The population is a severe topic, its complete information is given in many schools, and ERP for school is used in many schools. Enterprise Resource Planning is a business management software that stores informative data and manages all of them.
Population distribution means how people space over the Earth’s surface; broadly, 90% of the world population lives in about 10% of the total land area.
The Density of Population:
It is defined as the ratio between the number of people to the size of the land. It is usually measured in persons per square kilometer. Factors influencing the distribution of population are mentioned below:
- Geographical factors
- Availability of water landform climate soil
- Economic factors
- Mineral and urbanization
- Social and cultural factors
Political stability, cultural and religious significance, government policies, and incentives
Availability of Water Influences the Distribution of the Population:
Water is the most crucial factor in life, so people prefer to live in areas where freshwater is readily available for day-to-day activities such as agriculture industry and navigation.
Landforms influence the distribution of population.
Before, people lived on flat planes and gentle slope areas because such areas were favorable for the production of crops and for building roads and industries, such as the Ganga plain.
The mountaineers and hilly areas hinder the development of transport networks and hence initially do not favor agriculture and industrial development, so these areas 10 to be the less populated example of the Himalayas.
climate influence the distribution of the population
Extreme and Harsh climates like hot and cold deserts or areas with heavy rainfall have a low population. In contrast, sites with more people have a comfortable environment and minor signal variation.
Soil influence the distribution of the population:
Fertile soils are essential for agriculture, and Elite activities hens’ areas with fertile loom soil have more people living on them as it can support incentive agriculture.
economics factors that influence the distribution of population
Areas with mineral deposits attract industries mining, and industrial activities generate employment, so skilled and semi-skilled workers move to these areas and make them the densely populated example, Katanga Zambia copper belt in Africa.
Cities with better employment opportunities, educational and medical facilities, better means of transport and communication, good civic amenities, and city life attract people to the cities at most minuscule two rulers to urban migration and cities grow in size.
the industrial belt provides job opportunities and attracts a large number of people, including transport operators’ shopkeepers’ bank employees’ doctors’ teachers, and other service providers example, the Kobe Osaka region of Japan
Growth of population:
Change in population in a particular area between two points of time is known as population growth; this change may be positive or negative. It can be expressed in terms of absolute numbers or the percentage of the natural development in any population.
The natural growth of population is the population increase by the difference between birth and death in a particular region between two points of time. The actual growth of population is the national growth of population in-migration -out-migration. Actual growth of population=birth-death+in migration-out migration.
the positive growth rate of the population:
A positive growth rate of the population happens when the birth rate is more than the death rate between two points of time or when people from other countries migrate permanently to a region
the negative growth rate of the population:
If the population decreases between two points in time, it is known as negative population growth. When the birth rate falls below the death rate, or people migrate to other countries.
Components of population change and how science and technology help population growth?
There are three components of population change crude birth rate, crude death rate, and migration. The steam engine replaced human and animal energy and provided mechanist energy of water and wind; this increased agriculture and industrial production. Inoculation against epidemics and other infectious diseases improved medical facilities and sanitation, contributing to a rapid decline in that rate. Does technological advancement achieve so far help reduce the death rate and provide a stage for accelerated population growth? There is member of areas with high population density in the world. Why does this happen?
The areas with a high density of population worldwide have at least one or usually multiple factors favorable for the settlement of population. People found the conducive conditions for living they have been settling there with passage of time and growth of people this area became regions of thick population density. For example, the areas with the availability of good water climate present minerals and other religious or cultural significance resources became regions of the broad population.
Example Ganga Yamuna roads, the Mediterranean region.
Demographic transition and three stages of demographic transition theory:
Demographic transition theory can describe and predict the future population of any area. It tells us that the people of any area change from hybrid and high death to birth and lower that as society progresses from rural agrarian and illiterate to urban industrial and literate.
- The first stage has a high fertility rate and mortality rate because people reproduce more to compensate for death due to epidermis and variable food supply. The population growth is slow, and most people are engaged in agriculture. The last families have an asset life expectancy.
- In the second stage, fertility remains high. Still, it is declared that this is accompanied by reduced mortality rate improvement in sanitation and health conditions leads to a decline in mortality rate. Because of this gap, the net addition to the population is high.
- In the third stage, fertility and mortality decline considerably; the population is stable or grows slowly. The people became urbanized by the trade, had height technical know-how, and deliberately came to the family size.
Students of every school have to read this chapter, and sometimes it is difficult for them to cover the whole chapter, so students can take the help of online studies to read it well online. They will get complete information about it in less time, and they can also use the school ERP software.
