Crime Rates Calculation Essay, Research Paper

For illustration, the United States Census combines their population

informations with offense informations compiled from the FBI & # 8217 ; s Uniform Crime Reporting system ( UCR )

to bring forth offense rates. These rates are calculated with a invariable of 100,000

and are broken down by type of offense. As described by Sacco and Kennedy in The

Condemnable Event, the invariable in the above equation is designed so the offense rate

can be expressed per degree Celsius ( the invariable ) units of exposure. The choice of the

invariable is mostly arbitrary, but rates are traditionally expressed per 1,000

or per 100,000 units of exposure. It is, although, most of import to take a

value of degree Celsiuss so the ensuing rates will be meaningful to the reader. For illustration,

if you are ciphering offense rates for a town of 10,000 people, and you choose a

value of hundred * 10,000, the consequences will be expressed in footings of a population

greater than the town. Consequently, the consequences will non be meaningful to the

town occupants. On the other manus, if a value of 100 were chosen, a occupant

reading the rates would see how many people in a group of 100 would be probably to

be a victim of a given offense. In contrast to the invariable, which is arbitrary,

and the numerator which is provided by observations and studies, the denominator

must be carefully determined for each type of offense. To find this

denominator the mark population must be established. The mark population can

be defined as “ the population we want to speak about ” ( Mosteller,

Fienberg, and Rourke, 1983 ) . “ The usu

Al pattern is to utilize the sum

population shacking within the legal power in which the count of events has

taken topographic point ” ( Sacco and Kennedy, 1996 ) . Although, this method does non take

into history “ the demographic features of the population or the

empirical fact that different sections of the population are involved in

condemnable events with different degrees of frequence ” ( Sacco and Kennedy,

1996 ) . Sections of the population can be created by looking at transverse subdivisions of

age, sex and potency for victimization. Members of these sections may hold a

higher chance to being exposed to a peculiar offense so members of other

sections. For illustration, people who spend a big sum of clip outside their

places in the eventide may hold a higher potency of being a victim of a offense

such as aggravated assault. If the full population were used in the

denominator, the deliberate rate of aggravated assaults would be unnaturally

high for the general population and unnaturally low for the section of people

who go out in the eventide. In drumhead, when reexamining offense rates, the value of

the denominator should be considered when pulling decisions. If the

denominator reflects the size of the entire population shacking within the

measured legal power, decisions should reflect the possibility that subsets

of the population may be falsely included in the deliberate offense rate. If a

subset such as males aged 16 & # 8211 ; 30, were used in the computations, decisions

should see the subset of the population which may be excluded.
