Most Populated Cities in the World by 2020


Improving housing standards as the world population increases is a global challenge, but the problem is that population growth is not evenly distributed across the globe making housing and general accommodation more difficult in the most urbanized cities of the world.

Overcrowded cities create huge problems for the provision of adequate housing but the capacity of sustainable accommodation is a crucial factor for a city to maintain economic growth.  Governments of countries are constantly under pressure to develop more land to build suitable homes.  The world’s most populated cities include:

Country                       Million

Tokyo                        37.28
Mumbai                     25.97
Delhi                          25.83
Dhaka                        22.04
Mexico City                21.81
Sao Paulo                  21.57
Lagos                         21.51
Jakarta                       20.77
New York                    20.43
Karachi                       18.94
Calcutta                      18.54
Buenos Aires              15.48
Cairo                           14.02
Metro Manila               13.40

Although Tokyo’s population is projected to decline, it remains the world’s largest city with 37 million inhabitants, but it is Mumbai, which is the most crowded city, which has 101,066 people in a single square kilometre - more than any other city in the world, quite a lot of people taking into account that the earth has an area of about 500 million square kilometres, which means the average population density is about 13 people per square kilometres and one square kilometre is about 225 acres!

Controlling and managing the most urban cities in the world has become one of the most important challenges of the 21st century; currently 54% of the world’s population lives in urbanized regions and this is expected to increase to 66% by 2050.

Cities are not only important for a country’s economic growth but possess unique cultural and architectural qualities, which act as a symbol for a country’s individual creativity. However, all cities face different challenges depending on the composition of their population, employment and the availability of suitable housing.

The world’s urban population is growing and cities need to plan more sustainable homes to accommodate their citizens, a decent home means a decent environment.  People constantly interact with their environment and is central to creating quality of life.
