Population Density facts

While investigating facts about Population Density By Country and Population Density Definition, I found out little known, but curios details like:

Despite supporting one of the highest human population densities, Japan is the first developed country with the highest percentage (74%) of forest-covered land. Japan's forest management policy began over four centuries ago.

how population density is calculated?

The Netherlands, which fits into the U.S. more than 200 times and has a population density higher than Rhode Island, is the world's second largest food exporter.

What population density is considered high?

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what population density means. Here are 50 of the best facts about Population Density By State and Population Density Map I managed to collect.

what's population density?

1. The entirety of the world's population(6.7 billion in 2011) would be able to fit into a city the size of Texas if the population density was the same as New York.

2. The population density of Manhattan is much lower today than it was 100 years ago, and total population has fallen by about 25%

3. The Netherlands is the world's second-largest exporter of food and agricultural products, after the United States despite having one of the largest population densities of the world.

4. If Texas had the same population density as New York City, all of the world's 7.4 billion people would fit inside the state's borders.

5. The most densely populated area to ever exist on earth was a largely self-governed, crime-infested block in Hong Kong. Called Kowloon Walled City, it had a population density of 1,255,000 people per square kilometer

6. There is an island in the Pacific of 300 people, no longer than 750m, where a Polynesian people live at a population density equalling that of Bangladesh. The fact that the island's ecosystem hasn't been negatively impacted has attracted the attention of sustainability scientists.

7. Population density and political preference go hand in hand; people living in high density areas tend to vote liberal whereas people living in low density areas tend to vote conservative.

8. In 1972 a scientist created a 'Rat Utopia' as a social experiment to study population density, and within two years the population dived Into a irreversible decline unto extinction.

9. There was once a city within the city of Hong Kong that was largely ungoverned and had a population density of 1,255,000 people per square km.

10. The 40 most densely populated cities in the world, 3 of them are in New Jersey. Other cities with comparable densities include Kolkata and Cairo. No other American cities are on the list.

Why population density is low?

You can easily fact check why population density high by examining the linked well-known sources.

India is only 109th in real population density, as such a high percentage of the land is arable. There is roughly the same amount of farmable land in India per Indian as there is in Germany for each German.

Kowloon Walled City -- a bygone, ungoverned Chinese city with a population density of over 3 million people per square mile - source

Locusts are just regular grasshoppers that swarm when excessive population density causes their legs to be touched so much that their brains release excess serotonin - source

Before it was demolished, Kowloon Walled City had a population density of over 3,000,000 people per square mile. A lawless squatter metropolis, it had high rates of gambling, prostitution and drug use.

When population of lemmings in certain area becomes too large, they migrate in large numbers toward new areas to find food. These migratory movements are responsible for the widespread myth that adult animals intentionally jump off the cliffs in large numbers to reduce population density and leave the remaining food sources for the next generation of lemming.

When is population density high?

There are more than five million people living in Nuevo Leon, making it eighth most populous Mexican state. Because the majority of those people live in the Monterrey metro area, the is fourteenth in density.

How population density is measured?

Females can lay eggs two times per year or once every few years, depending on the density of population.

Half of all Canadians live south of Seattle. Though Canada's population density is low, many regions in the south such as the Quebec City–Windsor Corridor, have population densities higher than several European countries.

If Canada had the same population density as Singapore, the population of Canada would be 79,800,000,000 (79.8 billion) which is ten times the world's current population.

Sonora is eighteenth among all Mexican states in population with more than 2,800,000 people. Due to its large physical size, though, it is twenty-seventh in density among Mexican states.
