Overview of most common types of crime

There are many factors that make the comparison of data from different years difficult. For example changes in laws, the practice of how new cases are registered, the priorities of law enforcement agencies and the available resources. As well as the changes in how actively people report crimes to the police. This is why yearly victim surveys are an important supplement to the official data, although the data collected via the surveys and the official data are not directly comparable. For example an incident which the replicant considers a crime may not be so in the legal sense.
