The note proposes a methodology in which each of six offenses (rape, robbery, aggravated assault, burglary, larceny, and auto theft) will be examined to determine the extent to which it contributes to its respective overall rate. For each offense, a formula will be calculated that places the individual offense rate in the numerator and the total number of Part I offenses in the denominator. This will produce a figure that represents the occurrence of an offense relative to all offenses. For example, the burglary rate for official crime will be divided by the overall Part I official rate. With the exception of auto theft, each offense accounted for a strikingly similar proportion of the overall rate of survey or official crime. One table, 3 footnotes, and 19 references are supplied.
