Population Trend: Demographic Transition Model

The European demography experienced its most significant transformation between the 18th and 19th century which can be illustrated using the Demographic Transition Model (DTM) . This model correlates to a country’s development: as it moves from a pre-industrialised to an industrialised system, the population growth rate moves from high birth and mortality rates to low birth and mortality rates. 1700 to 1900 Europe saw three phases of this model – the pre-industrialized phase saw high birth rates and high mortality rates due to high fertility and spread of epidemics. The first stage of the DTM can further be elucidated by the Malthusian theory. According to the Malthusian theory, population increased geometrically while food production grew

Modern medical advances have lengthened the human life span, such that it is now longer than it has been at any point in human history. These advances happened alongside the

Imagine your are an elderly couple and has a son/daughter that passed away due to illness,or in a disaster and with the One child policy what would you do? Well the One Child Policy was made to prevent more increase in population the policy was made in 1970 by the chinese governors to help balance the population. The One Child Policy was a bad idea for China for these three reasons Challenge for women,Neglection of the elder,and The policy was just not necessary. One reason that one child policy was a bad idea because it was challenging for women.[Anthropologist Vanessa] Fang argues that this generation of urban singleton girls have been empowered to challenge some of the gender norms that have been long dominated by the chinese life [Document D].Nonetheless an,April [2009] study published in British Medical Journal found china still has 32 million more boys than girls under the age 20.[Document E].

In the 21st century, population studies are very significant in looking at characteristics of a country, habitat, community and other environments. For example, in the human population, people are interested in a country’s population growth/decay, as the production of goods, social reforms/support or other needs of the people can be suggested. If a population is decreasing, there can be efforts made to improve medications and social support to increase the population and decrease the death rates. But do we actually know how population is modeled and how accurate these models are? This exploration aims at comparing logistic and exponential growth models, the two main models used for population growth, and to determine the extent of how realistic

What China was trying to achieve with the One Child Policy was fix a problem they had caused in the first place, when, Mao Zedong, encouraged having more children to have more future workers, and discouraged the use of birth controls (Intro). The One Child Policy came into place in 1980, effected the ethnicity of Han Chinese and was definitely not one of China’s best ideas. It caused many hardships for the citizens of China. The policy was unnecessary for many of three reasons: the fertility rate was already dropping, there is a huge gender and age imbalance, as well as it is to blame for some of the youth’s social issues. From 1970 to 1979 there was a big reduction in fertility rates in China from 5.8 to 2.7, which was prior to the One

Mao Zedong, one of the most influential leaders in Chinese history, once said that, “Of all the things in the world, people are the most precious.” One of the biggest problems that he faced was the growing population of China. At first, he discouraged birth control, but when the growth rate was growing astronomically, Mao introduced “Late, Long and Few.” When even this was not slowing down the population growth, China implemented a one-child policy. It allowed for the Chinese population to have one child, and was far more harmful than beneficial to China.

Late Adulthood Many people in the United States and other industrialized countries are living longer. The life expectancy at birth now is 81 years old. Although this is an important achievement, it is important for social workers to understand the affects that increase longevity have on the individual, family life and social work practice.

Presently, Nicaragua is in stage three of the demographic transition model. There is a declining death rate, rapidly declining birth rate, and the natural increase rate is moderating. In this stage people are starting to have fewer children because education levels are increasing and contraception is being used more than ever before. The total fertility rate dropped from about 6 children per woman in 1980 to right around replacement level today. The population pyramid of Nicaragua in 2015 shows that the cohorts for ages 0-4 and 5-9 are not much larger than the 10-14 and 15-19 age groups as they would be if the country were in an earlier stage of the demographic transition. The overall shape of the pyramid is in the process of changing from

Using the formula Future value = Present value * exp(rt) I can calculate the future value for the population of the state Georgia. 27.821 million= 10.235 million * exp (0.1*10) is the formula to calculate the future value of Georgia using a rate of growth of 10% and a time of 10 years. 55.643 million= 10.235 million * exp (0.1*20) is the value if the time changed to 20 years. 83.464 million= 10.235 million * exp (0.1*30) is the future value of population at 30 years.

It is “the average number of years a population of a certain age would be expected to live, given a set of age-specific death rates in a given year (Health People.gov).” Within different ethnic groups, “women have a higher life expectancy than men.” Also, life expectancy “provides global information about disparities (Kominski, G. (2014). ” There are gaps between men and women, and between blacks and whites.

The question is, is this a good or bad policy that was placed upon China. China’s policy was a good idea because the children are the center of attention, it eases the pressure on the environment, and the children get a better education. The children in China are the center of attention in their family. “A.J. Song, 23, is the only child in his family…”

Population size may vary as individuals are born or immigrate and other may die or emigrate. One model of population growth is the exponential Population Growth; which is the accelerating increase that occurs when growth is unlimited. It predicts that the larger the population is, the faster it grows. This growth model is normally for short lived organisms due to the introduction of a new or underexploited environment. Next, there is the Logistic Population Growth.

The population law in China is a law invented in the late 1970s by the government in china. To begin with there was only a one child policy where a soon to be mother could only have one baby. If the mother were to be pregnant with twins or triplets they would be aborted immediately. A couple of years later announced that if you were the only sibling in your family you were able to have two children. This law has created less population decreasing traffic on roads having plenty of space and homes for families.
