What is a thematic map?
A thematic map is also called a special-purpose, single-topic, or statistical map. A thematic map focuses on the spatial variability of a specific distribution or theme (such as population density or average annual income), whereas a reference map focuses on the location and names of features.

What is the difference between quantitative and qualitative map?
Maps can depict two kinds of data. Qualitative map data is in the form of a quality and expresses the presence or absence of the subject on a map, like the kind of vegetation present occupying a region.

Paper has many advantages as a medium, such as ease of transport, low cost of production, and no requirement of specialized hardware or software to view.
Why is a cartogram not a map?
Because a cartogram does not depict geographic space, but rather changes the size of objects depending on a certain attribute, a cartogram is not a true map. Cartograms vary on their degree in which geographic space is changed; some appear very similar to a map, however some look nothing like a map at all.

Why is it called a thematic map?

¿Qué es un cartograma?
Un cartograma es un mapa o diagrama que muestra datos de cantidad asociados a sus respectivas áreas, mediante la modificación de los tamaños de las unidades de enumeración.
¿Qué es un cartograma con contigüidad?
Los cartogramas con contigüidad son aquellos en los cuales las unidades internas son adyacentes entre sí, pareciéndose en gran medida a un mapa convencional. La conservación de la contigüidad permite asociar la imagen distorsionada con el espacio geográfico que se conoce.
¿Por qué el lector de un cartograma puede ver una imagen distorsionada?
El lector de un cartograma puede ver una imagen distorsionada, que poco se acerca a los mapas que está acostumbrado a ver, ya que con la aplicación de esta técnica se pierden las relaciones de contigüidad y de orientación.
¿Cuáles son las ventajas de los cartogramas?
La principal ventaja de los cartogramas es que su utilización resulta impactante, despertando la curiosidad del lector en lo que allí se encuentra representado. Este impacto favorece la comunicación cartográfica.
