The World Population Density Distribution & Growth Test - 1

Geographical factors play a crucial role in influencing the distribution of the population, and among the options provided, climate is a significant geographical factor that affects population distribution.
Climate: The climate of a region, including factors such as temperature, precipitation, and humidity, directly impacts the suitability of an area for human habitation.

• People are more likely to settle in areas with a climate that is conducive to their lifestyle and livelihoods.
• For example, regions with moderate temperatures, ample rainfall, and fertile soil are often more attractive for settlement.

Natural Growth of Population: This is the population increased by the difference between births and deaths in a particular region between two points of time. 

Natural Growth  =  Births  –  Deaths 

Actual Growth of Population: This is Births – Deaths + In Migration – Out Migration

The crude birth rate (CBR) is equal to the number of live births (​Bi) in a year divided by the total midyear population (​P​), with the ratio multiplied by 1,000 to arrive at the number of births per 1,000 people.

Region-wise Density of Population(2021)

As seen from the above table Asia has the highest population density in the world. Hence, option (C) is correct.

Positive Growth of Population: This 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.

Immigrants: Migrants who move into a new place are called Immigrants. 

Emigrants: Migrants who move out of a place are called Emigrants.

NRI: A non-residential Indian is a person who stays in India for less than 182 days during the period of the foreseeing financial year. An NRI can also be a person who has gone out of the nation for employment is called an NRI. A person staying abroad for business-related purposes is also called an NRI.

Migrant - A person, whose last usual place of residence was different from the present place of enumeration on the date of inquiry has been considered a migrant.

Population flow from rural to urban areas is caused by many factors, like:

• high demand for labor in urban areas
• low job opportunities in rural areas and
• an unbalanced pattern of development between urban and rural areas.

Negative Growth of Population: If the population decreases between two points of time it is known as negative growth of population. It occurs when the birth rate falls below the death rate or people migrate to other countries.

The first stage has high fertility and high mortality because people reproduce more to compensate for the deaths due to epidemics and variable food supply. The population growth is slow and most of the people are engaged in agriculture where large families are an asset. Life expectancy is low, people are mostly illiterate and have low levels of technology. Two hundred years ago all the countries of the world were in this stage. Hence population growth is low in the first stage of demographic transition. So, option (C) is correct. 

The human population increased more than ten times during the past 500 years. It took 12 years for the population to rise from 5 billion to 6 billion.

Africa has the highest rate of population growth among major areas. The population of sub-Saharan Africa is projected to double by 2050.
