FACTORS IN POPULATION GROWTH The key factors in population change are natural increase

Producing and acquiring all these manmade products is termed as capital formation. They feed on plants and compete with crops for nutrients, water and space. The geographic factors include climate, soil factors, natural resources and transport facilities. There are few countries which have maintained their development by immigration. The population growth rate can result in either a positive or negative rate depending on the factors.

What are factors that control population growth? How do they affect it?

factors affecting population growth

All populations on Earth have limits to their growth. When someone moves to a country from another place, it is known as immigration. Biotic factors in a community are essential in creating a balance of life in the ecosystem. This accelerating pattern of increasing population size is called exponential growth. An individual deer's chance of dying doesn't depend at all on how many other deer are around.

Environmental Limits to Population Growth

factors affecting population growth

An important characteristic of economic growth is that it is never uniform or same in all sectors of an economy For example, in a particular year, the telecommunication sector of a country has marked a significant contribution in economic growth whereas the mining sector has not performed well as far as the economic growth of the country- is concerned. This is a factor that supports or increases the growth of wolf population. There are three different sections to an S-shaped curve. Examples in wild populations include sheep and harbor seals b. On the other hand, if this ratio is below 2, the population of the region may be destined for a decline.

Factors Affecting Population

Examples of logistic growth Yeast, a microscopic fungus used to make bread and alcoholic beverages, exhibits the classical S-shaped curve when grown in a test tube a. It killed 20 to 40 million people across the globe. Therefore, the human resources of a country should be adequate in number with required skills and abilities, so that economic growth can be achieved. Since a majority of the population is uneducated, they are unable to understand the need for family planning. In addition, it may increase infant mortality if clean water is unavailable resulting in a significantly higher birth rate as people have more children in order to ensure some survive. However, the campaign to reduce the number of children per family is stopped due to many negative outcomes that could arise because of that.

What Are the Factors Responsible for Population Growth?

The city you move to may begin to experience very fast growth if large amounts of people are moving there. Different populations have different ability to tolerate changes in weather, physico-chemical and biotic factors. It affects populations in many parts of the globe. In cold countries, death rate may also be high due to the effects of the cold and a lack of supplies and easy access to them. Over time, the human population has increased, which results in a positive population growth rate, which is the rate at which the population changes in size.

They will continue the attempt until the desired result. A graph of this equation yields an S-shaped curve; it is a more-realistic model of population growth than exponential growth. This was a large number compared to the First World War. Since that time, the population has more than doubled and continues to increase. Given above are the main factors that affect population growth.

Population regulation & density dependent factors

factors affecting population growth

As an example, let's look at a population of lemmings found in Greenland. The best examples of such economies are developed countries, such as United States, United Kingdom, Germany, and France. But it is not the only criteria which define the rate of growth of population. It affects the population size of both the host and destination countries. The more people there are in your city, the more these resources will become limited.

We offer help through guidelines on how to write different academic papers, samples of academic papers posted online or model papers customized to your specifications. Labour means efforts of human beings that is input into the production. Density-independent regulation and interaction with density-dependent factors Many factors, typically physical or chemical in nature abiotic , influence the mortality of a population regardless of its density. In logistic growth, population expansion decreases as resources become scarce, leveling off when the carrying capacity of the environment is reached, resulting in an S-shaped curve. The natality is decreased slightly and there has been increase in the population in our country due to the better health care, education, food supply and sanitation.

We are a flexible writing service provider. Countries who are in the early stages of economic development tend to have higher rates of population growth. The quality and quantity of available human resource can directly affect the growth of an economy. Factors that impact the population more as the population increases are density-dependent factors, while density-independent factors are factors that affect the population the same regardless of size. The other areas are less dense and are less populated. They show a direct relationship.
