A Demographic Analysis gives information about an areas population in relation to the ages, race, gender, income, ethnic origin, and level of education. The demographic analysis is mostly used for strategic assessment and long term planning for law enforcement. The reason for analyzing this type of information is to predict by the indicators of the population the threat of criminal activity within an area. If it is known that the male population between the ages of 18 to 23 with an income of $30,000 or more are more likely to participate in drag racing and the population of an area just increased with these factors than the potential for accidents due to road racing will probably increase. By using the demographic analysis, the law enforcement agency can save lives and decrease the criminal activity before it is to late.
An Event Flow Analysis depicts events listed chronology. Most of the time the event flow analysis is used for one particular criminal activity. This type of analysis can show how a criminal activity is leading up to (or leading away from) another activity. This kind of analysis can be done as events unfold, because you have to wait for the events to occur, or you can demonstrate the events that have already occurred and conclude that the probability of another occurrence is likely.
A Telephone Record Analysis is an analysis that is built by collecting of telephone bills or nonaudio wire receipts. This type of analysis is a good way to find out what organizations or individuals a criminal is calling and can identify conspirators or other individuals that are that the criminal is either selling illegal merchandise to or buying it from. During this type of analysis the analyst can collect long-distance bills that have the numbered dialed on them or use a dialed number recorder (DNR), which will have every number that is dialed out on a particular line. This type of analysis has an excellent use against a phone-based criminal activity like a gambling or bookie ring.
