...has caused appalling human rights abuses in China, including forcible abortions and sterilizations. Since the policy went into effect, China has had a significant gender imbalance, an abnormal sex ratio. China’s rapidly aging population—combined with lower fertility rates—is expected to present significant social and economic challenges. It also brings other problems, for example, the "four-two-one" problem and unequal enforcement. Argument 0: One-child policy benefits exaggerated The government states that 400 million births were prevented by the one-child policy until 2011; this claim is disputed as official propaganda by Wang Feng, director of the Brookings-Tsinghua Center for Public Policy, and Cai Yong from the Carolina Population Center at University of North Carolina Chapel Hill, who put the number of prevented births from 1979 to 2009 at around 100 or 200 million. Argument 1: Low fertility rate can’t maintain the sustainable development of society. According to the sixth census population, currently one couple only has 1.2 children on average. In cities, the number is less than 0.9. Even for people from countryside, it is 1.5. Under ideal mathematic model, the fertility rate should be 2.1. The 1.2 fertility rate means the number of population decrease 40% every generation. The low fertility rate can’t maintain the sustainable development of society. According to the experience in other developed countries, it is almost impossible that the fertility rate will increase...

...Population explosion is the most serious problem facing our country today. With 16 per cent of the world’s population, India is toady the second largest populations’ country in the world. As on March 1.1991, when the last census was conducted, the country’s population stood at 846.30 million, with 439.23 males and 407.07 females. The country’s population is currently estimated at about 950 millions. The population growth has been extremely rapid in the last 50 years. The phenomenal growth is now more appropriately termed as “population explosion”. The phenomenal growth rate in population is largely because of the industrial and technological revolutions that had taken place in the recent times. The new technologies have not only brought down the death rate because of the vastly improved Medicare resulting in increased life expectancies, but had also facilitated increased food production to take care of food needs of the increasing population. Though population explosion is a major problem being faced by several other countries too, with the world population estimated to reach 7 billion by the beginning of the 21st century, the problem is much more severe in India because of the increasing pressure on the limited resources of the country. With the growth of food grains not keeping pace with the increase in population during some years because of the unfavourable weather conditions, the specter of hunger hunts millions of households in the country. Even when the country...

...all link hands we could wrap around the world 175 times. We could even reach to the moon and back eighteen times. The number of people on our planet is increasing all the time. MATTHEW HOLBROOK, REPORTER: Imagine this grain of rice is one new person added to the planet. And each day our world's population grows by this much. That's 200,000 extra people in a single day. It's a huge number, but it's only in recent history that our population's really taken off. At first, the world grew really slowly. Scientists reckon it took tens of thousands of years to reach the million mark. Over time, things started to speed up. So in the past few years you can see there's been huge growth in a short space of time. That growth is likely to continue towards ten billion by the end of the century. So why is our population getting so high? Well, we have better healthcare and hygiene now than in the past. We've learnt to deal with some dangerous diseases, and more of us are living longer. Australia is growing, too. In the last 50 years our population has more than doubled to twenty two million people. So what's it likely to mean to you if our population keeps getting a lot bigger? By 2050, our population is expected to grow to thirty six million people. REPORTER: It might sound like a tight squeeze and you could imagine us being crammed together like sardines in a can. But in a country as big as Australia, space isn't going to be the...

...ESSON 2: POPULATION AND ECONOMIC DEVELOPMENT UNIT I: POPULATION  LESSON 2  ‘POPULATION AND ECONOMIC DEVELOPMENT’ - Dr. Anupama Rajput Studying this chapter should enable you to understand:  * Theory of Demographic Transition * Demographic Profile of India * Population Growth and Economic Development * Population Policy of India Introduction: The size and composition of a country’s population can exert a powerful influence on a country’s development. The population size, composition, and distribution influence the range of industries a country can support and the pool of talent that are available in the country.In size of population, India is the second largest country in the world after China, constitutes 2.4 per cent of the world’s land area and supports 16.25 per cent of the world’s population. The population growth in India has proved to be more an obstacle to its development efforts rather than a contributory factor in economic growth.  Theory of Demographic Transition: The theory of demographic transition states the impact of economic development on the population growth of a country. The earliest systematic discussion on the theory of population growth is provided by Malthus in 1798. Malthus stated that population growth always exceeds the growth of means of subsistence and warned that the uncontrolled population had to be corrected by nature which would be very painful. Economists however, argued that the population growth is a transitory phenomenon that...

Population Geography

...Population geography is a large branch of geography that contains several different topics related to the world's population. The first of these is population distribution, which is described as the study of where people live. World population is uneven as some places are considered rural and are sparsely populated, while others are more urban and are densely populated. Population geographers interested in population distribution often study past distributions of people to understand how and why specific areas have grown into large urban centers today. Usually, sparsely populated areas are harsh places to live such as Canada's northern territories, while densely populated areas like Europe or the coastal United States are more hospitable. Closely related to population distribution is population density - another topic in population geography. Population density studies the average number of people in an area by dividing the number of people present by total area. Usually these numbers are given as persons per square kilometer or mile. There are several factors which affect population density and these are often subjects of population geographers' study as well. Such factors can relate to the physical environment like climate and topography or be related to the social, economic and political environments of an area. For example, areas with harsh climates like California's Death Valley region are sparsely populated. By contrast, Tokyo and Singapore are densely populated because...

Aging Population

...The Aging Population The aging population is living longer than ever before and according to statistics this longevity and aging will continue to grow. The importance of providing the Fifty million aging Baby Boomers are sparking demand for products and environments that accommodate their changing physical and sensory capabilities. Today, one out of every 9 Americans is "old"—another former youth turns 50 every 8 seconds. Those age 65 and older now exceed 35 million, a number poised to explode. January 2011 ushered in the first of approximately 77 million Baby Boomers, born from 1946 through 1964 and are surging toward the gates of retirement (transgenerational). This growth will steadily increase and the population must be prepared to accommodate the aging population. According to the Bureau of Vital Statistics the aging population is the fastest growing population and will continue to increase. This dramatic growth in numbers and proportions, increased life expectancies, and energetic life styles, now enables us to live 20 to 25% of our lives in active retirement. Moreover, today's physically and intellectually active younger generations predict that tomorrow's elderly population will be better educated, healthier, culturally literate and, as individuals, more discerning consumers.

Populations Pyramid

...19 February 2014 “Population Pyramids Assignment” 1) Brazil Brazil’s population is growing slowly since the lower end of the pyramid is wider than the top, but the lowest portion of the pyramid is not as wide as the middle. This means that birth rates are higher than death rates, but does not mean that the Total Fertility Rate (TFR) is high. It seems as though Brazil had its highest rate of growth between 1980 and 2004. 2) Swaziland Swaziland’s population is growing rapidly since the lower end of the pyramid is much wider than the top. Every age group that decreases in age accounts for a higher percentage of the population. This means that the birth rate is much higher than the death rate, and also that the TFR is high. 3) Estonia Estonia’s population is decreasing slowly. This is because the population pyramid is mostly top-heavy, and the proportion of the population that is in the top half is not significantly greater than the proportion of the population that is in the bottom half. It also seems as though there are more women in Estonia than males that live longer. There is also an echo boom in this pyramid for people between the ages of 50 and 64 and their children between the ages of 25 and 34. 4) Vietnam Vietnam’s population is increasing slowly because their population pyramid has a narrowing base. This means that birth rates are falling and momentum for future population growth is not nearly as high as it was. It also seems that men and women are likely to live...

...government policies have helped to ease the aging process.” Discuss this statement in relation to your particular field of study or interest (e.g. economics, science, medicine, social policy, architecture, psychology, technological inventions). “Population ageing is both a triumph and a challenge” (Lim, 2008). With the advances in economics and medical development as well as better health systems, Singaporeans now are having longer life expectancy than they used to have in the past. Current research has shown that Singapore is one of the fastest ageing populations among Asia. However, the drop in birth rates over the past years has resulted in a smaller ratio of younger Singaporeans. Chan (2000) states that as there are fewer people to take care of the elderly, taking care of the elderly will rest on the government’s shoulder and this will has implications on the economy, financial security, living arrangement as well as health care system within the country (Chan, 2000). With researches done on the ageing population and the social policies, in terms of economy, living arrangement and health care system, implemented, these can help to ease the ageing process. In order to maintain financial security so that the problem of ageing population will not affect the economy, the government has come out with a few policies. As Singaporeans now live longer, they will thus have to work longer. The government promotes lifelong employability to enhance elderly’s employability. By extending the...

...TaVonna Daniel 4/30/15 Human Population growth, Natural Selection, and the tragedy of the commons Human Population simply means a number of people, living in a particular area country or region at a particular time. The current human population growth is something unknown in the history of the world. If we look back to the history of human population growth Birth rate expressed as number of births per one thousand per year currently also 13 in the U.S. but death rate expressed as the number of deaths per year are currently 8 in the U.S. So the rate of natural increase is 5 per thousand. Although the value is affected by both birth rate and death rate, the recent history of the human population has been affected more by declines in death rates than by in birth rates. The introduction of public health measures, such as better nutrition greater access to medical care improved sanitation more widespread immunization. The rapid growth of population is one of the greatest obstacles in the progress of developing countries. If the population grows fast, poverty cannot be eradicated. Progress made in the fields of agriculture, industry and technology fails to cope with the needs of a rapidly growing population and leads to poverty and unemployment. A high rate of birth and a decline in death rates have resulted in population explosions, especially in underdeveloped countries. The Census Report of 2001 states that while in Europe, the population growth rate is 0.3 per cent, in India...

...their effect on the Environment The effect of overpopulation and over consumption on the environment has had a massive negative effect. Overpopulation is an undesirable condition where the number of existing human population exceeds the carrying capacity of Earth. We are now adding one billion people to the planet every 12 years. That's about 220,000 per day. (Howmany?.org) This makes overpopulation a big threat to our environment but the bigger issue is that we are not using our resources efficiently to solve the problem. The problem includes shortages of all our resources, war and social conflict, limits on personal freedom, overcrowding in large cities and the health and survival of other species. In the last fifty years, there have been a vast number of people and organizations rising up and speaking against this problem, searching for a solution to this detrimental issue. Howmany?.org is just one of many organizations that are empowering people to find the best population size for Earth. They do this through outreach and advocacy programs that are created to add population into conversations and get people thinking. While overpopulation is not the only cause of environmental problems, it is a root cause that people should be aware of. Growth in population, affluence, and technology are jointly responsible for environmental problems concerning overconsumption. We use technology to produce and gather most of our resources. While technology helps make life easier for...

Elderly Population

...Vulnerable Population: Elderly population NUR/440 July 11, 2011 Anavictoria Fortaleza Vulnerable Population and Self-Awareness Paper The Elderly Population According to Chesnay (2008) “vulnerable populations are those with greater than average risk of developing health problems by virtue of their marginalized sociocultural status, their limited access to economic resources or personal characteristics such as gender or age. Anyone can be vulnerable at any given point in time as a result of life circumstances or response to illness or events” (p 3-4). For the last few decades, society and government have put a great deal of concern and interest on the aging population. The number of elderly population in the United States is rapidly increasing. The US population under the age of 65 tripled during the 20th century. This number is to double by the middle of next century. Over 70 million American citizens will be considered elderly by 2030, or about 20% of the population will be senior citizen (Walsh, 2009). The growing numbers are attributed to aging “Baby Boomers” and increasing life expectancies. Disability and disease are more common in elderly population such as hip fractures, parkinson’s disease, malnutrition, cardivovascular disease and malignant cancer. More than 70% of the elderly population has been diagnosed with a chronic disease (Pishchita, 2007). According to CDC, arthritis is the leading cause of disability among individuals over 65 years of age and 47% of...
