The most densely populated cities in the world
The modern rhythm of life dictates the conditions that 100 years ago even imagine it was impossible. Most of humanity strives to live in the big cities, so the population density (number of people living in one square kilometer) is constantly growing. In the most populated city in the world today is home to as many people as were in all of North America in 1850.
The capital of the Philippines, the most populous metropolis in the world. Having a small area of 38.5 km2, the town has a population of 1.66 million people, which is unprecedented density — 43 079 chelkm2. To imagine such crowding is quite difficult – it’s like if you put all residents shoulder-to-shoulder in a cube with 20 manpower lines located one above the other. And in a separate district, No. 6, marked density 68 266 chelkm2.
The most populous city suffers from the typical environmental problems through inadequate infrastructure of Manila. Within the city there are several dead rivers, and the largest, Manila, daily (!) reset to 200 tons of waste. Besides, open dumps, air pollution from transport and industrial wastes. Only 10% of wastewater that is purified. Traffic jams contribute thousands of tons of emissions into the atmosphere, which exceeds all acceptable norms.
Formerly Bombay, the largest city of India with a population 12,48 million people. The capital of Maharashtra is in second place in population density in the world — 21 665 people per square kilometer.
Mumbai is a city of contrasts, where luxury coexists with poverty at every step. It is the largest port in India and the largest hub of international communications, through which half of all passengers in the country. It is a cosmopolitan city, where peacefully coexist the Asian and European culture. Interestingly, the crime here is moderate, despite the huge number of visitors on earnings of men.
Environmental problems not over Mumbai — the level of clogging of the river Ulhas in some places reaches 80%, as the urban waste water does not undergo preliminary cleaning. The degree of air pollution exceeds the norm by 3 times and affects the lungs as Smoking 10 cigarettes (per day).
The population of 2.24 million people, resides in the territory of 105 km2, the density is 21 289 chelkm2. In Paris most of the inhabitants are young people, and the number of foreigners is 15%. A city that can be explored on foot in a few hours, experiencing all the delights of a huge metropolis.
Smog, noise and transport emissions, the lack of green areas — the main problems of Paris. But the government is trying to address these issues: the trees are widely planted on rooftops, water quality in the Seine in recent years has improved considerably.
All industrial production is gradually moved outside the city, thereby reducing soil pollution. Every day above the city runs a special probe, the color of which changes depending on the composition of the air. And the data can be seen on many boards of city, along with temperature and time.
Autonomy in the PRC where an area of 27 square kilometers inhabited 541 thousand people, accounting for density — 20 044 chelkm2. The former island became a Peninsula due to drainage of coastal areas. Interestingly, in one of the most densely populated cities in the world are very low, the birth rate is 9 births per 1,000 inhabitants. But the main increase in population is due to migration.
The city’s economy is built due to gambling (70% of city budget), textile and tobacco industries, and fishing. The unemployment rate is low — 4 %, overall literacy is high — 95% of the population.
A small country, one of the most densely populated in the world, which at 2 square kilometers live 35 986 people, representing a population density of 18 285 chelkm2. Main revenue sources in the state: gambling, tourism, and shed light on the life of the Royal family. The new inhabitants of the territory quite successfully trying to take the sea for the construction of residences on concrete Islands.
The capital of Catalonia is no exception — 1.6 million inhabitants compactly settled in the area of 100 km2, which amounted to a density of 16 056 chelkm2. The size of Barcelona is bounded by two rivers and a mountain range, so grow it only in height.
It is a large industrial city, cares about the environment — many new products that reduce harmful effects on the planet are successfully used in construction. New roads put of photocatalytic concrete absorbs nitrogen oxides and turn them into harmless compounds. The roads are covered with stones, without electrical energy, using only solar. Citizens care about the environment — they are massively transferred to the bikes, and the government made concessions by increasing the number of bike lanes at the expense of car lanes. Actively greening the roofs of the houses.
The capital of Bangladesh, which is the world’s largest river Delta, catastrophically overpopulated. A population of 9, 72 million people live in the area of 816 km2, the density in 11 918 persons per km2. And this is only according to official (and unofficial — twice). The country is on 169 in the world in the index of eco-efficiency, which is determined by the criteria of health and ecosystem vitality.
The literacy rate is quite low — 68%, one third of residents live below the poverty line (up to $ 5 per day). The main form of transport — Moto-rickshaws that serve as the cause of traffic jams. A large percentage of the population uses the river as a vehicle, which adversely affects its condition — all the tourists notice the incredible smell of the water. River banks resemble a dump, with tons of debris, not cleaned in years. You should add the constant floods and other natural disasters, to cope with which the government comes out with varying success.
The Republic Of Singapore
A city-state situated on 63 Islands, which limits its area (718 km2) and creates a population density of 7 437 chelkm2. Here is the program of the alluvium of territories, through which gradually increases the Lion city.
This country in 30 years has managed to solve many of their problems and become a developed country with high living standards. In the 60-ies of the inhabitants of the imported drinking water and sand for construction, and now the amount of banking assets in Singapore have overtaken Switzerland. Here, the transparent market system and the almost complete absence of corruption (Singapore salary of judges is about $ 1 million per year). The crime rate is very low, for drugs and murder — the death penalty.
5% of the territory of Singapore the conservation area. That there know how to take care of the environment is the fact that the city is on the 5th place in the world by the index of environmental efficiency.
In the capital of Japan is home of 13.37 million people with a population density of 6 108 chelkm2 that due to the geographical location of the city — it is located on Honshu island with several small around. Projects to create artificial Islands gradually come to life, the only opportunity to expand the area.
The city is located in the seismic zone and had some questions about the transfer of the capital to a safer place. The government is trying to make the lives of the inhabitants of the metropolis,which ranks third in the country in the number of diseases associated with environmental problems, easier — taxis, green roof gardens, oxygen tanks on the streets for children.
However, according to the survey of the British magazine the Economist in the year 2015 Tokyo is recognized as the safest city in the world.
Interestingly, the most populated city in the world, which at the moment reside 24.2 million, has a density of only 3 809 persons / km2. This Chinese port city became an important financial and industrial centre for over 200 years from a small fishing village.
The prerogative of the current construction in the city is the skyscraper, which is understandable in such a metropolis. The number of skyscrapers is a main Chinese city — there is the famous Shanghai tower (128 story building, the second in the world).
Despite the high population density and the number of visitors, the city is a very small percentage of crimes towards foreigners.
Now the man for the blessings of civilization and the opportunity to live in the most densely populated cities in the world have to pay. And if the advanced economies have the means to make the lives of the inhabitants of the metropolis are better then third world countries serve as a good example of real monsters, destroying all life…
