Key Issue #4

Thomas Malthus was one of the first to see the drastic increase of the human population and worry about how it may affect future generations. He argued that the human population would get so big that there would not enough food to feed the population. However, he never thought about the technology that would be produced between his time and now. In today's world we have harvesters, planes, and an industrialized society that helps produce enough food and supplies to support the human population. Many others have had their own ideas about this subject. Julian Simon argued that our resources will grow with time, which was proven correct. He also believed that the human mind was the ultimate resource. Esther Bosenup believed that population growth spurs technological innovation. Karl Marx believed that moral restrain was not the only acceptable preventive check. With the rapid increase of the human population over the past century, more and more countries are trying to find ways to decrease their population. Countries such as China only let parents have a child if they have a permit, however; couples that want to have a second child must pay a family-planning fee. Countries are also trying to get more and more women in schools so that they will learn employment skills and gain more economic control over their lives. These countries are slowly having more death rates than birth rates. Because of these country's populations declining, scientists think that a new stage should be made called stage five. This is when after the crude birth rate is equal to the crude death rate, the crude birth rate starts to decline more while the crude death rate stays the same. This causes the country's overall population to decrease and the world's population to decrease.




Has China's one-child policy worked?

In the first of a series of pieces on China's one-child policy, the BBC's Michael Bristow looks at whether the country's controversial regulations are working.

Chinese child
Some parents in China are happy with one child
China's family planning policy has prevented 400 million births, officials say.
Since the regulations were introduced in 1978, China has kept its population in check using persuasion, coercion and encouragement.
And it looks likely that, nearly 30 years after the policy was first introduced, it will not be relaxed to allow couples to have more children.
Many Chinese and foreign academics believe this is a mistake and will result in a number of serious demographic problems in the future.
At a press conference earlier this year, Chinese officials were keen to declare the controversial policy a success.
"Because China has worked hard over the last 30 years, we have 400 million fewer people," said Zhang Weiqing, minister in charge of the National Population and Family Planning Commission.
"Compared with the world's other developing countries with large populations, we have realised this transformation half a century ahead of time."
A team of independent Chinese and foreign academics, who this year completed what they say is the first systematic examination of the policy, agree that China has managed to limit its population growth.
But team leader Wang Feng, of the University of California, Irvine, says this reduction is mainly due to a fall in the fertility rate in the 1970s, rather than any more recent initiatives.

It wouldn't matter what my financial situation was or what the government regulations were, I'd still only want one child
Zhao Hui, mother
During the 1970s, China began encouraging delayed marriages, longer intervals between births and fewer children.
"The total fertility rate - the number of children a woman is expected to have in her lifetime - was reduced from over five to slightly over two," Prof Wang says.
All this happened before the current family planning policy was introduced in 1978.
'Too busy'
The fall in fertility rates is also, at least partly, due to improving social and economic circumstances.
In other East Asian countries, such as Thailand and South Korea, modernisation has led to women having fewer children, and yet these countries do not have strict family planning policies.

Graphic
But Professor Wang does admit that China's family planning policies since 1978 have helped reduce the fertility rate further and contributed to a change in attitudes.
"A lot of people simply don't want that many children. People have accepted the policy," he says.
This is particularly true in urban areas, where most couples interviewed by the BBC say they are happy with just one child.
Beijing mother-of-one Zhao Hui, who has a four-year-old daughter called Zhang Jin'ao, says she has never wanted more than one child.
"One child is enough. I'm too busy at work to have any more," says the 38-year-old, who works in the housing sector.
"It wouldn't matter what my financial situation was or what the government regulations were, I'd still only want one child," she adds.
Most of her friends, she says, think the same way.
Forced abortions
But there is a more sinister aspect to this policy, which is sometimes employed to make women less willing than Ms Zhao accept the rules.
Activist Chen Guangcheng was sent to prison last year for exposing what he says were over-zealous health workers in Linyi city, Shandong Province.

Chinese children
China has rejected calls to change its one-child policy
He says they illegally forced women to have late-term abortions and be sterilised.
China also faces profound and widespread demographic problems because of its family planning rules, according to some.
Chinese officials say the current fertility rate is between 1.7 and 1.8 births per woman, well below the 2.1 births needed to keep the population at a stable level.
Overseas experts dispute this figure; they say the fertility rate is even lower and stands at 1.5.
This will result in an increasing proportion of older people, a smaller workforce to look after them and a disproportionate number of boys to girls.
There are other problems too. China might have restricted its population growth, but this has not always helped solve wider problems, as was envisaged when the policy was first introduced in 1978.
Reducing the number of people, for example, does not automatically help the environment, as China has found.
Prof Wang says the policy needs to be relaxed if China is to solve some of these problems.
There are at least a few people inside China who agree with that assessment.
During this year's parliamentary session in March, 29 members of the Chinese People's Political Consultative Conference, a government advisory body, suggested allowing couples to have two children.
But that suggestion will probably fall on deaf ears, at least until the end of the government's current five-year plan, which ends in 2010.
At the press conference earlier this year, Minister Zhang said there was not the "slightest doubt" about the need to continue with the policy.
China might face serious consequences because of that attitude in the not-too-distant future.

Key Issue #3

Every country today is atleast past stage 1. Most countries are in stages two and three, and more developed countries such as the United States are in stage four. The countries that are in stage four have successfully achieved a demographic transition, which is the change from a high crude birth rate, high crude death rate, and low natural increase rate, to a low crude birth rate, low crude death rate, a low natural increase rate, and a higher total population. Around 8000 B.C., when every country was in stage one, the agricultural revolution began to take its role in human life. People were settling in permanent settlements to plant their crops, instead of migrating where there were wild animals to hunt. Every country has been in stage one longer than any other stage. Many countries in Africa are in stage two of the demographic transition. Their dependency ratio is extremely high because of their low percentage of adults that live through childhood. In this stage, the amount of births are extremely high and the crude death rate drops drastically compared to the crude birth rate. Countries that achieve going into stage two have had some sort of change in their economy. One example is of the United States and England, both went through an industrial revolution and a medical revolution. This changed the way that people lived either by more knowledge of their medical supplies or being smarter on how they acted towards things such as sexual intercourse. Also, their new way of manufacturing goods through their industrial revolution helped them export and import goods and services faster and cheaper than before. In stage three, a country's crude birth rate will descrease while the death is also decreasing. this is slowly decreasing the natural increase rate, but the population for these countries is still growing. In stage four of the demographic transition, a country's crude birth rate has met up with the crude death rate and they are about equal. This causes the natural increase rate to still decrease to zero and causes a term known as zero population growth to occur. This means that the total fertility rate declines all the way until the natural increase reaches zero. Population pyramids are used to measure out the percentage of each age group in a certain area. This age distribution may be because of a college in the main area or where the area may be located. These charts also help in labeling the sex ratio between males in females. In the United States, males outnumber females 105:100 under age 15, however; after age 40, females start to outnumber males. However, in countries like Japan, the population is shrinking instead of growing. This will become a huge problem because they will have too many elderly and not enough to work and pay for the elderly to be taken care of.



Upside Down: The Population Pyramid Problem

Today is Population Census Day in Japan. And while it comes around every five years in Japan, Friday’s survey could be the first to provide concrete, stark evidence of the country’s dramatic population shrinkage.
Every five years (compared with every ten in the U.S.), the Ministry of Internal Affairs and Communications attempts to find out — among other things — the names, ages, nationalities and employment conditions of everyone living in Japan. Any national census is a statistical goldmine, and this year’s survey will be studied closely by policymakers desperate to find a way to revive Japan’s stuttering economy in the face of unprecedented demographic shifts.

Japan’s census, which begins today, could provide the first concrete evidence of the nation’s shrinking population.
In the post-war boom years, Japan had a population pyramid that looked like Mt. Fuji, with a broad spread of younger generations at its base. Japan enjoyed a 15.3% increase in population from 1945-1950 and a virile average rise of 5.7%  in every survey after that until 1980. By the time of the last census in 2005, Japan’s population increase had shriveled to just 0.7% over the five years from 2000-05 (to 127.77 million). But breaking the figures down by the year within the survey period, the population actually fell by 20,000 in the last year of the survey (2004-05), the first drop since the end of World War II.
This year’s census will likely confirm that Japan’s population has entered a long phase of decline, as the country’s glacial but remorseless demographics — a rapidly aging society and a slowing birthrate -– start to flip over into an inverted pyramid and fundamentally alter the structure of its economy.
“The 2010 census will be the first to show an actual population loss (over the five years). We’ll be able to see that we’ve gone off the cliff.” says John Mock, a visiting professor at Temple University in Japan. “One of the things to look out for is whether the rate of depopulation is speeding up,” he says.
Japan’s population is forecast to shrink to just 95.15 million by 2050, according to the National Institute of Population and Social Security Research, and coping with that demographic time bomb is one of the key challenges facing the country. It’s a challenge exacerbated by Japan’s sluggish economy, entrenched deflation and weak employment conditions, which Prof. Mock says make it difficult to see just how the country will be able to sustain a growing population of over-65s.
“It will be interesting to see (in the results of the census) what young Japanese people are doing for a living,” he says, noting that the number of people choosing ‘other’ as their category of occupation in the census has grown over the last 20 years. That suggests a lack of stable jobs, and a rise in the number of people doing low-skilled, low-paid work (known as ‘freeters’ in Japanese).
“If you have people making good solid incomes for the next 30 to 40 years, then it makes the problems easier,’ says Prof. Mock.  “But if you have young people working in convenience stores, then their ability to carry the load is much weaker.”

Key Issue #2

Over the past few centuries, every country in the world has been increasing dramatically. This is causing the entire population of the world to grow at an alarming pace. The reason for this increase is because the crude birth rate is higher than the crude death rate. This is caused by an increase in medical knowledge that causes people to live longer and become more aware of different diseases. The natural increase rate in most countries has been increasing because of this relationship between the crude birth rate and the crude death rate. Over the past 50 years the doubling rate for most countries has increased their population by 4 times what they originally were in 1950! This is because the infant mortality rate in most of these countries is extremely high because of their medical knowledge. The only country out of the six countries in the graph that doesn't have a high life expectancy is Africa. However, the reason why their population is increasing is because of the total fertility rate on the continent. Most people in Africa still want a large family to increase the odds of one of their children to living on to adulthood. Most of the countries in Africa have a lack of medical knowledge that most of the world has today. This causes their life expectancy to drastically shrink and was and still is a huge problem in Africa.


Life Expectancy

Overview of Life Expectancy


Jun 14 2010
Life expectancy from birth is a frequently utilized and analyzed component of demographic data for the countries of the world. It represents the average life span of a newborn and is an indicator of the overall health of a country. Life expectancy can fall due to problems like famine, war, disease and poor health. Improvements in health and welfare increase life expectancy. The higher the life expectancy, the better shape a country is in.
As you can see from the map, more developed regions of the world generally have higher life expectancies (green) than less developed regions with lower life expectancies (red). The regional variation is quite dramatic.
However, some countries like Saudi Arabia have very high GNP per capita but don't have high life expectancies. Alternatively, there are countries like China and Cuba that have low GNP per capita have reasonably high life expectancies.
Life expectancy rose rapidly in the twentieth century due to improvements in public health, nutrition and medicine. It's likely that life expectancy of the most developed countries will slowly advance and then reach a peak in the range of the mid-80s in age. Currently, microstates Andorra, San Marino, and Singapore along with Japan have the world's highest life expectancies (83.5, 82.1, 81.6 and 81.15, respectively).
Unfortunately, AIDS has taken its toll in Africa, Asia and even Latin America by reducing life expectancy in 34 different countries (26 of them in Africa). Africa is home to the world's lowest life expectancies with Swaziland (33.2 years), Botswana (33.9 years) and Lesotho (34.5 years) rounding out the bottom.
Between 1998 and 2000, 44 different countries had a change of two years or more of their life expectancies from birth and 23 countries increased in life expectancy while 21 countries had a drop.

Key Issue #1

The population in our world today is spread out unevenly with the amount of people in each country. Scientists use demography to help explain why the populations are what they are in each country. Most people today live within 300 miles of the ocean and low-lying areas with fertile soil. Countries in East Asia have thrived off of these living conditions because of their planting of rice. Without the fertile soil or water to grow this crop, countries such as china would lose its main food supply. However, over the past century more and more people have grown accustomed to an industrial lifestyle. Through the perspective of globalization, the agricultural density has been slowly diminishing because of the increasing shortage of farmers in each country. With the growing trend of cities and buildings sprouting up everywhere, the agricultural density has been drastically decreasing because of less and less amount of space in a certain region. However, this causes the physiological density to grow because of the increased amount of jobs in one area. With all of these different things adding up, overpopulation has become an increasing problem in our world today. Countries such as Japan have faced this problem with overcrowded subway stations and hard to find parking spots for cars. The ecumene has been increasing over the past few centuries, however; a lot of land on earth is still being used for farming in different countries. Many countries in South Asia and Southeash Asia are still using farming as their main way of life. Only about a fourth of the population is in an urban area and the rest are using rivers and wetlands to grow their crops. However, land that is too harsh to grow crops on is not used in the world, such as dry lands, cold lands and some high lands. In the world today, most of the world's population is distributed in Asia, Europe and the United States. These countries are where we get most of our workforce, and goods from to be used around the world.


Japan: Overcrowded from Cradle to Grave

Tokyo reigns as the world's largest city. The estimated population of 35 million in the Greater Tokyo Metropolitan Area gives new meaning to the word "overcrowded". With so many people crammed cheek by jowl, one might expect chaos and crime on a Lagos-ian scale, but no. Amazingly, and without the need for martial law, Tokyo works very well indeed. Crime is low by western standards, services are reliable and the infrastructure is the envy of most other cities. You won't find much peace & quiet in Tokyo; what you WILL find is a city that ticks like clockwork through the combined efforts of its people.
Sea of umbrellasSea of umbrellas
Tokyo was founded over 400 years ago but very little of the old town remains. A catastrophic earthquake in 1923 and the devastation wrought by World War II resulted in the city being rebuilt to modern standards. Wide streets that work WITH the city's infrastructure, not against it, funnel hundreds of thousands of people to and from major train stations. Overcrowded, yes, but the streets of Tokyo, Osaka and other Japanese cities are rarely prey to pedestrian gridlock.
"EEK!"... Sorry lady, just doing my job!"EEK!"... Sorry lady, just doing my job!
Like most metropolitan centers, Tokyo is a working city and the workers have to come from somewhere - and go home again at the end of each working day. They do this, for the most part, using the renowned Tokyo subway system. Multiple lines, color-coded for ease of use even by foreigners, crisscross the city from beneath like some bizarre subterranean spider web. Morning and evening rush hours are busiest, to the point where gloved and uniformed "people pushers" ensure that the doors of the overcrowded cars close smoothly.
At least it's quiet...At least it's quiet...
Alas, Japan's long-suffering citizens gain no respite from overcrowded conditions, even in death. This view of a cemetery outside Japan's ancient former capitol, Kyoto, illustrates plainly that though life may end, overcrowding goes on... and on...
