The world has reached a somewhat     1     (worry) demographic (人口统计学的) milestone. A spokesperson said the U. S. Census Bureau (人口统计局) estimated that the     2     (globe) population surpassed 8 billion on the 26th of September.     3    , he said this was a very rough guess and the precise day could be a month or two either side of this date. The world population had doubled between 1960 and 2000, and     4     (grow) from 6 billion to 8 billion in the past two decades. The rate of growth is slowing     5     birth rates are falling in many nations.

According to the Census Bureau, trends of longer lifespans and lower birth rates result     6     the slowdown in population growth. However, it forecast that the population would reach 10. 2 billion in 2060. It said: “The world population is projected to keep growing despite     7     (decline) birth rates. In fact, we estimate     8     number of infants already peaked in 2017. Instead, population growth in the future will come from larger groups of people at adult ages.” It added: “Population growth is the result of birth rates, mortality (死亡率), migration and the share of the population at certain ages. Nearly three quarters (74 per cent) of the earth’s population     9     (resident) in countries     10     birth rates are around or below the replacement level.”

3 . In a policy address to lawmakers, Japan’s Prime Minister, Fumio Kishida, said the country’s population problem was a case of solving the issue “now or never”, and that it “simply cannot wait any longer because it can affect social functions”.

“In thinking of the sustainability and inclusiveness of our nation’s economy and society, we place child care support as our most important policy,” he said, adding that he wants the government to double its spending on child-related programs, and that a new government agency would be set up in April to focus on the issue.

Japan has one of the lowest birth rates in the world, and it recorded fewer than 800,000 births in 2022 for the first time since records began in 1899. The country also has one of the highest life expectancies in the world; in 2020, nearly one in 1,500 people in Japan were age 100 or older, according to government data.

These trends have driven a growing population problem, with a rapidly aging society, a shrinking workforce and not enough young people to fill the gaps in the stagnating (停滞) economy. The country’s high cost of living, limited space and lack of child care support in cities make it difficult to raise children, meaning fewer couples are having kids. Experts point to the pessimism young people in Japan hold towards the future, many frustrated with work pressure and economic stagnation.

How about other parts of East Asia? South Korea recently broke its own record for the world’s lowest birth rate, with data from November 2023 showing a South Korean woman will have an average of 0.79 children in her lifetime — far below the 2.1 needed to maintain a stable population. Japan’s birth rate stands at 1.3, while the United States is at 1.6. Meanwhile, China’s population shrank in 2022 for the first time, adding pressure to its economic growth.

5 . Falling birth rates are a major concern for some of Asia’s biggest economies. Government s in the region are spending hundreds of billions of dollars trying to reverse the trend. Will it work?

Japan began introducing policies to encourage couples to have more children in the 1990s. South Korea started doing the same in the 2000s, while Singapore’s first fertility (生育) policy dates back to 1987. China, which has seen its population fall for the first time in 60 years, recently joined the growing club.

While it is difficult to quantify exactly how much these policies have cost, South Korean President YoonSuk-yeol recently said his country had spent more than $200bn (£160bn) over the past 16 years on trying to boost the population. Yet last year South Korea broke its own record for the world’s lowest fertility rate, with the average number of babies expected per woman falling to 0.78. In neighbouring Japan, which had record low births of fewer than 800,000 last year, Prime Minister Fumio Kishida has promised to double the budget for child-related policies from 10tn yen ($74.7bn; £59.2bn).

Having a bigger population who can work and produce more goods and services leads to higher economic growth. And while a larger population can mean higher costs for governments, it can also result in bigger tax revenues (税收). Also, many Asian countries are ageing rapidly. Japan leads the pack with nearly 30% of its population now over the age of 65 and some other nations in the region are not far behind. Compare that with India, which has just overtaken China as the world’s most populous nation. More than a quarter of its people are between the age of 10 and 20, which gives its economy huge potential for growth. And when the share of the working age population gets smaller, the cost and burden of looking after the non-working population grow. “Negative population growth has an impact on the economy, and together with an ageing population, they won’t be able to afford to support the elderly,” said Xiujian Peng of Victoria University.

6 . In 2050, one in four people will be over 60 in the Asia-Pacific region. Are countries there prepared to fully address the needs of older persons so that they age with dignity?

In the past, senior citizens might have been supported by their families and communities. Yet times are changing.

    1     Meanwhile, more and more governments are wrestling with increasing healthcare costs and a decreasing workforce.

More than ever, there is an urgent need for policy reform in addressing population aging. This must be driven by a shift in mindset to turn the challenges into a demographic opportunity.

    2     More and more people are living longer due to the advancements in health, nutrition, economic and social well-being.     3     This is due to a variety of reasons such as challenges in striking a work-life balance to not being able to afford having more children. However, low fertility and longer life expectancy are not the problem. The real problem is not being ready to face this rapidly changing demographic shift.

It is noteworthy that, in the Asia-Pacific, with more than half of the older population being women, it is crucial to adopt a life-cycle approach to population aging, grounded in gender equality and human rights. Investing in each stage of life determines the path of a woman’s life course. When a girl has access to quality education, it helps her make informed decisions about life-changing matters.     4    

While there is no single comprehensive policy that can address population aging, we need to take action now.     5     In so doing, countries in the Asia-Pacific region can hope for, and achieve, a better future for all, where no one is left behind.

7 . On November 15 in 2022, the United Nations (UN) reported that the number of people on Earth had grown to eight billion (8,000,000,000). That came just 11 years after the world reached seven billion people. The world faces challenges ahead as the population continues to grow.

The world’s population – the number of people on the planet – has grown rapidly over the last 200 years. In 1805, for the first time ever, the Earth had a billion people on it. It took over 100 years for that number to double to two billion. In less than 50 years, it had doubled again to four billion. Now, again in less than 50 years, the number has doubled once more to eight billion.

How fast local populations are growing depends a lot on where you are in the world. Typically, as countries become richer, their population growth slows. In some countries, like Japan, the number of people is actually shrinking. The greatest population growth these days is found in Asia and Africa.

Currently, China, with a population of 1.4 billion, is the country with the most people. That’s expected to change in the next year, when experts say India will pass China as the country with the world’s largest population. Other countries where rapid growth is expected through 2050 are the Democratic Republic of the Congo, Egypt, Ethiopia, Nigeria, Pakistan, the Philippines, and Tanzania.

8 . The world’s population reached five billion on the day I was born. That was in Indonesia back in 1987, and my parents was shocked that there were so many people on the planet.     1     In October 2011, the seven billionth baby was born, and experts predict that there will be ten billion of us before the end of this century.

    2     If you said “hello to a different person every second, it would take you 222 years to greet everyone on the planet. If seven billion people made a human chain with their hands, the chain would go to the moon and back nine times.

The human population has never been bigger, but in some ways the planet seems to begetting unbelievably smaller. In the past, travellers from Europe to Indonesia spent months at sea. Now you just have to sit on a plane for a few hours. When you arrived in another country a hundred years ago, you saw unfamiliar styles of clothing and buildings and discovered a completely different culture. In many places today, clothing and new buildings are very similar, and people enjoy the same things.     3    

Even the languages that we use are becoming more global. There are around seven thousand languages in use today.     4     I grew up in a small village where everyone spoke Baras, one of Indonesia’s local languages. Today, like most of the youth from my village, I live in the capital, Jakarta, and speak Indonesian there. The only regular Baras speakers at present are the older people who have stayed in the country, so the language is threatened with extinction.

Do you know the nickname of America? A look at the history of the United States indicates that so far this country     1     (call) “a melting pot”, in which various immigrants and ethnic groups have learned to work together to build     2     unique nation. So who are the real Americans? The answer is that any and all of them are! And you, no matter     3     you come from, could also become an American if you want. Then you would become another    4     (add) to America’s wonderfully rich “nation of immigrants”.

The United States is     5     (current) shifting from being a nation of immigrants of mainly European origins to one of immigrants from other parts of the world. They hope to escape     6     (economy) hardship in their native countries. They desire     7     (seek) a better education and a better life in America. Although there are frequent     8     (conflict) between the cultures they have brought with them from the “old country” and those found in American, most immigrants have learnt to adjust     9     and love their adopted land.

Over time, Americans have learned much from the customs and ideas of the immigrants. In other words, immigrants have a huge impact on American society,     10     (enrich) American life greatly.
