CHOROPLETH MAP

Description:

  • A choropleth map is a type of thematic map in which a set of pre-defined areas is colored or patterned in proportion to a statistical variable that represents an aggregate summary of a geographic characteristic within each area, such as population density or per-capita income.
  • Choropleth maps provide an easy way to visualize how a variable varies across a geographic area or show the level of variability within a region.
  • Bubble Maps are good for comparing proportions over geographic regions without the issues caused by regional area size, as seen on Choropleth Maps.
  • A choropleth map brings together two datasets: spatial data representing a partition of geographic space into distinct districts, and statistical data representing a variable aggregated within each district.
  • Choropleth Map has X & Y axis.
  • It is a X vs Y graph.
    • X-axis represents one set of data.
    • Y-axis can represent single set of data.
