A choropleth map is a thematic map in which areas are shaded or patterned in proportion to the measurement of a statistical variable being displayed, such as population density or per-capita income. This type of map is particularly useful for visualizing how a measurement varies across a geographic area or for illustrating the level of variability within a region.

A thematic map is a type of map specifically designed to highlight a particular theme or subject area, such as population density, climate, or economic activities, by using various visual techniques like colors, symbols, and lines. Unlike general reference maps, thematic maps focus on specific data sets and are used to analyze spatial patterns and relationships related to the theme being represented.
