Population Concentrations
Are human beings distributed uniformly across the Earth’s surface?
No
What are the four regions where most of the world's population lives?
East Asia, South Asia, Southeast Asia, and Europe
What is population density?
The number of humans within a given unit of area
What is land suited for agriculture called?
Arable land
What is agricultural density?
Agricultural density is the ratio of the number of farmers to the amount of arable land
How many sections can the world be divided into?
7
What percentage of Europe's population lives in cities?
Three-fourths (75%)
Which country has the highest arithmetic density?
The Netherlands
What does physiological density represent?
The number of people per unit area of arable land
Why do countries in higher stages of economic development require fewer farmers?
Countries with higher economic development can access more sophisticated technology, which allows them to produce higher crops yields with fewer people
How many people approximately are there in each section of the world?
1 billion
What are some of the physical environments that are too harsh for human habitation?
Too dry, too cold, too wet, or too mountainous
Why is physiological density often more useful than arithmetic density?
Physiological density is often more useful than arithmetic density because it measures the number of people per unit of arable land rather than total land area
How does comparing physiological and arithmetic densities help geographers?
It helps them understand the capacity of the land to yield enough food for the needs of people
How can two countries have similar physiological densities but different agricultural densities?
Even if two countries have similar physiological densities, their agricultural densities can differ based on how many farmers are needed
What was the population approximately in Egypt?
50-99 million
Why are cold lands near the poles sparsely populated?
Because they are perpetually covered with ice or permafrost, making it difficult to grow crops and build permanent settlements
Which regions of the world have the highest population density?
The highest population density regions include, South Asia (India, Bangladesh), East Asia (eastern, China), and parts of Europe (e.g., the Netherlands)
What percent of Egyptians don’t live in the Nile River valley or delta?
5 percent
What conclusion do geographers draw about the Dutch and Egyptian agricultural systems based on their densities?
Both the Netherlands and Egypt have high physiological densities, meaning they put heavy pressure on their land for food production. However, the Dutch agricultural system is more efficient because it requires fewer farmers compared to Egypt.
How does a cartogram depict the size of countries?
Population
What is Ecumene, and how has it changed overtime?
The ecumene is the portion of the Earth's surface occupied by permanent human settlement. It has increased over time as humans have developed tech, and adapted to new enviorments
How might differences in agriculture density affect food production and economic development in countries like Egypt?
Egypt has a very high agricultural density (221 farmers per square km), indicating that a large portion of the population is engaged in farming, possibly due to reliance on the Nile River for arable land
Why do most Egyptians choose to live in the Nile River or Delta?
Those places are the only areas in the country that receive enough moisture to allow intensive cultivation of crops
How might agricultural density impact a country's economic development and food security?
A high agricultural density in a developing country may indicate a labor-intensive agricultural system with lower efficiency, potentially leading to food insecurity and economic struggles
