What is the difference between population distribution and population density?

The purpose of this low stakes is to show how the distribution of people in a country differs from its population density. . Complete the table. Population distribution computed as the country’s share of total population is country population divided by total population of all countries in this list multiplied by 100. Population density is computed as country population divided by country area in square kilometers

1) What is the difference between population distribution and population density?
2) Find one example of a country in the list above with a large population but a relatively low population density.
3)Find one example of a country in the list above with a small population but a relatively high population density.
4) Does a large total population necessarily lead to a high population density? Why not?

5) Describe one problem with only using population density to determine how crowded the population of a country is.
