Population Density Flashcards
What is the difference between population density and distribution?
Population density tells us how many people there are per km2. Densely populated places have high population density and sparsely populated places have low population density.
Distribution the spread of people in an area. Distribution over the world is uneven.
What are some factors effecting population density and distribution?
4
Mountain areas are moist and bumpy/uneven.
Desert areas are hot and sandy.
However, areas with good resources and industry such as Western Europe are practical.
How do you calculate population density?
Total population / area km2
/ = divide
What are some positive reasons for low population density?
3
Low competition for jobs
Less pressure on education and healthcare
Available homes
What are some negative reasons for low population density?
3
Less taxes paid
Brain drain
Underemployment
