Population Growth And Distribution

The rise in population has been steadily rapid since 1650.

Explanation

The world population has been rapidly rising since 1650. It approximately reached 500 million by the 1700s. Because of the constant technical advancement in the field of medical sciences and other allied facilities, the world population has been ever increasing since then. Because of the fall in death rates and the increasing birth rates, the population growth has shown only increasing trends.

The birth rate is the number of live birth in a year for every 1000 women in an area.

Explanation

The birth rate is the total number of live births in the country in a particular period of time for every 1000 women. It determines the increase or decrease in population in the country. Many important factors determine the birth rate in a particular area. In most developed counties, the birth rate would be less compared to the underdeveloped and developing economies.

The world Population reached 6 billion in the year 1999.

Because of the fall in death rates and the increasing birth rates, the population growth has shown only increasing trends. In 1999, it reached 6 billion and by 2011, it has crossed 7 billion.

Natural factors and human factors affect the distribution of people across the world.

Explanation

The concentration of settlement depends upon many important factors like the availability of water, natural resources, climatic conditions and the type of region. The nature of the region and the climatic conditions, the availability of clean water also influence the concentration of settlement, along with other human factors and availability of services.

Population density is calculated by dividing the number of people in a country by the area of that country.

Explanation

Population density is the measurement of population per unit area or per square kilometre. National Capital Region, Delhi is the most densely populated area in the country with a density of 11320. Among states, Bihar is the densely populated state in India with a density of 1106. This data is according to the 2011 census.

When birthrates are high and death rates are low the population of an area will increase.

Explanation

The population growth is determined by the differences in birth rate and death rate. The birth rate is the number of live births in a year for every 1000 women in the total population. The death rate is the number of deaths per 1000 live births. Both the factors determine the increase or decrease in population in the country. When the country experiences high birth rates and low death rates, the population growth rate will be high.

Population distribution is the spread of people on the land surface. The most populated countries in the world are China and India. China is the most populous country while India is the second most populous country. But the land area they occupy is less than 10%. Thus, about 90% of people live on 10% of the land area.

Population density is the measurement of population per unit area or per square kilometre. It is calculated by dividing the number of people in a country by the area of that country. Bangladesh that constitutes 2.4% of the world population has the highest population density of 1069 per square kilometre.

Population density is the measurement of population per unit area or per square kilometre. The climate of the area also determines the density of human settlement. Population and settlements will be much lesser in deserts and arid lands with less rainfall. The population will be higher in the coastal areas and the plains even if the climate is hot and humid because of adequate rainfall.

Population density is the measurement of population per unit area or per square kilometre. The stability of the government and government policies determine the population density of any country. Countries with stable governments, positive government policies and less political problems and violence will have high population density.

1. The world population has been rapidly rising since 1650. It approximately reached 500 million by the 1700s. Because of the constant technical advancement in the field of medical sciences and other allied facilities, the world population has been ever increasing since then. Because of the fall in death rates and the increasing birth rates, the population growth has shown only increasing trends. In 1804, the world population reached 1 billion.

2. Population density is the measurement of population per unit area or per square kilometre. It is calculated by dividing the number of people in a country by the area of that country. Monaco has a very high population density because of its small size. It has a population density of 16779 people per square kilometre as the size of the country is just 1.95 square kilometre.

3. The population growth is determined by the differences in birth rate and death rate. The birth rate is the number of live births in a year for every 1000 women in the total population. The death rate is the number of deaths per 1000 live births. Both the factors determine the increase or decrease in population in the country. When the country experiences low birth rates and high death rates, the population growth rate will be low.

4. Population density is the measurement of population per unit area or per square kilometre. It is calculated by dividing the number of people in a country by the area of that country. Australia is the smallest continent in the world. It has a total of 0.3% of the world population. It has the least population density of 6.4 people per square kilometre.

5. Population density is the measurement of population per unit area or per square kilometre. It is calculated by dividing the number of people in a country by the area of that country. Germany has the least population density. It has a population density of 227 people per square kilometre. It is the 17^th most populous country in the world.

(a) The birth rate is the total number of live births in the country in a particular period of time for every 1000 women. It determines the increase or decrease in population in the country. Many important factors determine the birth rate in a particular area. In most developed countries, the birth rate would be less compared to the underdeveloped and developing economies. When the birth rate is high, the population growth rate will also tend to be high.

(b) The death rate is the number of deaths per 1000 live births. It determines the increase or decrease in population in the country. Many important factors determine the death rate in a particular area. In most developed counties, the death rate would be less compared to the underdeveloped and developing economies because of the improvement in medical science and other facilities. When the death rate is low, the population growth rate will also tend to be high.

(c) Population density is the measurement of population per unit area or per square kilometre is known as population density. National Capital Region, Delhi is the most densely populated area in the country with a density of 11320. Among states, Bihar is the densely populated state in India with a density of 1106. This data is according to the 2011 census. Availability of water resources, climate, topography, economic, social and other political factors determine the population density in the country.

Population density is the measurement of population per unit area or per square kilometre. The climate of the area also determines the density of human settlement. Population and settlements will be much lesser in deserts and arid lands with less rainfall. The population will be higher in the coastal areas and the plains even if the climate is hot and humid because of adequate rainfall. The existence of lakes and rivers is an important feature influencing the growth of settlements. Only these regions will permit cultivation and allied activities like dairying. The landscape is an important aspect influencing the growth of human settlements. Flat, plain and fertile lands will be more densely populated as compared to hilly and rugged areas. The transportation and other facilities will be more developed in the plains leading to a higher concentration of population.

Regions rich in fertile soil and other natural resources will be densely populated than others. The rich natural resources will provide more opportunities for the people thus improving their quality of life. Areas with favourable climate tend to be densely populated as there are enough rain and heat to grow crops like Ganges plains and India. But on the other hand areas with extreme climates are sparsely populated lie the hot deserts and cold deserts.

the world's population growth has been always growing at a rapid speed. It reached 500 million by 1650 and has been at an increasing rate. It reached 1 billion in 1804. The second billion was added after 123 years in 1927. Since 1950 the rise in the population has shown growth. In 2011 records it is found that the world population has reached around 7 billion. The economic growth with industrial and agricultural growth and developments has increased the rate of population growth.

Different human factors that affect the population growth are:

The life of people in the Himalayas:

Life of people in Thar desert

Major reasons behind low population density in these areas are:

These places are hilly, dry and rocky in nature. They have shallow fertile land which makes the climate and natural aspect of life harder than the one in plains. That also makes unfavourable conditions of life leading to low population density.

This figure shows the density of the population across the world.

Areas with dark brown are very dense population. Areas with red are high dens populated. light pink shows which have a less dense population. And the rest is the least densely populated.

Favourable climate, economic and social factors and natural sources, political factors and the distance from the sea are here to determine the population of any country.
