The population growth will have severe repercussions as deforestation in the Himalayas causing heavy floods and tropical storms.

7. Pakistan

It is reported on Worldometer elaboration that on 5th August 2021 Pakistan’s population has touched the figure of 225,568,591. Population density is 287 per sq. km. 22.8 years is the median age here. Only 35.1% population is located in urban areas.

High fertility rate, low prevalence of contraception, wanting male child, early marriages, lack of women empowerment, illiteracy, and decline in death rate are the major reasons for population explosion here.

Pakistan occupies only 0.59% of space on earth and inhabits 2.83% of the world’s population. Sixty percent of Pakistan’s population is under 30 years of age. Thus, it needs more resources to raise the young population. Social and cultural superstition is a big obstacle in population control here. Also, it has around 2 million refugees. Food security is the biggest challenge for the country today.

6. Nigeria

Nigeria ranks sixth in the population ranking of the world due to high fertility and low mortality rates.

Nigerians believe in extended families due to family labor for farming. The more working members, more are the more security is their reason for large families. Male child preference and illiteracy is the root cause of the steep rise in population.

As of August 6, 2021, the population led 211,702,933 as per the Worldometer elaboration of United Nations data. This figure is a synonym for 2.64% of the world’s population. Population density is 226 Sq. Km.

Several policies have been sketched for population control but they failed because of limited political will and delayed or non-release of funds for it.

5. Brazil

Due to the high immigration rate from European and African nations, the population of Brazil has hiked rapidly. Half of Brazil’s citizens remain under twenty years of age. Although the birthrate has significantly dropped in Brazil, elderly citizens have a high life expectancy.

Currently, Brazil comes at 5th spot among the topmost populous countries with a population of 214,211,100 as per the Worldometer elaboration of data from the UN. Brazilian citizens are 2.73% of the total people in the world. Most of the population resides along the Atlantic coast lying in its eastern part.

51% of the population are female while 49% are male. Sao Paulo is its most expensive city and homes nearly 90% of the population. The population density is very low in Brazil.

4. Indonesia

From the projections of the United Nations, the population of Indonesia is around 276,361,783 in July 2021. Indonesia ranks four among the top 10 most populous countries in 2021. Thus, the 4th place among the top 10 countries with the highest population in the world goes to Indonesia.

Half of its population resides in Java Island. The capital city Jakarta is ranked as the world’s second-most populous urban region. Indonesian marks 3.51% of the world’s population. The sex ratio is 0.994 which is quite low. The concentration of people in certain regions makes it densely populated.

Lack of awareness on family planning norms, underage marriages, lack of education, conservative mentality, poverty, and the high birth rate is the key to population hike here. Besides, unemployment indirectly contributes to population growth where many unemployed youths chose to marry and reproduce. However, the government is zeroing on norms to combat the population graph here.

3. United States of America

The nation contributes to 4.5% of the world’s population, making it the third-most populous nation in the world. Its population is 333,111,358 as per the projections of the latest data from the UN. Due to its high land occupation, the country is not densely populated. The population density is 94 people per sq. miles and urban residents are 82.8%. The growth rate of the population is 0.61%.

High fertility rates and huge immigration are the key factors of the increasing population in the USA. Nearly 10,903 births and 8159 deaths take place per day. New York is the most populated city in the USA.

2. India

India comes at 2nd place among the most populous countries in the world as of 2021. As per the United Nation’s Worldometer elaboration, India has reached 1,394,827,667 in numbers. This amounts to 17.7% of the total world’s population. The population density is 1202 people per mi2.

In the past few decades, a fall in population growth has been seen due to increasing urban migration, elevation in education, and downfall in poverty. The steep rise in population attributes to a huge difference in death and birth rates. Other major reasons are illiteracy, early marriages, poverty, illegal migrations, son preferences, and low awareness rate.

The usual drawbacks of overpopulation are unemployment, manpower utilization, limited infrastructure, limited resource, and unequal income distribution to list a few. 

1. China

China’s population is approximately 18.47% of the total world’s people. As per the Worldometer elaboration data by the United Nations is 1,445,403,092. So, with this data, China remains the most populous country in the world in 2021.

With the rapid industrialization and advance agricultural practices, people here opted for big families. This was simply due to their capability to sustain them. The population density of China is 153 Sq. Km.

Due to the dense population in certain parts of China, there is a fear of land and resources degradation. Better policies, quality education, and urbanization can let China achieve its target of population control. The one-child policy of China ended and since 2015, the population has risen by 0.46%.
