Changes of the top 20 most populated countries in the world based on region 2020

Asia remains the region with the highest population, including the top 2 most populated countries – China and India, as well as the highest number of countries in the top 20 list. The three new members on the list are Thailand, Iran, and the Philippines.

Africa region is catching up with the 3 new members in the top 20 list, which are Ethiopia, Egypt, and DR Congo. These 3 countries are notable with their high yearly increments in the country population.

Europe region is the worst performer in population growth, losing 6 countries in the top 20 rankings.

Here’s the world population share by each region:

Region population share in the world in 2020

China, the most populous country, is taking a large piece of population share of 18.5% from the total world population of 7.74 billion.

In other words, for every 5.4 people in the world, 1 is from China.

That’s mind-blowing.

India, the country with the second-highest population in the world, is not far behind, raking 17.7% of the world’s share of population and has a fertility rate of 2.24, which is higher than China at 1.69.

Will India take over China to become the most populous country in the world?

Fertility Rate of the Top 20 Most Populated Countries in 2020 (Comparison)

Fertility Rate of the Top 20 Most Populated Countries in 2020 (Comparison)

DR Congo has the highest fertility rate at 5.96, followed by Nigeria at 5.42, Ethiopia at 4.3, Pakistan at 3.55, and Egypt at 3.33.

Out of 5, the top 3 and fifth are from Africa, and one is from Asia.

Land Size & Density of the Top 20 Most Populated Countries in 2020 (Comparison)

For Russia, despite having the largest piece of land in the world, the low birth and fertility rate limit the population growth, resulting in the lowest density among all other countries.

On the other side, Bangladesh has the highest density at 1265 P/km2 due to the smallest land area in the top 20 countries.

 

Summary (Detailed Table)

Here’s the summarized data of the top 20 most populous countries in 2020:

Summarized data of the top 20 most populous countries in 2020
 

7 Factors that Affect Country Population Growth

Many factors contribute to the country’s population count and growth rate.

And here are the 7 main factors that have significant impacts on the country population numbers:

  • Death rate
  • Infertile
  • Low birth and fertility rate
  • Economy
  • Government effort
  • Migrants
  • Urban to rural ratio
 

1. Death Rate

Common death-causing diseases like heart disease and stroke, which contribute a large percentage of all deaths in certain countries.

And if the deaths exceed births, the population will decline drastically in the long term.

Also, serious world crises like the coronavirus pandemic impacted the death rate significantly across multiple countries.

As of 2 May 2020, the death toll has crossed 238,628, with the United States the highest at 62,406, followed by Spain at 25,100, Italy at 28,710, the United Kingdom at 28,131, France at 24,724, and Germany at 6,649.

Which further reduces the total population in the Europe and Northern America region.

 

2. Infertile

Some countries are facing a high percentage of infertile due to poorly performed abortions.

 

3. Low Birth and Fertility Rate

Europe is the region with the oldest population, due to declined birth and fertility rates, which cause a shift in the population’s age profile and rising the median age of the country’s population.

If the birth rate falls below the level needed to maintain a stable population, it could lead to rapid aging and shrinking populations.

 

4. Economy

A country’s economic strength is one of the important factors to support population growth.

Raising a child to adult needs money, and an adult needs to work to earn money for food, drink, and shelter to survive.

It’s a realistic world.

Based on the survey, the financial burden is one of the common reasons why parents choose to have fewer children.

The improving economy will have a positive impact on the country’s birth rate.

 

5. Government Effort

Government effort is another important factor in the country’s population growth.

For instance, Italy has the highest ratio of elderly to youth in the world due to the low fertility rate.

Hence, the Italian government has put in the effort to reverse the downward trend by offering financial incentives to parents who have children and increase immigration to minimize the drop in the workforce.

In Greece, the government is offering cash incentives of 2,000 euros ($2,235) per birth to fight against the dropped fertility rate.

In some Islamic countries, the government is providing incentives like education subsidies, tax relief, and cash rewards to parents who gave birth and have more children.

The government also actively runs campaigns and seminars to educate the parents on the importance of giving birth to the country’s growth.

 

6. Migrants

Migrants are part of the population equation.

People immigrating and emigrating from the country will cause the country’s population to fluctuate.

For some countries, migrants are important to support the economy and fill the labor gap.

Certainly, countries with better financial standing, living conditions and loose immigration laws tend to attract more migrants.

On the flip side, countries with poor employment rates and low average wages will cause citizens to emigrate from their countries at large scale.

 

7. Urban to Rural Ratio

On average, urban areas tend to have a lower fertility rate than rural areas, mostly due to financial issues and education.

For instance, 

In our survey to the parents in both urban and rural areas, a majority of urban parents said they have used certain birth control and contraception methods, partly due to financial burden for raising a child, and partly due to time, as parents in the urban areas usually to have more demand in lifestyle, meaning they have lesser time to give birth and raise a child.

For rural areas, life is simpler and the living cost is lower, which promotes birth rate indirectly.

Besides, most of the parents in rural areas lack contraception knowledge, which causes a higher fertility rate from each family.

In some parts of the world, women in rural areas have no or minimal access to job opportunities, and the main job as a woman is to give birth and raise children.

 

Conclusion

The world population is on the growing trend from 1955 to 2020.

World population trend from 1955 to 2020

But it’s not the case for all the countries.

Some countries are growing rapidly in their populations, but some are facing a decline in their populations.

A country’s population is crucial to ensure healthy growths on workforce, economy, 

Shrinking in population is a serious issue that has to be tackled to protect the country from vanishing in the future.
