Background Information

What Does This Indicator Mean?
This indicator measures the rate of arrests for bias crimes by geographic region.   Referring to a specific time period and geographic region, this indicator measures the total number of arrests for bias crimes in the region divided by the population of the area and multiplied by 10,000.   Bias crimes are reported by the police department or sheriff’s office making the arrest, and not by the residence address of the arrestee, and so these rates will vary greatly as a result of political decisions within a region.  Further, the jurisdictions of law enforcement agencies overlap in many cases, skewing the city-level rates for this measure.  Finally, there has been much debate and confusion over the definition of a bias crime, thus compounding the difficulty in reporting.

For the purposes of this report, bias crimes are defined as in ORS 181.550(C) :

A bias crime is any crime “Motivated by prejudice based on the perceived race, color, religion, national origin, sexual orientation, marital status, political affiliation or beliefs, membership or activity in or on behalf of a labor organization or against a labor organization, physical or mental handicap, age, economic or social status or citizenship of the victim.”

Other Risk Factors or Indicators to Consider
Bias crime offenders are predominantly white males, while a disproportionately large share of victims are African-American though in absolute numbers whites are most often victims. Regions where racial tension or distinct social, racial or ethnic class divisions exist are most likely to experience high bias crime arrest rates.

Limitations of the Data
These data are reported by the individual law enforcement agencies within a region.  There is no means of verification that a particular agency has reported all arrests for a given time period, though these data are considered highly accurate and reliable.

These data most certainly under-report the number of bias crime arrests due to the reporting procedures and definitional issues mentioned above.  In addition, if an individual is arrested on more than one charge (e.g., DUII and vehicular manslaughter) only the most serious crime (manslaughter) is captured in the data collection system.  This is a national norm that began in the 1930’s and is considered standard practice as part of the Uniform Crime Reporting process nationwide.

Data Sources

  • Numbers of arrests are from the Oregon Law Enforcement Data System (LEDS) Oregon Uniform Crime Reporting Program

  • Population data are from Portland State University Center for Population Research and Census

Presentation and Discussion of the Data

The table below shows the numbers of arrests for crimes motivated by prejudice.  It gives the number of arrests in each city, as well as the total for Marion and Polk Counties.  For this indicator, it is particularly useful to know the actual number of arrests rather than just the rate, because the numbers are so small that rates are somewhat difficult to interpret.

The chart below shows the rate of bias crimes arrests per 10,000 people in Marion and Polk Counties.

Commentary

For all years from 1995 through 2001 the bias crime arrest rate in Marion County was higher than that found in Polk County. Much of this is due to the more racially, ethnically and socially diverse population found in Marion County. Quite simply, this diversity makes it possible for bias crimes to occur. 

Arrests for bias crimes have followed no discernible pattern over time.  Years with especially low rates (e.g., 1997) are both prefaced and followed by years with significantly higher rates.  This is largely a result of exceptionally low numbers of reported crimes, which makes the rates extremely volatile.  Marion County’s highest number of bias crime arrests recently occurred in 2000 when 12 arrests were reported, while Polk County had only one arrest for bias crimes in the past seven years.

The cities in Marion County where bias crimes arrests occur most frequently are Salem, Stayton, and Woodburn.  Most towns in Marion County reported no arrests for bias crimes in recent years.
