the aging of world population (1950-2100)译文简介
网友：巴西老龄化的速度真的非常快，对于一个60年代人口结构还非常年轻的国家来说，巴西现在的生育率真的是太低了（只有1.7），如果巴西老龄化速度没有那么快的话，现在巴西人口可能会更多一些，有可能巴西人口会达到2.4亿

很赞 (1)
brazil has aged faster than other south american countries
巴西是南美老龄化速度最快的国家
yep, that's interesting, cause the brazilian population was always really young.
是的，这很有趣，因为巴西过去人口一直都很年轻
brazil aged extremelly fast, it's fertility rate is incredible low (1,7 today) for a country that had a super young population in the 60s, if brazil's population haven't aged that fast it's population today could have been even bigger, probably reaching the 240 million today.
巴西老龄化的速度真的非常快，对于一个60年代人口结构还非常年轻的国家来说，巴西现在的生育率真的是太低了（只有1.7），如果巴西老龄化速度没有那么快的话，现在巴西人口可能会更多一些，有可能巴西人口会达到2.4亿
@minionslegion3399 unfortunately brazil didn’t invest alot in its young population, unlike south korea. brazil could have become a superpower.
遗憾的是，巴西没有像韩国那样大力投资本国的年轻人口。巴西本来是可以成为超级大国的
@gabrielpr03 south korea is the fastest aging country in the world, despite the investment in youth.
虽然韩国在年轻人身上进行了大力投资，但是韩国是世界上老龄化速度最快的国家
@espopovicxd the difference is just that sk will have a much richer aging population than brazil
区别在于韩国老龄人口要比巴西富裕的多
it even aged faster than the usa lol
巴西老龄化的速度甚至比美国还要快，哈哈
@dominusnoobus1589 i think immigration explains that
我认为这是因为美国有外来移民
in italy population is too old and it’s declining fast. our fertility rates are extremely low :(
意大利人口太老了，而且意大利人口正在快速下滑。我们的生育率真的是太低了
владислав пронин thr u.k. has quite a high fertility rate for a white nation
对于一个白人国家来说， 英国的生育率真的相当高。
@scottwhitley3392 this is because britain has a lot of immigrants.
这是因为英国有很多外来移民
same with croatia we lost 400k people in 10yr
克罗地亚也是如此，我们十年间减少了10万人口
that's a good thing, lesser population means higher wages, we are not living in 18th century now countries don't need huge population to support industries in future robot's will replace humans so majority of young population will be of no use
japan's economy bigger than entire africa
人口减少是一件好事，人口越少意味着工资就会越高，现在已经不是18世纪了，未来的工业发展不再需要那么多的人口了，机器人会取代人类，所以大部分年轻人将会变得毫无用武之地。
日本的经济规模比整个非洲都要大
@sl-abcd it's a worse thing.
人口减少会让情况变得更加严重
@danialsowack1401 no that's a good thing population decline means higher value of human life, earth can't support luxurious life of 9 billion people
japan economy=> $5 trillion
combined gdp of africa => $3 trillion
africa's population is 14 time's higher than japan's population quality is more important than quantity
不，人口减少是一件好事，人口减少意味着个人生命的价值会变高。地球无法让90亿人都过上奢侈的生活
日本的经济规模至少在五万亿美元
而整个非洲加起来也才不过3万亿美元
而非洲人口是日本的14倍，质量要比数量更加重要
sl-abcd old people is less effective to work… which wouldn’t make the economy grow
老年人的工作效率没有年轻人高，这会阻碍经济的发展
gianpieronuzzovillegas8618 yes you are right, as of now we need young people to support economy but this will not last for long, within next 1-2 decade artificial intelligence will replace humans
是的，你说的不错，目前我们依然需要年轻人口来支持经济的发展，但是这种情况不久之后就会发生变化，未来一二十年，人工智能就会取代人类

dont worry ur former colonial somalia has the youngest 14-20ages in the world so i guess we gonna help u guys
不要担心，你们的前殖民地索马里是世界上最年轻的国家，我们的平均年龄在14到20岁之间，所以我想我们会帮助你们的
@sl-abcd no. a collapsing population will mean less goods and services being produced, and more people having to live a semi-agrarian lifestyle to survive. when most people are elderly, pension pots disappear, businesses dies and economy in permanent recession, then you will see a collapse in wages. it will be another great depression, but this time without young people to bail out countries and rebuild the world.
in 2100, only countries that can attract young immigrants will be able to keep their economies going. majority of countries will be in a never-ending recession.
不，人口减少不是一件好事。人口锐减将意味着提供的产品和服务数量的减少，为了维持生活，更多的人将不得不过上半农耕的生活方式。大部分人老了之后将领不到养老金，企业倒闭，经济会陷入永久性的衰退。但这一次不会再有年轻人出来拯救国家，重建世界了。
到2100年，只有那些能够吸引年轻移民的国家才能让经济继续运转下去。大部分国家将陷入无休止的衰退之中。
@ilicdjo italy can have filipinos. they are catholic so it may be easier for them to integrate with italy. philippines has a lot of young people.
意大利可以吸引菲律宾移民。菲律宾人都是天主教徒，所以他们可以更容易融入到意大利社会之中。菲律宾拥有很多年轻人口。
@ilicdjo muslims started to have less children in italy. it is about welfare. yes immigrants get more social help than italian citizens ,true. but once they become citizens they face same problems of italians .
意大利的穆斯林都开始不热衷生孩子了。这和福利有关。是的，移民可以比意大利公民得到更多的社会帮助。但是一旦这些移民成为了正式公民，他们就会面临和意大利人一样的问题。
@sl-abcd japan's economy is stagnating not growing, their gdp has been stuck at $5 trillion since 1995, and because of their shrinking population and workforce, they have problems with deflation. this has resulted in the lowest wage growth of any industrialized country. they also have the debt to gdp ratio at over 200% which makes it extremely difficult for the japanese to borrow their way out of any financial crisis. japan is basically stuck between a rock and a hard place, with extremely low economic or wage growth, rapidly shrinking workforce and increasing competition from other industrialized asian countries. the situation is so bad that the imf expects india to surpass japan before 2030, even with the economic slowdown in india. japan may be wealthier than africa, but that country is actually an example of why rapid depopulation is bad
日本的经济停滞不前，没有任何增长，自1995年以来，日本gdp一直停留在5万亿美元，这是因为日本的人口和劳动力在不断萎缩，他们有通货紧缩的问题。这使得日本成为工业国当中工资增长幅度最低的国家。日本债务占gdp的比重超过了200%，这使得日本很难通过借贷来摆脱金融危机。日本经济和工资增长率极低，劳动力极度萎缩，而且还要面临来自亚洲其他工业国不断加剧的竞争，日本现在基本上处于进退两难的困境之中。日本的情况非常糟糕，国际货币基金组织预测即便印度经济增速放缓，也能在2030年之前超过日本。日本或许比非洲更加富裕，但是日本这个例子恰恰说明了为什么人口快速减少不是一件好事的原因。
@u9date fact of the matter is that immigration will only temporarily increase population growth. poorer countries have falling fertility rates too you know.
事实上，移民只能暂时提高人口增速。你要知道，贫穷国家的人口生育率也在减少
because in italy we have an high life expectancy... like japan and spain
因为和日本西班牙一样，我们意大利的预期寿命也很高
because of high life expectancy and low fertility rate
因为预期寿命长，生育率低
an median age is a key indicator of a country's wealth. the wealthier and more developed a country is, the longer people live, and so the median age of that country also rises.
中位数年龄是衡量一个国家富裕程度的关键指标。越富裕，越发达的国家，人们的寿命就会越长，国家中位数年龄也就会越高。
south asia historically had huge population because of abundant water, fertile land. same is the case with china.
由于水资源丰富，土地肥沃，南亚地区历来人口众多。中国同样也是如此
we're really in a tough situation in the modern day. unrestrained population growth will further harm our environment, make resources scarcer. while an ageing population will result in economic stagnation/decline, collapse of welfare systems, and perhaps less innovation and advancement. the only way to maintain stability is to either maintain world population or allow it to grow very slowly
我们现在的处境真的很艰难。无节制的人口增长将会进一步损害我们的环境，让资源变得更加紧缺。人口老龄化将会导致经济停滞/衰退，福利制度崩溃，可能还会阻碍创新和发展。维持稳定的唯一办法就是要么维持世界人口数量，要么让世界人口缓慢的增长

after the 2040-2050, the world will stay in the worst crisis of history
在2040-2050年之后，世界将陷入有史以来最严重的危机之中
don't worry, most nations will face declining population in next 2 decades. already india is on the brink of fertility rate 2.1, so below it will result in declining population. the total world population might reach 10 billion and then would decline rapidly.
不用担心，未来20年，世界上大部分国家将会面临人口减少的情况，印度人口出生率已经在2.1左右，只要低于2.1，那么人口就会减少。世界总人口或许会达到100亿，之后将快速下滑。
by 2100, albania will be the oldest with a median age of 66
到2100年，阿尔巴尼亚的中位数年龄将达到66岁，将成为世界上最老的国家
italy, spain, japan people is 50 years old when niger people is like 15 years old, what a huge difference
意大利，西班牙，日本的中位数年龄已经达到50岁了，而尼日尔的中位数年龄只有15岁，差距实在是太大了
cuz poverty
因为贫穷
same as somalia like 80per of the population are younger than 20
索马里也一样，索马里80%的人口都不到20岁
@prideium9001 nigeria and mexico use to have the same population. mexico embraced family planning while nigeria did not. i'll take mexico. nigeria is headed toward a cliff which will lead to poverty and violence.
尼日利亚和墨西哥之前的人口差不多。后来墨西哥实行了计划生育政策，而尼日利亚却没有。如果要在这两个国家里面选择一个的话，我会选择墨西哥。尼日利亚正在走向暴力和贫穷的深渊。
damn, africa is a really young continent. the median age of some african countries are less than half the median age of most european countries. how do they find enough jobs for those young people?
非洲真是一块年轻的大陆。一些非洲国家的中位数年龄竟然连大部分欧洲国家的一半都不到。他们要如何为这些年轻人口提供足够的工作岗位呢？
those people migrate to other countries.
非洲人会移民到其他国家。
@dukes1993724 the vast majority will never leave the continent
绝大部分非洲人永远都不会离开非洲大陆
they will leave east africa and go up to europe and asia.
他们会离开东非，移民到欧洲和亚洲
by the year 2070, the only countries with relatively young populations outside of africa is papua new guinea and iraq.
到2070年，非洲以外，人口相对年轻的国家只有巴布亚新几内亚和伊拉克
