cartogram
a map that purposely distorts geographic space based on values of a theme (e.g., making the size of countries proportional to their population)
a cartogram...
sets area equal to attribute value
problem with cartograms
hard to read if not familiar with area
data for cartograms
can use anything above nominal data (derived and total)
cartograms work...
by juxtapositioning your mental map or familiar regions with an intentionally distorted version of those areas
cartograms only work if...
you know what the area should look like
cartograms (are) intentionally...
"provocative"-used to make a point visually, shock the audience into appreciating something
examples of things that can be depicted with a cartogram
population density
poverty
per capita consumption
poverty
per capita consumption
efficient representations
the base map and the thematic information are the same thing
why are cartograms sometimes easily dismissed?
they look "wrong" (even though they are supposed to)
disadvantages of cartograms
they look wrong
people are terrible at estimating areas (especially of complex shapes)
less effective for retrieving specific rates
tied to enumeration units
difficult to make! contiguous is harder than discontiguous

when are cartograms least effective?
for retrieving specific rates
when are cartograms most effective?
if large differences exist, especially if the highest rates go with the smallest areas
(contiguous/discontiguous) cartograms are harder to make
contiguous
