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

Easy Mapping Techniques Using ArcGIS|Adding Fields and
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

Easy Mapping Techniques Using ArcGIS|Map Layout
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 >
