Factors influencing population growth

Explanation: Migration of squirrels can cause decrease in population in an area. Squirrels migrate or move for one place to another which can be as a result of drought, food shortage or overpopulation.

• Light and Nutrition. The more food and water an animal’s population has at its disposal, the more likely it will be bigger in size.
• Habitat and Niche. The type of habitat an animal inhabits will also affect the population’s size.
• Competition and Predation.

What is the most probable reason for the increasing predator population from day 5 to day 7? n a marine ecosystem, algae are able to use sunlight and inorganic materials to make their own food. Clams feed on the algae by filtering them out of the water.

• Economic development.
• Education.
• Quality of children.
• Welfare payments/State pensions.
• Social and cultural factors.
• Availability of family planning.
• Female labour market participation.
• Death rates – Level of medical provision.

After all, population change is determined ultimately by only four factors: birth, death, immigration, and emigration. This apparent simplicity is deceptive. It is easy to underestimate the complexity of biotic and abiotic interactions in the natural world that can influence these four population parameters.

Several factors are responsible for the rapid growth: a drop in mortality rates, a young population, improved standards of living, and attitudes and practices which favor high fertility.

Slower population growth means that women on average are having fewer children, which gives girls and women the opportunity to pursue education and careers and continue a positive cycle of schooling, autonomy and equal status. Slower population growth will also place a higher value on immigration.

And smaller populations also mean less crowding, which can cut commute times, reduce stress, maintain green areas, and improve quality of life, according to Israeli environmentalist Alon Tal.

There are some benefits of overpopulation, more people means more labor force, it can product more things, and more people will buy the products, However, the growth of population should be similar to the food supply, so overpopulation will cause lack of food, and as the rate of growth of population exceeds the rate of …

women also means that families had a better opportunity to change their financial situation. Men were the primary income earners for much of the one child generation, which meant fewer food shortages, less poverty, and better educational options for the next generation.

The three-decade old rule was officially rescinded this week. But its toll will haunt China for years to come. China’s one-child policy was aimed at slashing the nation’s population to boost economic growth. It resulted in millions of forced sterilizations, abortions, infanticide, and marital misery.

The negatives include accelerating population ageing, the skewed sex ratio, and the decline in the working-age population, which would threaten economic growth. Moreover, in 1980 the government had pledged that the one-child policy would last for just one generation, so change was overdue.

The policy has been beneficial in terms of curbing population growth, aiding economic growth, and improving the health and welfare of women and children. On the negative side there are concerns about demographic and sex imbalance and the psychological effects for a generation of only children in the cities.

The one-child policy was a Chinese government policy to control population growth. According to estimates, it prevented between 200 to 400 million births in the country. It was introduced in 1979 and discontinued in 2015, and enforced through a mix of incentives and sanctions.

Wang pointed out that the enforcement of the policy allowed most Chinese families to spend less on children per capita, and that in turn helped with savings, investment and economic growth.

Hence, China’s One Child Policy, which restrains rapid population growth, has been an effective way of reducing the country’s environmental impact. The rapid decrease in energy intensity was the main factor restraining the increase in China’s environmental impact but recently it has also been rising.

China no longer has a “one-child policy,” but it still keeps a lid on births. Beijing on Monday said it would allow all couples to have up to three children, another gradual lifting of its birth restrictions as the number of babies born continues to shrink and the population ages.

The one child policy is associated with significant problems, such as an unbalanced sex ratio, increased crime, and individual dissatisfaction toward the government.

The Chinese government had expected the abolishing of the one-child rule would lead to an increase in births to about 21.9 million births in 2018. The actual number of births was 15.2 million – the lowest birth rate since 1961.

The Chinese government estimated that some 400 million births were prevented by the policy, although some analysts dispute this finding. As sons were generally preferred over daughters, the overall sex ratio in China became skewed toward males. In 2016 there were 33.59 million more men than women.

The one-child policy was a program in China that was implemented nationwide by the Chinese government in 1980 in order to limit most Chinese families to one child each. The policy was enacted to address the growth rate of the country’s population, which the government viewed as being too rapid.

At the national level, a 1% increase of population growth rate would facilitate a 1.7% increase in economic growth rate. However, the one child policy slowed down the population growth, which indirectly lowered the national economic growth.

For example, in 1979, China established a “One-Child Policy” to reduce the rate of population growth. China’s population for 2000 shows a large bulge in the 25-34 age cohorts, which represents the high birth rates over 25 years ago (prior to 1975). This may be an effect of the one-child policy.

The policy affected millions of couples and lasted more than 30 years. According to the World Bank, the fertility rate in China dropped from 2.81 in 1979 to 1.51 in 2000. The reduced fertility rate is likely to have affected the Chinese labor market profoundly.
