How do you interpret population density?

Population density is a measurement of the number of people in an area. It is an average number. Population density is calculated by dividing the number of people by area. Population density is usually shown as the number of people per square kilometer.

Overpopulation in China began after World War II in 1949, when Chinese families were encouraged to have as many children as possible in hopes of bringing more money to the country, building a better army, and producing more food.

Population density allows for broad comparison of settlement intensity across geographic areas. In the U.S., population density is typically expressed as the number of people per square mile of land area.

In fact, density can actually be good for us and is proven to have many surprising health and environmental benefits. One study found that living in more compact, dense areas versus more sprawling areas makes a difference of about two-and-a-half years in life expectancy.

The population density refers to the number of people per unit area which can be computed as square meter or kilometer. … This is done to be able to properly assess the characteristics and real needs of the population so the programs to be created will surely answer the needs of the people in the place.

Among the bigger states in terms of land area, Bihar has the highest population density of 1,102 persons per sq km and occupies the 6th rank, followed by West Bengal, Kerala and Uttar Pradesh in that order.

A high population density implies that the population is high relative to the size of the country. … However, others are concerned that a rising global population density could lead to a strain on resources, leading to food shortages, congestion and loss of the environment.

Physical factors that affect population density include water supply, climate, relief (shape of the land), vegetation, soils and availability of natural resources and energy. Human factors that affect population density include social, political and economic factors.

Population growth is based on four fundamental factors: birth rate, death rate, immigration, and emigration.

Population density can have a negative impact on our environment and natural resources. These pressures can lead to deforestation, result in overcrowding, and could lead to the destruction of our planet’s delicate ecosystem. Growing populations use large amounts of nonrenewable resources like timber, coal, and oil.

The special administrative region of China known as Macau has the density of population of 20.

According to the World Bank, the aging population and low fertility rates are to blame for the increase in population as 36 percent of the world’s population over 65 currently live in East Asia.

In late October 2015, China announced it would end the one–child policy. … A second child would place even more restrictions on my career,” she said. Nearly five years since the two-child policy came into force, China’s fertility level is still below what is required to keep the population at its current size.
