Standardizing the Display of IBR Data: Property Variables

Frequencies and Rate of Missing Data for Property Variables

Frequencies at a Glance

Most Common Property Loss Type? Stolen (59.9%)
Rate of Missing for Property Description? 4.8% for required offenses

Frequencies of Reported Property Variables

The 1999 NIBRS file contains 2,401,899 types of property loss in 18 states.  All of the possible variable types occur in the file.  The frequencies for property loss types and property descriptions are presented below.  Since there are incidents with multiple property loss types, the number will be higher than the total number of incidents.

Almost 5% of the items involved in property offenses are coded with a loss type of "none"; these probably correlate to attempted offenses.

The most frequently reported category of property is other at 19.6%.  Automobiles are the second most frequently reported property type at 8.9%.

When property value is separated into categories, we see that 81% of the property with a valid entry is valued at $500 or less.  Almost 45% of the property with a valid entry is valued at under $50.

Surprisingly, 91 property items were valued at over $1,000,000.  Six property items were valued at over $100 million, with the most expensive item listed as "other" and valued at $245 million.  Two computer hard/software items were listed for over $150 million, and two property items were described as tools and listed at $100 million.

Although possible, it seems unlikely that bicycles would be valued over $1 million.  This record should be checked.
