Population Patterns
What do we call the number of people living in a particular area?
Population Density
Which DTM stage has high birth rates and high death rates?
Stage 1
What do we call people moving into a country to live there?
Immigrants
Coal, oil, and natural gas are examples of what type of resource?
Nonrenewable resources
What population measurement estimates the average number of years a person is expected to live?
Life expectancy
Which type of density compares a country's total population to its total land area?
Arithmetic Density
During which DTM stage do birth rates begin to decline?
Stage 3
What do we call people leaving their country to live somewhere else?
Emigrants
What theory argues that humans can adapt to their environment using technology and innovation?
Environmental Possiblism
What rate measures the number of babies who die before reaching age one?
Infant Mortality Rate
Which type of density compares the number of farmers to the amount of arable land?
Agricultural Density
Which DTM stage typically has low birth rates, low death rates, and slow population growth?
Stage 4
Someone moves to another country for better job opportunities. Is this a push or pull factor?
Pull factor
What theory suggests that the natural environment strongly influences human behavior and development?
Environmental determinism
What rate measures live births per 1,000 people per year?
Crude Birth Rate (CBR)
A country has 20 million people and 5 million square miles of land. What is its arithmetic density?
4 people per square mile
Why does a country's population often grow rapidly during Stage 2?
Death rates decrease while birth rates remain high.
The U.S. government forces a Native American community to leave its ancestral homeland. What type of migration is this?
Forced Migration
A town limits water use during a drought to protect its water supply for future generations. What concept does this demonstrate?
Sustainability
A country improves access to education, healthcare, and technology. What broad process is it working toward?
Development
What is the term for the difference between a country's birth rate and death rate?
Natural increase rate
A country has low birth rates, low death rates, and an aging population. What population challenge might it face?
A shrinking workforce or increased costs for elderly care and pensions.
What is the difference between a refugee and an internally displaced person?
A refugee crosses an international border to seek safety; an internally displaced person remains within their own country.
Why is arable land important when studying agricultural density?
It is land suitable for growing crops, so it helps show how many farmers work on available farmland.
Why might a country with a rapidly growing population struggle if its schools, hospitals, and job opportunities do not grow too?
Its resources and services may not be able to meet the needs of its growing population.
