population Flashcards
(23 cards)
How has the world population changed since 1800?
The world population has grown rapidly since 1800, mainly due to the Industrial Revolution and improvements in healthcare.
How are people distributed around the world?
People are unevenly spread, with more living in cities or near water, and fewer in deserts, mountains, and cold regions.
Why are some areas sparsely and some densely populated?
Some areas are densely populated because of good climate, resources, or jobs, while others are sparsely populated due to poor land, climate, or lack of resources.
Can you describe what a population pyramid shows?
A population pyramid shows the age and gender breakdown of a population.
Can you explain why birth rates and death rates might be higher or lower in different countries?
Birth rates and death rates can vary due to factors like healthcare, education, economy, and cultural beliefs.
Can you draw the shapes of a LIC and HIC country population pyramid?
LIC (Low-Income Country): Wide at the base and narrow at the top (more young people).
HIC (High-Income Country): More even or top-heavy (more older people).
Why do HIC and LIC countries have different population structures?
HIC countries often have lower birth rates, higher life expectancy, and more elderly people, while LIC countries tend to have high birth rates and lower life expectancy.
How and why do population structures change?
Population structures change due to changes in birth rates, death rates, migration, and improvements in healthcare and education.
How did China control their population?
China controlled their population through the one-child policy, which limited most families to having only one child.
How successful was the population policy, in china?
The one-child policy reduced China’s population growth but led to an ageing population and gender imbalances.
What is migration?
Migration is the movement of people from one place to another.
Why do people migrate? (push and pull factors)
People migrate because of push factors (like war, poverty, or lack of jobs) or pull factors (like better jobs, safety, or a better life).
