事关美国前途：2021年美国人口增长率创历史新低
圣诞节快到了，先给大家讲一件比较轻松好笑的事，祝大家圣诞快乐，身体健康，心情愉悦。
据报道，香港歌神张学友前天在记者会上说疫情期间仍会坚持练歌，结果被邻居投诉了，让他对自己的歌声产生了怀疑。“我每天在家至少练一小时，通常选一些平时不敢唱，难度比较高的歌来练，可能在自己房间特别放松，竟然收到邻舍投诉！我唱歌不是很好听吗？为什么会有人投诉？向管理员打听，原来邻居是印度人，证明我还不够红，还需继续努力。”
同样，如果你不喜欢我们每天的推文，说明我们做得不够好，还需继续努力！
下面回到严肃的正题，事关美国前途：2021年美国人口增长率创历史新低，新冠疫情、移民减少和老龄化是三大原因。
美国人口普查局2021年12月21日表示，由于新冠疫情加剧了美国近年来经历的较为低迷的人口增长，美国2021年的人口增长速度比有记录以来的任何其他年份都要慢。
人口普查局周二说：“增长速度缓慢可归因于移民减少，生育率下降，以及部分由于新冠（COVID-19）大流行导致的死亡率上升。”
2021年是自1937年以来美国人口首次增长低于100万人，是自1900年人口普查局开始进行年度人口估计以来的最低人口增长率。
根据美国人口普查局周二发布的2021年人口估计，美国人口在过去一年（2020年7月1日到2021年7月1日）增加了392,665人，增幅为0.118%。
几年来，人口增长放缓一直是美国的一个趋势，这是生育率下降和国际净移民减少的结果，加上人口老龄化导致的死亡率上升。
在2020年和2021年之间，美国33个州的人口有所增加。17个州和哥伦比亚特区的人口减少。周二公布的数据显示，在这18个人口减少的地区中，有11个地区的人口损失在1万人以上。
"除了过去几年人口增长放缓到历史最低水平外，20世纪最慢的增长速度是在西班牙流感和第一次世界大战期间的1918-1919年，"人口普查局人口估计处处长Luke Rogers说。
数据显示，自2020年4月1日（人口普查日）以来，全国人口从331,449,281人增加到331,893,745人，增幅为0.134%。
根据美国疾病控制和预防中心的数据，美国因冠状病毒爆发而导致的官方死亡人数是迄今为止世界上最高的，该国有超过80万人因该疾病死亡。希望美国早日走出疫情，人口增长恢复正常。
COVID-19, Declining Birth Rates and International Migration Resulted in Historically Small Population Gains
LUKE ROGERS
DECEMBER 21, 2021
The U.S. population grew at a slower rate in 2021 than in any other year since the founding of the nation, based on historical decennial censuses and annual population estimates.
The U.S. Census Bureau Vintage 2021 Population Estimates released today show that population grew only 0.1% and that the COVID-19 pandemic exacerbated the slower growth the country has experienced in recent years.
Apart from the last few years, when population growth slowed to historically low levels, the slowest rate of growth in the 20th century was from 1918-1919 amid the influenza pandemic and World War I.
The year 2021 is the first time since 1937 that the U.S. population grew by fewer than one million people, featuring the lowest numeric growth since at least 1900, when the Census Bureau began annual population estimates.
Apart from the last few years, when population growth slowed to historically low levels, the slowest rate of growth in the 20th century was from 1918-1919 amid the influenza pandemic and World War I.
Slower population growth has been a trend in the United States for several years, the result of decreasing fertility and net international migration, combined with increasing mortality due to an aging population.
In other words, since the mid-2010’s, births and net international migration have been declining at the same time deaths have been increasing. The collective impact of these trends is slower population growth.
This trend has been amplified by the COVID-19 pandemic, resulting in a historically slow population increase in 2021 (Figure 2).
Today’s release of the Vintage 2021 estimates includes a blog and America Counts stories that explain how the impacts of COVID-19 and other unique challenges were accounted for in this year’s estimates, including more detail on net international migration and Puerto Rico migration.
The Census Bureau will continue to release more details from Vintage 2021 next year, including more comprehensive data and analyses on the distinctive trends in this series of estimates.
