Exhibit 1 organizes and summarizes the
discussion of hot spot analysis so far and
introduces what is to come. The first column
describes the geographic concentration
at various levels of interest. The
second column describes the basic pattern
formed by hot spots at each level. The
third column lists the geometric dimension
to be used on a crime map to depict
each type of hot spot. Place theories suggest
maps with dots, street theories suggest
maps that emphasize lines, and area
theories suggest the use of polygons on
maps. Repeat victimization theories do not
directly correspond to a single dimension
or level. They can be depicted on maps by
dots, lines, or polygons. The last three
columns highlight points discussed next.
Examined are four types of hot spots—
places, victims, streets, and areas.
