Number of reported offences adjusted down
The number of offences reported to the police has been reduced by 5.4 and 7 per cent, according to revised statistics on reported offences in the period 1993-2001. The changes are considerable for some types of offences, but the general picture is relatively unchanged.
New crime statistics from Statistics Norway on offences reported to the police
The statistics on offences reported to the police for the period 1993-2001 have been revised (cf. NOS Crime statistics 2001 ). As it was not possible to revise the statistics for 1992, 1993 is now the first year for which statistics on offences reported to the police are available from Statistics Norway. This revision will be followed up for later years, and new statistics for 2002-2004 will be published by the end of second quarter of 2005.
Theft and drug also dominate the new crime statistics
The revision (see textbox at the bottom) has been more comprehensive for crimes committed for personal profit and drug trafficking offences than for other types of offences. However, these offences still dominate the picture with regard to level and development of the total number of reported offences in the period 1993-2001. Crimes committed for personal profit constitute the largest group of offences reported to the police, and the level of these offences has remained relatively stable since the mid-1990s. Drug trafficking offences have had the highest increase in relative terms. During the last seven years of the reference period the number of such offences more than doubled.

The revision has had a greater impact on some types of offences than others. This is the case for some types of financial crimes, where the number of frauds reported to the police has decreased by 15-20 per cent and embezzlements by about 10 per cent.
The extent of the revision varies somewhat from year to year. The most comprehensive revisions were done for 1998, with the removal of more than 31 000 offences from the statistics. In addition, the importance of the revision varies for different types of offences. Compared with previously published statistics there has been a somewhat larger decrease - both in absolute numbers and as a percentage - for crimes than for summary offences (see figure). However, it is essentially a matter of a general reduction of the level - with an average annual reduction of 6.2 per cent for all offences reported to the police. For instance, in 2001, the distribution by group of offence in the revised statistics contains an almost identical share of the total as in the previously published statistics (see table).
|Offences reported to the police,|

|Group of offence||2001,|
|Other offences for profit||49.6||50.3|
|Offences of violence||5.8||5.7|
|Offences of narcotics||11.1||11.1|
|Damage to property||6.1||5.9|
|Work environment offences||0.2||0.2|
Background and method of revision, 1993-2001
The statistics are based on material from the police central register system STRASAK, which includes all offences registered by the police in the various police districts in Norway. The background for the revision is that some cases are transferred from one police district to another and thus the same offence is registered in both police districts. The revision is conducted by the use of information registered by the police themselves. When an offence has been registered several times, only the first registration is kept for statistical use.
The revision of the statistics involves the elimination of a considerable source of error. Some uncertainty is still tied to the accuracy of the revision, and the revision may have had a different impact for different years. After a thorough examination of different data and crime statistics, in addition to dialogue with Norwegian Police Data and Procurement Service (PDMT), Statistics Norway is of the opinion that the revision has entailed a considerable quality increase of the statistics on offences reported to the police.
Use of population to index has also changed
In calculations which include population figures (see tables), figures per 1 January in the statistical year will be used for the statistics on offences reported to the police (as distinct from previously, where per 31 December in the statistical year was used). This will become the practice for all future statistics including this one, also the ones involving previous years.
