As the population grows, the world faces many challenges. When there are more people in this world, they will need more resources, more food, water, and land to survive.
Happily, population growth is declining, and in some lands, the population is declining. But there are still areas where the human bomb is about to explode. Let us tell you about the 10 most populous urban areas in the world:
As the population grows, the world faces many challenges. When there are more people in this world, they will need more resources, more food, water, and land to survive.
Karachi, Pakistan
Population: 1 crore 91 lakh 65 thousand
One-fifth of Pakistan's urban population lives in a "large town" that was once the country's capital. By 2019, the population of Karachi has grown by 2.2% and living standards continue to decline. Violent crime, inequality, and economic instability. Karachi is one of the most densely populated cities in the world.
Mumbai, India
Population: 2 crore 4 lakh 11 thousand
The second-largest city in India, but also the largest in the city center in terms of population alone is 13 million. How big is Mumbai? Estimate this by saying that trains running in the city alone reach 6 million people every day. That number is enough to cover the busy lives of any city in the world. Over the past 20 years, the population of Mumbai has grown rapidly since doubling since 1991. That is why the city situation is getting worse. 41% of the people of Mumbai and suburbs live in slums. Mumbai is still growing, but the standard is lower than before.
Beijing, China
Population: 24.62 million
China's second-largest metropolitan area, with more people than a large country like Australia. Not only has the population grown steadily since 1975, but it is expected to grow by 2035. With so many people, Beijing's biggest problem is air pollution. The air is very polluted, due to the overcrowding of coal-fired plants and cars on the outskirts of the city.
Cairo, Egypt
Population: 29 million
The capital of Egypt, located on the banks of the Nile River, has been under construction since at least the fourth century. The city grew rapidly after the outbreak of the disease during the Middle Ages and the great uprisings of the modern era in the 1950s. Even the population of the inner-city population has grown to over 12 million. Alexandria, Egypt's second-largest city, has only 30% more people than Cairo.
Dhaka, Bangladesh
Population: 21 million 5 thousand
Dhaka is the most populous city in the world and still thriving. It has over 23,000 people per square mile and 2,000 people move to the city every day. The reason is simple, natural disasters due to climate change have caused great damage in rural areas. That is why a quarter of the world's population lives below the poverty line. In Dhaka alone, about three million people live in slums.
Mexico City, Mexico
Population: 2 crores 17 lakh 82 thousand
The center of the world economy is Mexico City, one of the largest and most populous cities in the world. 20 percent of the population of Mexico lives in the city. Population growth means difficulties in providing essential services, but there is still a glimmer of hope as the city's population has grown by only 0.5% between 2019 and 2020.
Sao Paulo, Brazil
Population: 22 million 43 thousand
The largest city in both South and North America, with a city center with a population of over 11 million. It is a highly complex, diverse, and international cultural center with a population of 26 billion. It is also a refugee city, and 81% of the students are descendants of immigrants. The city's population will exceed 23 million by 2030.
Shanghai, China
Population: 27 million 58 thousand
Shanghai is the largest natural city in the world, and also the fastest growing city in 20 years, having grown almost twice a year since 1992. It is still growing, but it is shrinking. Experts predict that the population of this metropolitan area will reach 50 million by 2050, which will no doubt exacerbate all the problems that congested cities face, such as inadequate infrastructure and pollution problems.
Delhi, India
Population: 32.9 million
Delhi is the capital of India and one of the most polluted cities in the world. With an area of 1,484 square miles, it has more than 11,000 people per square mile and is growing faster than any other city in the world. In 2011 alone, the population increased by 2,15,000, and 2.85,000 people moved to the city. Although population growth in 2019 was 3.03 percent, it will still exceed the 43 million mark by 2035.
Tokyo, Japan
Population: 37.39 million
Believe it or not, the population of the world's largest city dropped by 0.11% in 2019. The trend is expected to continue, and by 2035, 16 years from now, the population of Tokyo will have dropped by 1.5 million. Needless to say, this is a practice that should be practiced in other major cities of the world, to reduce pressure on them.
