World population is not evenly distributed. Some areas are densely populated-lots of people in a given area e.g. Manila Philippines 43,000 people per square kilometre. Or others are sparsely populated-area is one with very few people living there such as rural or remote areas. Greenland has an average of less than one person per kilometre.

32
Q

What are advantages to choropleth maps

A

Use of colour provides easy way to visualise how measurements vary
Allows us to draw conclusions quickly. Measurements vary across an area
Much easier to interpret than tables of data

33
Q

What are disadvantages to choropleth maps

A

Gives the impression that the area has the same value across it
Sharp boundaries gives the impression of abrupt change rather than merging
Grouping of intervals in categories need to be selected carefully
