So let's start with a few problems.
那么我們就從一兩個(gè)問(wèn)題入手吧。
Right now, a billion people are chronically hungry.
目前，有十億人口長(zhǎng)期處于饑餓狀態(tài)。
That means they wake up hungry, they are hungry all day, and they go to sleep hungry.
那意味著他們醒來(lái)時(shí)餓著肚子、白天餓著肚子、晚上睡覺(jué)時(shí)餓著肚子。
A billion people are living in slums, not the same billion people, but there is some overlap.
有十億人生活在貧民窟，雖然與上面提到的十億人不相同，但它們之間有重疊。
Living in slums means they don't have infrastructure to take the garbage away, they don't havesecure water supplies to drink.
生活在貧民窟意味著他們沒(méi)有清理垃圾的基礎(chǔ)設(shè)施，沒(méi)有沒(méi)有安全的飲水供應(yīng)。
Nearly a billion people are illiterate.
有近十億人是文盲。

You can't read the labels on the bottles in the supermarket, if you can get to a supermarket.

Two-thirds of those people who are illiterate are women and about 200 to 215 million womendon't have access to birth control they want, so that they can control their own fertility.
女性占了十億文盲人口的三分之二。，大約2至2.15億的女性接觸不到她們想要的避孕方法，這樣她們就可以控制自己的生育能力。
This is not only a problem in developing countries.
這不僅僅是發(fā)展中國(guó)家才有的問(wèn)題。
About half of all pregnancies globally are unintended.
全世界大約有一半的懷孕是意外懷孕。
So those are examples of population problems.
以上是一些典例的人口問(wèn)題。
Demography gives you the tools to understand and to address these problems.
人口統(tǒng)計(jì)學(xué)為你提供理解和解決這些問(wèn)題的工具。
It's not only the study of human population, but the populations of non-human species, including viruses like influenza, the bacteria in your gut, plants that you eat, animals that youenjoy or that provide you with meat.
它不僅僅研究人口數(shù)量，還研究流感病毒、腸道菌群、人類食用的植物、人類喜歡的動(dòng)物或?yàn)槿祟愄峁┤忸惖膭?dòng)物等非人類物種的數(shù)量。
Demography also includes the study of non-living objects like light bulbs and taxi cabs, andbuildings because these are also populations.
人口統(tǒng)計(jì)學(xué)的研究還包括諸如電燈泡、出租車和建筑物等無(wú)生命體的研究，因?yàn)樗鼈兺瑯哟嬖跀?shù)量。
It studies these populations, in the past, present and future, using quantitative data andmathematical models as tools of analysis.
它研究這些物體過(guò)去、現(xiàn)在和將來(lái)的數(shù)量，使用定量數(shù)據(jù)和數(shù)學(xué)模型工具進(jìn)行分析。
I see demography as a central subject related to economics.
我把《人口統(tǒng)計(jì)學(xué)》看成是與《經(jīng)濟(jì)學(xué)》密切相關(guān)的核心科目。
It is the means to intervene more wisely, and more effectively in the real world, to improvethe well-being, not only of yourself—important as that may be—but of people around you andof other species with whom we share the planet.
它是現(xiàn)實(shí)世界中更明智、更有效的干預(yù)手段，不僅能提升你自己的幸福，還能提升你身邊的人以及和我們共同生活在地球上的其他物種的幸福。
