What is Arithmetic Density?
Total population divided by total land area.
What is Physiological Density?
Total population divided by arable land.
What is Agricultural Density?
Number of farmers divided by arable land.
Define Arable Land.
Land suitable for growing crops.
What are Push Factors?
Reasons why people leave their home country.
What are Pull Factors?
Reasons why people are attracted to a new country.
Define Midlatitudes.
The region between 30°N-60°N and 30°S-60°S.
What is a Population Pyramid?
A snapshot of a country's population by age and gender.
What is migration?
Movement of people from one place to another.
What is meant by 'population distribution'?
The pattern of where people live.
What is the Demographic Transition Model (DTM)?
A model that shows population changes over time, with stages based on birth and death rates.
How does climate influence population distribution?
Most people prefer moderate climates, typically found in the midlatitudes.
How does fertile land influence population distribution?
Access to arable land for growing food is crucial; people settle in river valleys and plains.
Explain the concept of 'stage 1' of the DTM.
High birth and death rates, stable population (pre-industrial societies).
Explain the concept of 'stage 2' of the DTM.
High birth rates, declining death rates, rapid population growth (early industrializing countries).
Explain the concept of 'stage 3' of the DTM.
Declining birth rates, low death rates, slower population growth (late industrializing countries).
Explain the concept of 'stage 4' of the DTM.
Low birth and death rates, stable population (developed countries).
Explain the concept of 'stage 5' of the DTM.
Very low birth rates, low death rates, population decline (some post-industrial countries).
What do bulges or indentations in a population pyramid indicate?
Past events like wars or baby booms.
How do economic opportunities influence population distribution?
Job prospects and economic growth attract people to certain areas.
Compare Arithmetic and Physiological Density.
Arithmetic density is total population/total land. Physiological density is total population/arable land; it shows pressure on land for food.
Compare Stage 2 and Stage 4 of the DTM.
Stage 2: High birth rates, declining death rates. Stage 4: Low birth and death rates, stable population.
Compare Push and Pull Factors of migration.
Push factors force people to leave; pull factors attract them to a new location.
Compare physical and human factors influencing population distribution.
Physical factors are natural elements like climate and land. Human factors are safety, economy, and social connections.
Compare population pyramids of countries in Stage 2 and Stage 4 of the DTM.
Stage 2 pyramids have a wide base and narrow top. Stage 4 pyramids are more rectangular.
Compare the focus of arithmetic density vs. physiological density.
Arithmetic density focuses on overall population distribution, while physiological density focuses on population pressure on arable land.
Compare the level of industrialization in countries in Stage 1 vs. Stage 4 of the DTM.
Stage 1 countries are pre-industrial, while Stage 4 countries are developed and highly industrialized.
Compare the birth rates in countries in Stage 3 vs. Stage 5 of the DTM.
Stage 3 countries have declining birth rates, while Stage 5 countries have very low birth rates.
Compare the role of economic opportunities as a push vs. pull factor.
Lack of economic opportunities is a push factor, while the presence of economic opportunities is a pull factor.
Compare the population growth rate in Stage 2 vs. Stage 3 of the DTM.
Stage 2 has rapid population growth, while Stage 3 has slower population growth.
