Understanding Choropleth Maps

Study Notes

A choropleth map is a type of map that uses shading to show data on a geographic area, with darker shades indicating higher values.
Choropleth maps can be used at different scales, including global, national, and local.
The map of London shows that the darker blue shades indicate areas with more people living in that part of the city.
A choropleth map showing life expectancy for men in England reveals that the southern regions have a higher life expectancy, while the northern regions have a lower life expectancy.
The advantages of choropleth maps include their ease of reading, ability to be used at different scales, and adaptability of the key to reflect different values.
One disadvantage of choropleth maps is that they can make it seem like the entire area has the same value, without allowing for variation within that area.
Another disadvantage is that changes along the boundaries of the areas being measured can be abrupt, rather than gradual.
A third disadvantage is that if all areas are colored in the same shade with different hues, it can be difficult to distinguish between them.
A choropleth map of rent prices in London boroughs shows that the closer to the center of the city, the higher the rent prices.
One advantage of using choropleth maps is that they make it easy to spot patterns in the data.
One problem with choropleth maps is that they do not show variation within each area, which can make the data misleading.
