30 Most Crowded Cities in the World

Grant Suneson

The world’s population continues to increase, especially in its cities. By 2050, it is estimated that 66% of people in the world will live in urban areas, compared to 54% today. These more populated areas offer better educational opportunities, greater access to health care, and promising career prospects.

While there are many advantages to living in large cities, the constant influx of new residents can result in significant challenges to urban development. People packed into small spaces exacerbates pollution and other health issues, taxes public transportation infrastructure, and drives up the price of living.

Despite these problems, the allure of the big city is still enticing for many, forcing some urban centers — and the major metropolitan areas surrounding them — to take on more people than they were originally designed to handle.

To determine the most crowded cities in the world, 24/7 Wall St. reviewed the United Nations’ Demographic Yearbook and ranked the cities on the number of residents per square mile.
