ANNEX: Notes on statistics used in this bulletin |
| |
| Returns |
| |
| 11.1 The
statistical return from which most of the figures in this
bulletin are taken is a simple count of the numbers of
crimes and offences recorded and cleared up by the
police. Only returns from the eight Scottish home forces
are included in this bulletin. One return is made for
each council in Scotland and these are aggregated to give
a national total. Amendments (such as the deletion of
incidents found on investigation not to be criminal)
which arise after the end of the year are not
incorporated. |
| |
| 11.2 In 1993
information was collected for the first time from other
police forces, such as the British Transport Police etc.
This practice has been continued, but these figures have
not been included in the main body of the bulletin. Thus,
in addition to those crimes and offences referred to
throughout the bulletin there were, in total, 5,400
crimes and 6,500 offences recorded by the British
Transport Police, Ministry of Defence and UK Atomic
Energy Authority in 1998. The crime clear-up rate was 39
per cent and the miscellaneous offences rate was 37 per
cent. |
| |
| 11.3 The
figures included in the motor vehicle offences group do
not include stationary motor vehicle offences
dealt with by the issue of a fixed penalty ticket (some
395,000 offences, mostly parking, in 1998). However,
offences dealt with under the vehicle defect
rectification scheme and offences for which the
procurator fiscal offers a fixed penalty are included in
the figures. In addition to this, moving traffic
offences which are the subject of a police conditional
offer of a fixed penalty are also included, e.g.
speeding, traffic direction offences. |
| |
| Recording issues |
| |
| 11.4 In one
criminal incident, several crimes or offences may occur -
e.g. a house may be broken into and vandalised and the
occupants assaulted. In multiple offence incidents, all
the offences are counted rather than one for the incident
as a whole; that is, the counting system is offence based
rather than incident based. An offence may have more than
one victim - for example in robberies - and be committed
by more than one offender - e.g. some assaults and
housebreakings. (Note that for murder, attempted murder
and culpable homicide, the number of crimes recorded is
equal to the number of the victims). Thus the statistics
in this bulletin are not directly comparable with
statistics on action taken against offenders, as one
offence may lead to several persons being charged.
Equally, an offender may be charged with several
offences. The statistics for recorded number of crimes
given in this bulletin are also not directly comparable
with statistics collected in England and Wales for the
recorded number of notifiable offences. This is mainly
due to differences in the counting rules ; for notifiable
offences the counting system is, wherever possible victim
based rather than offence based. The Home Office
introduced new counting rules for notifiable offences,
and expanded their coverage on 1 April 1998. |
| |
| 11.5 In
Scotland, assault is a common law offence. In order to
distinguish between serious and minor assaults (termed
petty assault in the classification) police forces use a
common definition of what is a serious assault. Although
the definition did not change between 1980 and 1989 it
became clear that over the years forces had adopted
different interpretations. The definition of serious
assault was amended at the start of 1990 to improve
consistency between forces in coding assaults into
serious and petty assault. The result of the revision to
the definition has been much closer agreement on the
interpretation of the definition of serious assault
across forces, but it has resulted in a reduction in the
number of assaults recorded as serious. It is estimated
that the number of serious assaults that would have been
recorded in 1989, using the revised definition, is some
1,150 fewer than that actually recorded, with a
corresponding rise in petty assaults. In the tables in
this bulletin, the number of recorded serious assaults
etc. (which include cases of murder, culpable homicide
and attempted murder) and petty assaults have not been
adjusted. The table below gives the number of serious
assaults etc. and petty assaults recorded in 1989 and
1990 together with adjusted figures for 1989. |
| |
| |
| 11.6
Attempts to commit an offence are included in the
statistics, in general in the same group as the
substantive offence. |
| |
| Reporting practice |
| |
| 11.7 These
statistics do not of course reveal the incidence of all
crime committed. Not all incidents are reported to the
police. The British Crime Survey (BCS) Scotland, a survey
of crime victims, suggested that in Scotland victims
reported 44 per cent of incidents to the police in 1987,
up from 38 per cent in 1981. This increased to 55 per
cent in 1992 before falling back to 50 per cent in 1995.
The two reasons most commonly given by victims for not
reporting to the police were that the incident was
considered by them to be too trivial or that the police
could not have taken any action in any case. |
| |
| 11.8 Many
offences, for example, speeding or possession of drugs,
have no victim other than perhaps the perpetrator and are
discovered and recorded as a result of police activity
rather than by being reported to the police by the
public. Hence the numbers of such offences recorded are
mainly determined by the strength and deployment of the
police forces. |
| |
| 11.9
Variations in police recording practice can also occur
between areas over time. It is known, for example, that
the introduction of computerised crime logging systems
has resulted in improved recording of minor incidents in
Scotland since 1975, and as such systems come to be more
widely used and improved such effects will continue to
occur. |
| |
| Revision to recorded crime series :
offending while on bail |
| |
| 11.10
Section 2 of the Criminal Justice (Scotland)
Act 1995, which came into effect on 31 March 1996,
amended the Bail etc. (Scotland) Act 1980 provisions
relating to breach of bail conditions. Consolidation
under the Criminal Procedure (Scotland) Act 1995
subsequently took place with the provisions relating to
breach of bail conditions contained in section 27 of this
Act. |
| |
| 11.11 The
revisions made by the Criminal Justice (Scotland) Act
1995 included one change that impacted on the recording
of crimes by the police. Under the 1980 Act,
breaching the bail condition that no further offences
would be committed while on bail was treated as an
offence in its own right. The 1995 Act changed this;
breaching this condition ceased to be a separate offence.
Under the new provisions (which have applied since
April 1996), if an accused commits a further offence
while on bail then it is taken into account in sentencing
for that offence. The court is now required, in
determining sentence, to have regard to the fact that the
offence was committed while on bail and may impose a more
severe sentence than it would otherwise have done for the
conviction. The new provisions under the Criminal Justice
(Scotland) Act 1995 apply to any bail order made on or
after 31 March 1996. |
| |
| 11.12 The
recorded crime series was revised to remove all crimes of
"offending while on bail" from the historical
data (1983-1995) to enable comparisons over time to be
made. Full details of the changes can be found in the
statistical bulletin "Recording of Offending
while on Bail, Scotland", CrJ/1997/1. |
| |
| Crimes and offences cleared up |
| |
| 11.13 The
definition of cleared up is noted below. This
definition came into force with effect from 1 April 1996. |
| |
| A crime
or offence is regarded as cleared up where these exists a
sufficiency of evidence under Scots law, to justify
consideration of criminal |
| proceedings
notwithstanding that a report is not submitted to the
procurator fiscal because either |
| |
| (i) by
standing agreement with the procurator fiscal, the police
warn the |
| accused
due to the minor nature of the offence, or |
| |
| (ii)
reporting is inappropriate due to the non-age of the
accused, death of |
| the
accused or other similar circumstances. |
| |
| For some
types of crime or offence the case is cleared up
immediately because the offender is caught in the act,
e.g. motoring offences. In Scots law, the confession of
an accused person to a crime would not in general be
sufficient to allow a prosecution to be taken as
corroborative evidence is required. Thus, a case cannot
be regarded as "cleared up" on the basis of a
confession alone. In some cases there is sufficient
evidence but a prosecution cannot be brought, for
example, because the accused has left the country. In
such cases, the offender is said to have been traced and
the crime is regarded as cleared up. The other terms in
the definition describe the various actions that must be
taken by the police against offenders. |
| |
| 11.14
Certain motor vehicle offences are not always recorded in
cases where police forces are unable to clear-up the
offence (e.g. speeding offences where the driver is
untraceable). Clear-up rates for motor vehicle offences
in these circumstances are artificial. Thus, clear-up rates
for the motor vehicle group and clear-up rates for
Total Offences and Total Crimes and Offences (which
include motor vehicle offences) are not included in the
bulletin. However, the number of motor vehicle
offences cleared up is still included. |
| |
| 11.15
Clear-up rates in excess of 100 per cent can arise where
offences recorded in one year are cleared up during the
following year. |
| |
| Classification |
| |
| 11.16
Contraventions of Scottish criminal law are divided for
statistical purposes into crimes and offences. The term
"crime" is generally used for the more
serious criminal acts; the less serious are termed
"offences", although the term
"offence" may also be used in relation to
serious breaches of criminal law. The distinction is made
only for working purposes and the "seriousness"
of the offence is generally related to the maximum
sentence that can be imposed. |
| |
| 11.17 The
detailed classification of crimes and offences used by
The Scottish Office to collect criminal statistics
contains about 350 codes. These are grouped in the
bulletin as shown below. |
| |
| 11.18 The
following symbols are used throughout the tables in this
bulletin |
