China and India are the top two most populated countries in the world, based on their respective percentages. The USSR and Japan round out the top five. Europe, including France and Germany, is ninth and Italy is not included in the list. These countries have the highest populations, with the US and Europe accounting for more than half of the world’s population. If we look at absolute gains, India, China, and South Africa rank second and third, respectively.
China
According to the latest population statistics, nearly half of the world’s population resides in the top 10 most populated countries. 
The largest among these is China, which is currently the most populous country, but India is projected to overtake it by 2027. The world’s population is growing at an average rate of about 1.2 percent per year, according to the United Nations. The trend is unlikely to slow, however.
The population of China will reach 1.6 billion by the mid-twentieth century. After this peak population, it will gradually decrease. The overall social dependency ratio in China will also decline. With a large labor force and low fertility rates, China will have the greatest need for a high-quality educational system and health care. The goal of the Chinese Government is to make its population healthier, more educated, and more sustainable.
India
The most populated countries in the world are China, India, and the United States.
These countries make up more than half of the world’s population, with India expected to overtake China as the most populated country by 2027. Other popular populated countries include Brazil, Indonesia, and Nigeria. India is also a major producer of rice, wheat, cotton, and groundnuts. Its agricultural sector is thriving, and it accounts for about one-tenth of global crop production.
With a population approaching 1.4 billion, India will soon surpass China as the most populated nation in the world. In just over a decade, it will surpass China in size. However, as population increases, it is crucial to remember that this is just a snapshot of today’s demographics. The United Nations has warned that countries with a high fertility rate may suffer from a lack of resources and the consequent dwindling resources.
South Africa
The country of South Africa occupies the southern tip of Africa and has coastlines on the Indian and Atlantic oceans. 
It has a rich history of immigration and has long expressed xenophobic sentiments towards newcomers. This country has also been a victim of high economic and social inequality, stratified primarily by race. In fact, more Black people than any other ethnic group live below the poverty line. The country also has a high unemployment rate.
The country has experienced a steady but rising brain drain. Despite this, South Africa has remained a magnet for regional migration. It has struggled to resolve external pressures and has flirted with measures to limit immigration. Despite its economic challenges, South Africa remains one of the top 10 most populated countries in the world. The following chart highlights the most common migration patterns within the country and across borders.
Uzbekistan
The population of Uzbekistan is estimated at 9 million, making it one of the world’s ten largest countries. The country is also home to one of the largest media markets.
In 2000, there were 31 banks in Uzbekistan. Of these, only four were private. In addition, government regulations and controls on foreign investments hinder foreign investment. The overall investment climate in the country is still weak, with a simple average tariff rate of 4.7 percent.
The country is located in Central Asia and is bordered by Kazakhstan, Kyrgyzstan, Tajikistan, and Afghanistan. It was previously part of the Soviet Union and the Russian Empire before gaining independence in 1991. It is one of the most populous in the world and has a diverse economy, despite its remote location. International human rights groups and Western governments have criticised the country’s government, saying it is “extremely authoritarian.”
Mexico
A country in southern North America, Mexico shares borders with the United States to the north, the Pacific Ocean to the south, and Guatemala, Belize, the Caribbean Sea, and the Gulf of Mexico. 
The country has a total area of 1,972,550 square kilometers, making it the thirteenth largest country in the world. It has a population of 126,014,024 people. Mexico is a federal republic with 31 states, including the capital city, Mexico City.
In addition to being the most populous country in the world, Mexico has a diverse cultural and linguistic landscape. Famous Mexican authors include Samuel Ramos, Octavio Paz, and Carlos Fuentes. The country’s most famous art form is the mural, which is often based on pre-Columbian cultures. Mexico also has a thriving film industry, with many actors receiving international recognition. The country also has a small but vibrant Buddhist population.
