Choropleth Map
Choropleth maps are
thematic maps in which
areal units are shaded in
proportion to measurement
of variable (e.g. population
density)

Choropleth Map
 With Layer Properties opened, go to Symbology and then select:
Quantities > Field (POP05_SQMI) > OK
 A choropleth map showing population density (2005) per county
within Washington State is shown

Calculating new variables
 Examine Table Attributes of
your created shapefile
 Let us say we are interested to
see the spatial distribution of
proportion of blacks per
county in Washington State
 We can create a new
attribute(variable) (say,
variable name, pblack) for this
by using the formula:
pblack=black/pop2000

 With the Add Field window
open, fill-out variable
specifics (name = pblack, type
= double)
 Right click the new variable,
pblack, and click Field
Calculator
 With the Field Calculator
window open, calculate the
values (see illustration)

EXERCISE ALERT!!!
1. Make a choropleth map using the
new variable, pblack.
2. Try exploring other map types, e.g.
population dot maps
 With our desired map made, we can proceed to create our map
layout
 Go to View > Layout View
 In the Layout View, we can add the classic elements of maps,
e.g. Title, Legend, Scale, Direction
 We can save the map and convert it into image file by going to
File > Export Map >
