Which term represents a map that shows the base map with additional data such as economic information layered on it?

• A. Base map
• B. Choropleth map
• C. Thematic map
• D. Economic map

Answer: (C)

A map that layers economic information on top of a geographic base is a thematic map. The central idea is to emphasize a specific topic or theme—here, economic data—while using the base map as the spatial framework. Thematic maps focus on how that theme varies across space, which is exactly what happens when you attach economic data to a base map. A choropleth map is a common way to present a thematic map, coloring regions by value, but it’s a specific type within the broader category. The base map alone has no theme, and “economic map” isn’t a standard cartographic term, so the best, most descriptive label for this concept is thematic map.
