Which type of map is typically used to show variations between regions and countries?

• A. Choropleth map
• B. Dot map
• C. Bar chart
• D. Pie chart

Answer: (A)

Using color shading to represent data values across geographic areas is the idea behind a choropleth map. By assigning different colors or shades to regions or countries, it highlights how a variable varies from one place to another, making regional and national differences easy to compare at a glance. A dot map instead shows the location or density of individual points, which can illustrate distribution but doesn’t encode a uniform value for each region. Bar charts and pie charts are non-spatial diagrams that display values by category or proportion, not by location on a map.
