Is Cambodia An Exponential Rate?

However the Demographic Transition model also has its weaknesses some weakness would include the fact that the demographic transition model does not include the role of the government, some governments may put antenatal and prenatal operations in place to encourage the decrease or to increase the birth rate within these countries, therefore countries like China that are antenatal and have the one child policy put in place and countries like the UK which are prenatal and offer child benefits may show fluctuation of the birth rate in stages it should be decreasing or increasing in. Further more In stage four, the UK experienced a post-war baby boom where the birth rate should be steadily decreasing – this shows that the demographic transition model does not include the impacts of wars, natural hazards or migration either.

During the cold war era the life expectancy grew by about 15 years, however in the 1980’s the world saw a decline in life expectancy especially in the USSR falling from 70 years down to 53 years old(C&C 1040). Along with this came an uncertainty for population growth in developed and underdeveloped countries. For example, in China Emperor Deng established a one child policy, in Iran and other Islam dominate countries governments were urging families to space out their conceptions(C&C 1041).

Major progress has been made in curbing population growth. The United Nations Population facts August 2010 states that there has been substantial declines in fertility, total fertility in the rest of the developing world(excluding the least developed countries) declined by about 50 per cent between 1970-1975 and 2005-2010: from 5.0 to 2.5 children per woman. Additionally fertility in the least developed countries dropped by 34 per cent since 1970-1975, from 6.7 to 4.4 children per woman. Bangladesh is exceptional with a reduction of over 60 per cent, from 6.9 children per woman in 1970-1975 to an estimated 2.4 in 2005-2010.

Some demographers believe that the demographic transition will happen to countries everywhere. With urbanization and modernization, they claim rates of natural increase will naturally fall. This is needed most, of course, in much of Asia, Africa, and Latin America where there is great poverty and rapid population growth. Most of the developed world has gone through the transition, and population in the wealthier countries is nearly stable. Detractors of this argument point out that those poorer countries today are very different from the wealthy ones during their early stages of economic growth. They also say the political and economic environment today also work to the disadvantage of the poor

The fertility rate of a country measures the average number of children capable of being born per woman. The rate gives an idea of the future growing or declining population trend. For Liberia the number stands at 4.7 children born per woman. The number is an indication that the population is growing and increasingly becoming younger. As stated earlier, people under the age of 14 comprises over 40% of the total population, which coincides with the younger growing trend predicted by the fertility

One graph is showing US birth rates, by the mothers age during the years 1990-2009. This graph shows that the largest growing age of a mother is 40-44 years. In 1990 it was about 5.2 thousand and in 2009 it shows it has grown to approximately 10 thousand women. Women in the age ranges of 25-29 years, 20-24 years, and 30-34 years have remained consistent during the 10 year period.

In the 1900's the U.S. population growth was increasing rapidly. The diagram shows that there was an age structure of much more younger aged people than older aged people which indicated the population would grow more quickly. In the 2000's the population age structure is becoming more populated with older ages.The population has some small differences between the older generations being slightly higher in numbers than the younger generations, so the growth rate is declining slightly. In 2050, it is projecting the age structure to be very evenly distributed between the older and younger generations which will stabilize the population growth rate to largely remain the same. It shows total populations of both the younger and older generations

In 1950, the average number of children per woman was around 5 and in 2010 that number decreased by 50 percent to 2.5. The major contributor to this dramatic change was advancements in medicine (i.e. birth control). In 1950 the life expectancy of a child was forty-seven and in 2010 it went to seventy. One of the major contributors to this shift was lifestyle changes to healthier living (exercise, diet and less smoking) and advancements in medicine. With aging societies, there comes some potential negative implications to international stability and US national security.

At a glance, you would see the Philippines growing and the city in Arizona’s funnel shape as dying out for lack of any births. For those who know that Sun City only allowed people who were over 65 (unless caring for an elderly relative) to live there in 2012, it would show a thriving community. The comparison of births and old age would mean more money available for care of the elderly instead of more money needed for education. The one feature that is the same in both places is that women outlive men. The Arizona pyramid could also tell medical staff and caretakers that there would likely be more jobs available for them

East Asia had several problems, such as poverty and rapid population growth, during 1950-1960. Their economy was pre-industrial which many people worked on farms. The pre-industrial society consists of several characteristics, such as high birth rate and high death rate. Many young women in Asia (excluding Japan at that time) produced six births each over their reproductive span, leading a rapid population growth. However, East Asia starts to believe population growth is a threat to developmental goals.

Demography is the study of the components of population variation and change. Death rate and birth rate are two determinants of population change. Theory of Demographic Transition is comparatively recent theory that has been accepted by several scholars throughout the world. This theory embraces the observation that all countries in the world go through different stages in the growth of population. A nation's economy and level of development is directly related to that nation's birth and death rates. Population history can be divided into different stages. Some of the scholars have divided it into three and some scholars have divided it into five stages. These stages or classifications demonstrate a

From the 3.68 billion people that will be added to the world population between 1995 and 2050, Asia will contribute some 2 billion. This enormous increase is due to the already massive size of the population. Most of this growth will occur in the next three decades. Between 1995 and 2025 Asia 's population will grow by 1.35 billion - between 2025 and 2050 the increase is projected to be just 658 million. China is the world 's largest population, estimated to be around 1.24 billion in 1998. It grows at a rate of 1.3% per year or 44,100 people a day. There are now more people living in China than whole world 150 years ago. The population broke the billion mark in the 1982 census, the results of which provided the justification for the strict one-child policy which effectively curbed rapid population growth. In the 1990 census, China counted 1.133 billion people, over the next decades the world population will inevitably age. This is an unavoidable consequence of large birth cohorts during the 1950s and 1960s and the rapid fertility decline since the 1970s. In 2025 the "baby boomers" of the 1950s and 60s will be between 65 and 75 years of age. These large aging cohorts are followed by the relatively small "baby bust" generations of the worldwide fertility decline. In 1950 there were only 131 million people of age 65 and older; in 1995 their number had almost tripled and was estimated at 371 million. Between now and 2025 the number will more than double again; and by 2050 we

Analyzing countries through data accumulations is a popular way to make informed decisions on the behalf of the inhabitants and to understand the demographic situations of those areas. Population Pyramids are one of the several types of methods utilized to observe conditions in a clear, efficient fashion. These graphs provide accurate information for the purpose of predicting future issues, making reasonable choices, and can express implications to birth rates, death rates, and other important ideas concerning the demographics.

Argentina’s population is made up of mainly urban and rural populations with a total approximate population of 43,886,748 people. The people of the country are not equally distributed throughout the country. Sixty percent of the population lives in the Pampa Region, with a majority of that population living in the Buenos Aires Provence. The rural citizens make up about eight percent of the Argentine population, and its rate is declining as more of its people go to the city. According to the United States Central Intelligence Agency, while the population is growing, it is doing so at a slower rate due to its declining birth rate. Though while the age demographic of people under the age of fifteen is shrinking, with a median age of 31.5 years old, the 15-24 age group is the largest the country has had in its history and bolsters the working age group. Because of such a robust working age group, the country is expected to have an economic boost. Along with a rather large working age group, Argentina also has a growing aging population that is projected to make 23.4 percent of the population by 2050. The overall population picture of the country looks promising with its large working age group. Though we must take into account both the declining birth rate and growing aging population.

* According to the pyramid of age (exhibit n°1) n there are no big age disparities among the population but we can observe the low birth rate.
