In January 2014, UK Statistics Authority found that the statistics based on police recorded crime data did not meet the required standard for designation as National Statistics. Police recorded crime is not currently considered a reliable measure of trends in crime for most crime types.
. These increases need to be seen in the context of the focus on the quality of crime recording by the police in recent years. This follows inspections of forces by Her Majesty's Inspectorate of Constabulary (HMIC), the Public Administration Select Committee inquiry into crime statistics, and the UK Statistics Authority's decision to remove the National Statistics designation from police recorded crime statistics in 2014.
The police recorded nearly 5 million offences in the year ending March 2017, which represented an annual rise of 10%; this increase is likely to reflect a range of factors, which vary by crime type, including continuing improvements to recording processes and practices, expanded offence coverage and also genuine increases in some crime types.
