Dot Map 1995 -- Dot Map 2000 -- Dot Map 2011
The maps presented here detail the locations of all residential burglaries in Portland, by year, from 1995 to 2011. This information can be used to identify areas in the city that experience higher numbers of this type of crime. While this information does say something about the relative dangers of different areas, it is important to remember that this sort of mapping does not control for underlying differences in both population and number of residences. Lloyd District, for example, consistently shows a low number of residential burglaries as compared to other geographic areas. Although this initially suggests that the Lloyd District is not as risky an area for residential burglaries, overall, on a per residence basis the actual risk could be greater than some other areas of the city because there are fewer residences in the Lloyd District.
Referencing the maps themselves, you will see in the video above that residential burglaries seem to be scattered throughout Portland neighborhoods. In some neighborhoods, especially in the maps of mid 1990’s, the dots seem to overwhelm the neighborhoods. It is important to remember that some neighborhoods can appear to have a large number of residential burglaries simply because there are large numbers of residences in the area. While this may create additional opportunity for residential crime, it does not necessarily indicate that any specific person residing in the area is at greater risk than in another area. In the creation of the incident maps, some incidences were not included in the map due to missing information in regard to location (1.1%).
Another important pattern seen within the maps is that the number of residential burglaries over time is decreasing (i.e. there are fewer “dots”). Between 1995 and 2011 residential burglary decreased by 43.1%. This decrease has not been distributed equally. For instance, Southwest Portland has experienced significant decreases in residential burglary and this can be observed with the decreasing number of “dots” in this area.
