It’s simply the total number of people divided by the total land area. the total population in proportion to the area of arable land. example would be Egypt. Physiologic population density is more accurate because it shows arable’ livable land and it’s more realistic.

Physiological density is the number of persons per unit of agricultural land. This measure of density is useful, because it can give us a rough estimate of how many people an area of farmland can reasonably support. Physiological density is also helpful when studying population pressure and overcrowding.

Arithmetic density lets us understand where urbanization is occurring and the pressures people place on land in areas that are not urban but are still very densely populated. Understanding agricultural density lets us keep track of where domestic food sources are and how many farms are in operation.

We know that the higher the physiological density is, the more pressure people put on the land to produce enough food to survive. It also suggests that the available agricultural land is being used by more people, and it may reach its output limit sooner than a country that has a lower physiological density.

Physiological Density Around the World Singapore tops the list when it comes to countries with the highest physiological density, at nearly 4 times that of the second highest (Hong Kong); Singapore has a density of 440,998 per square kilometer of arable land.

Developed countries have lower agricultural density’s because technology and finance allow few people to farm extensive land areas and feed many people. Provides insights into the relationship between the size of a population and the availability of resources in a region.

The physiological density or real population density is the number of people per unit area of arable land. A higher physiological density suggests that the available agricultural land is being used by more and may reach its output limit sooner than a country that has a lower physiological density.

Arithmetic density, also known as real density, is very simply the total number of people divided by the total land area. Physiological density is the number of people per unit area of arable land.

the number of people per square mile of arable land. Which country has a low arithmetic density, but a high physiological density? United States, Egypt, United Kingdom, Nigeria, India.

Examples of countries experiencing negative population growth include the Ukraine, Russia, Belarus, Hungary, Japan, Italy, and Greece.

According to the Population Reference Bureau, Austria and Russia had zero population growth rates in 2014. The following countries had growth rates within one tenth of zero: Slovenia, Spain, Italy, Greece, Bosnia-Herzegovina, Slovakia, Belarus, Monaco, Estonia, Finland, Denmark, and Taiwan.

The table below shows 20 countries with a negative population growth rate between 2015 and 2020 as per United Nations data….Countries With Shrinking Populations.

Latvia. Latvia’s population is projected to drop from 1.9 million in 2020 to 1.5 million in 2050 (21.6% decline). The decline is caused by both negative natural population growth and a negative net migration rate.

When a population grows, its growth rate is a positive number (greater than 0). A negative growth rate (less than 0) would mean a population size gets smaller, reducing the number of people inhabiting that country.

Taiwan Native Hawaiian and Pacific Islander women had the highest fertility rate of any ethnicity in the United States in 2019, with about 2,178 births per 1,000 women. The fertility rate for all ethnicities in the U.S. was 1,729.5 births per 1,000 women.

In general:

• women are most fertile before the age of 30.
• after 30, women’s fertility starts to decrease.
• after 35 fertility declines more significantly.
• by 40, a woman’s fertility is about half the level it was before she was 30.

As of 2010 about half of those living in poverty are non-Hispanic white (19.6 million). Non-Hispanic white children comprised 57% of all poor rural children. In FY 2009, African American families comprised 33.3% of TANF families, non-Hispanic white families comprised 31.2%, and 28.8% were Hispanic.
