On our planet, we have as many as 195 countries.

With 7.5 billion people living on Earth in various countries, it is clear there are too many of us. The population imbalance with regard to land is something that might send a chill down your spine for all the legitimate reasons.

Imagine an urban setup of a mansion where lives a family of five and a few blocks away, there is a slum where in each shanty, those of the size of one of the mansion's washrooms, lives a family of 10.

It is an old news that the majority of the world's population lives within a proportionally small circle that covers China, India, Japan, and other parts of Southeast Asia.

With 1.3 billion people in India, 1.3 billion in China, 127 million in Japan, Southeast Asia is crowded.

Southeast Asia is crawling with people as it is not just the three aforementioned countries. Countries like Cambodia, Laos, Myanmar, Malaysia are all part of Southeast Asia with their respective populations.

Comparing it with expansive regions like Canada, Russia and non-coastal USA, it is heavily packed since all-embracing areas hold close to 400 million people only, where India alone house 1.3 billion people.

POPULATION DISPARITY - GIANT, HUGE, HUMONGOUS, GIGANTIC, EXPANDED

The Business Insider found an interesting comparison.

Metrocosm -- a website of data visualisation expert Max Galka -- submitted an image which shows an extreme comparison of the density of population.

Bangladesh and three provinces in India - Bihar, Jharkhand and West Bengal, which are highlighted in red, take up just 415,000 sq km - that's smaller than two times the are of Uttar Pradesh in India. Together they hold more population than all of the blue territories on the map.

The population density of Dhaka in Bangladesh is 45,000 people per square kilometre.

India's fourth-most populous state has a population density of 1,029 people per square kilometre. Population density of Jharkhand is 414 people per square kilomtre and the population density of Bihar is 1,102 people per square kilomtre.

Now, if we see the population density of a US city, for example Califronia, it is 251 people per square kilometre. This comparison shows people have more land to roam around on as compared to Dhaka or West Bengal.

People living in cramped places have their own struggles. In India itself, we have countless footpaths, but not for people but for shops to flourish. Indians have mostly walked in the middle of the roads because we are crowded and footpaths are already taken.

In a bus meant for 30 people will be full of 50, because, again, we are too many. This also makes people of populous areas more adjusting since we are used to people, a lot of people.

FASTEST GROWING CITIES IN THE WORLD

The disparity gets intense as we check out the fastest growing cities. Here is the map of these cities showing the rate if new citizens per hour.

Dhaka which is the largest city in Bangladesh, is one of the fastest growing cities in the entire world. It has a growth rate of 74 people per hour.

Kolkata in India is also adding 32 citizens every hour.
