Polk County, Iowa Crime Statistics and Crime Data

About the Crime Data: The crime index process divides an area population into the number of reported crimes within that area to yield a ratio of crimes per 100,000 people. The use of indexing enables us to compare the crime rate between different kinds of areas and communities. In recording the number of crimes to create the crime index, crimes and population are only counted once; because of this, the reported crimes and population of a county may be less than that of a city within that county. Petty larceny below $50 and arson are not included in these statistics.

While indexing is useful in determining relative risk, it does not represent the actual risk, because the number of crimes is only compared to the estimated number of permanent residents of the jurisdiction where the crime occurred. For example, while the crime rate in the nation's Capital is very high, the actual number of people in the Capital at any time is likely to be three times the number of residents. This situation carries over to crime rates in jurisdictions that primarily operate as industrial and resort areas.

When we can, we provide a more complete breakdown of types of crime than is normally available. (Not every jurisdiction submits crime data in the format that the FBI requests.) In Normal Text are the standard categories of crime. In Italicized Text are subcategories of the standard categories. In Bold Text are sums of Violent, Property and Total Crime. Except in States with a low population, we are not providing statistics for jurisdictions with a population of less than 10,000 people. Crimes associated with jurisdictions that do not have a permanent population, such as colleges and judicial departments are not included in the statistics.

For crimes associated with students in the United States start with School-associated violent deaths and number of homicides and suicides of youth ages 5–19, by location: 1992–2002.
