占鳌头此次普查的对象是美国50个州和哥伦比亚特区的常住人口。
普查结果显示，从地区看，美国人口日渐向南部和西部转移。
数据显示，过去十年，美国南部和西部人口大量增加，分别增加约1432万人和875万人。
东北部和中西部地区人口也有所增加，但增长速度较慢，分别增加约172万人和253万人。
有分析认为，如果不是经济严重衰退毁损诸如拉斯维加斯和菲尼克斯在内的西部大都市的住房市场，西部和南部的人口增长幅度可能更大。

美国贫困线标准2024
美国贫困线标准2024美国贫困线标准2024根据美国国家政府的定义，贫困线是指一个家庭根据其家庭人数和收入水平来确定是否属于贫困人口的标准。
贫困线的制定是为了帮助政府和社会组织了解和解决贫困问题。
1. 根据美国人口普查局（Census Bureau）的定义，2024年贫困线标准的依据是2024年的生活费用指数（Consumer Price Index，CPI）。
根据CPI的测算结果，美国贫困线的定义与家庭人口数量和州际差异相关。
2.单人家庭的贫困线：对于一个成年人而言，其年收入低于12,880美元即被定义为贫困。
这一数字基于饮食、住房、交通、医疗保健、衣物和其他日常开销的消费水平。
3.双人家庭的贫困线：对于一个居住在美国的双人家庭而言，其年收入低于17,420美元即被定义为贫困。
4.三人家庭的贫困线：对于一个居住在美国的三人家庭而言，其年收入低于21,960美元即被定义为贫困。
5.四人家庭的贫困线：对于一个居住在美国的四人家庭而言，其年收入低于26,500美元即被定义为贫困。
6.更大家庭的贫困线：对于超过四个人的家庭，每增加一个人，贫困线将相应增加4,540美元。
需要指出的是，这些贫困线标准只是作为一个基准来使用，并不能全面反映一个家庭是否真正贫困。
实际上，美国的贫困状况相当复杂，还涉及到诸多其他因素，例如地理位置、教育水平、就业机会、健康状况等等。
此外，还值得关注的是，由于COVID-19疫情的冲击，2024年以来，美国的贫困率有可能增加，因为许多人失去了工作、收入下降或者健康开支增加。
因此，贫困线标准也需要根据具体情况进行动态调整，以反映时代的变化和特殊情况的影响。
总的来说，美国贫困线标准提供了一个衡量贫困状况的参考，但实际中仍需要结合其他因素和具体情况来进行综合评估和分析。
政府和社会组织应该进一步努力，通过采取有效的政策和措施，减少贫困并改善贫困人口的生活状况。

美国人口普查American census
For years, Jorge DelPinal's job as assistant chief of the Census Bureau's Population Division was to fit people into neat, distinct racial and ethnic
boxes: white, black, Hispanic, Asian or Native American. As the son of an
Anglo mother and a Hispanic father, however, he knew all along that the task
was not always possible.
For the 2000 decennial census, that will no longer be the case. For the first
time, the census forms will allow people to check off as many races as apply.
As a result, the Census Bureau should obtain a better picture of the extent of intermarriage in the United States. In the absence of such a direct method,
a few years ago veteran demographer Barry Edmonston used sophisticated mathematicalmodeling techniques to calculate how intermarriage is changing the face of the United States as part of an immigration study he directed for the National Research Council of the American Academy of Sciences. His research was summarized in a report entitled The New Americans: Economic, Demographic and Fiscal Effects of Immigration. But as the Canadian-born, white husband of sociologist Sharon Lee,a Chinese-American, Edmonston really needed no computer to understand thetransformation under way in this society. He and his family
are living, breathing participants. The face of America is changing -- literally.
As President Clinton has said, within 30 or 40 years, when there will be
no single race in the majority in the United States. But afoot behind the scenes
is another trend that, if handled carefully, could bring the country closer
together rather than drive it apart. This quiet demographic counter-revolution
is a dramatic upsurge in intermarriage. Edmonston's study projected that by 2050, 21 percent of the U.S. population will be of mixed racial or ethnic ancestry, up
from an estimate of seven percent today. Among third-generation Hispanic and Asian Americans, exogamy-marriage outside one's ethnic group or tribe-is at least
50 percent, he and others estimate. Exogamy remains much less prevalent among African Americans, but it has increased enormously, from about 1.5 percent in
the 1960s to eight to 10 percent today. Such a profound demographic shift
could take place while no one was watching because, officially, no one was watching. Federal agencies traditionally collected racial data using a formula'
one person, one race' similar to the time-honored voting principle. Thus, the Census Bureau could estimate that on census forms no more than two percent of
the population would claim to be multiracial. In the absence of a more straightforward count, no one could know for sure what the demographics are.。
