The statistics on offences known to the police describe the regional distribution of offences and activities of the police. The statistics contain data on the types and numbers of detected offences. In addition, they examine the numbers of offences investigated and solved by the police, proportions of solved offences by type of offence and cases where reporting has been found ungrounded. In respect of solved offences the statistics also contain data on the suspected persons and their ages. The statistics further include data on family violence and on municipal parking control and on certain tasks performed by the police, such as investigations of suicide cases, traffic accidents with deer animals and causes of fire. Data on customs offences, such as those prescribed in the Customs Act and other offences decreed to be handled as customs offences are also published in connection with these statistics.
