Choropleth maps have some limitations:

No matter what the spatial scale, these maps represent only the average value for each of the units.
Mean values are generalisations; they conceal spatial variations within the area they represent.
The larger the spatial unit used in the plotting of data, the greater the degree of generalisation.
Where neighbouring spatial units have different densities, the map gives the impression of a sudden break at the boundary between them.
