The United Nations prepared a report recently which estimates that the human population on earth will exceed 9.6 billion by the year 2050. It added that in the next 50 years after 2050, the rise would be above 10.9 billion. A large part of the population rise is expected to be in the least developed and poor countries that have the lowest per capita income. An enormous rise is expected in the sub-Saharan regions in countries like Nigeria, Afghanistan, Uganda, and Congo. In these countries, women still give birth to around 5 to 6 children in the family. In richer countries that are developed and economically stable, women give birth to fewer than 2 children. Here are the top 10 most populated countries in the world as of now:
Top 10 Most Populated Countries of the World
China has a huge population, with a relatively small part of it being the youth. This is mainly due to the one child policy implemented by the government. The population of the country crossed the 1 billion mark in the year 1982. As per the latest census reports, the population of China is more than 1.355 billion. This is the largest among all countries of the world. 91.51% of the population is of the Han Chinese, and 8.49% were minorities. The population growth rate of the country is just 0.47%, which ranks it 159th in the world.
For many centuries, China has maintained its position as the most populated country in the world. From the beginning of the 1950s, several population control and family planning campaigns had begun in the country. The fast growing population was a matter of concern for the government.
India is the second among the most populated countries in the world with a total population of over 1.27 billion people. This is more than a sixth of the total population of the world. By 2025, India is expected to become the largest populated country in the world by crossing China. By 2050, the population is estimated to reach 1.6 billion. The population growth rate is 1.2%, which ranks India 94th in the world. It was in the year 1998 that the population of India crossed the 1 billion mark.
More than 50% of the population of India is under the age of 25, and more than 65% is below the age of 35. The average age of an Indian is expected to be 29 years in 2020. The population in India is diverse, ranging across different ethnic groups, religious groups, and even races. Africa is the only continent in the world that exceeds the genetic, cultural, and linguistic diversity found in India.
The total population of the United States is 320,480,000 as calculated in March 2015. This makes it the third most populated country in the world. 81% of the population lives in the cities and suburbs, making it a very urbanized nation. The most populous states are California and Texas. The most populous city is New York. The rate of population increase was found to be 0.75% in 2012. This is high when compared to the other industrialized countries, but low as compared to the world average of 1.1%. Over a quarter of the population consists of people under the age of 20 years. 12.8% was found to be above 65 years. The national median age is 36.8 years.
The 2010 national census claims the population of Indonesia to be 237.6 million. 58% of this population lives in the island of Java, which is known to be the most populous island in the world. Since 1967, Indonesia has been implementing a really effective family planning program. Even then, the population is expected to surpass that of USA and become the third largest in the world by the year 2043. The population growth for the country was 1.49 % for the decade ending in 2010. Many people are of the opinion that the family planning system already existent needs to be revitalized to avoid becoming the third in the list of most populated countries in the world. But, this has got opposition from religious based opinions that believe family planning is against the wishes of God.
There are a number of ethnic and linguistic groups in the country. Indonesia, which is a form of Malay language, is the most commonly used language for education, government, communication, and business purposes. There are a number of local ethnic languages that are the first language for most citizens, and they are still important.
The population of Brazil is quite diverse, consisting of a number of races and ethnic groups. The origins of Brazilians come from four main sources – Amerindians, Africans, Asians, and Europeans. Since 1872, Brazil has been conducting a periodical population census. It has been carried out decennially since 1940. All through the period of history, there have been a lot of ethnic and racial admixture, and also the assimilation of cultures and syncretism in the country of Brazil.
The Brazilian Statistics bureau reports a total population of 189,953,000 inhabitants in the country in the year 2008. The 2010 census calculates it to be 190.8 million. It is currently the fifth most populated country in the world.
Majority of the inhabitants of Brazil live within a radius of 300 kilometers from the coast. The interiors in the Amazon basin are mostly empty. As such, the population distribution is found to be quite uneven. The interiors are sparsely populated, and the coast is densely populated. There has been a small change in this pattern by the movements into the interiors in recent years.
The population of Pakistan is estimated to be over 199 million in the year 2014. This makes it the sixth most populated country in the world. The urban population of country increased by seven times during the years 1950 to 2011. The total population increased by four times during this period. There has been a high growth rate in the population of the country in the past years. This has been changed by the moderate birth rates. In 2014, the population growth rate was calculated to be 1.49%.
The Pakistani society is multicultural and multi-ethnic. It consists of the largest refugee populations in the world, and also a young population. 50% of the population resides in towns that have 5,000 people or more.
Nigeria is the most populous country in Africa, and it accounts for almost a sixth of the total population of the continent, or a fifth of the Sub-Saharan African population. Around 50% of the total population lives in urban areas. At least 24 cities of the country have a population of over 100,000. There are a total of 399 ethnic groups in the country, which has formed a diverse range of customs, languages, and traditions. This makes it the seventh among the most populated countries in the world.
English is used as a common language for communication among the different ethnic groups. Knowledge of at least two or more Nigerian languages is widespread among the population. The most commonly used languages are Hausa, Yoruba, and Igbo.
High fertility rates have given rise to a population explosion in Nigeria for the last 50 years. This quadrupled its population.
The Bangladeshi population is largely ethnically homogeneous. 98% of the population is of the Bengali ethno-linguistic group, giving it the current name. Diverse indigenous people are found in the Chittagong Hill Tracts, Sylhet, Mymensingh, and North Bengal divisions. All through the region, there are a number of dialects of Bengali spoken among the people. The people of Chittagong and Sylhet speak a distinctive dialect.
The population of the country was estimated to be around 160 million in the year 2013. Around 89% of the population consists of Muslims. This is followed by Hindus at 8%, Buddhists at 1% and Christians at 0.5%. Bangladesh is also known to have the highest population density in the world.
The official estimate for January 1, 2015, reports the population of Russia to be 146,270,033. The population of the country hit a historic peak in the year 1991, with a total of 148,689,000. This was just before the Soviet Union broke down. After that, there has been a decade long decline. The population fell at a rate of 0.5% per year with declining birth rates, increasing death rates, and also due to emigration.
The decline was seen all through the late 2000s. Population growth was recorded for the first time in 15 years in the year 2009 with the addition of 23,300 people. The slow population growth in the country has been mainly due to improved health care systems, falling emigration, changing fertility plans, and also the influx of immigrants. The population further increased by 292,400 people in the year 2012.
The census of October 2010 reports the population of Japan to be at one of its peaks, which was calculated to be 128,057,352. The estimate was recorded to be 127,650,000 in March 2012, which makes Japan the tenth largest populated country in the world. The high growth rates in the late 19th and early 20th centuries are the main reasons for the high population size in Japan.
Falling birth rates, and almost no immigration has led to a population loss in the recent years. The country is known to have the highest life expectancy rates in the world, at 81.25 years, as recorded in 2006. Estimates suggest that the population of the country will keep declining by one million every year. By 2060, the population is expected to stand at 26 million.
