UK Peace Index Methodology

The UKPI aims to move the conversation around violence from a narrow assessment of crime to a more holistic understanding of the root causes of violence, in order to identify the right policies needed to create a more peaceful and economically prosperous UK.

The UK Peace Index uses the same definition of peace as the Global Peace Index (GPI), whereby peace is "the absence of violence or the fear of violence".


The UKPI measures peace at the Local Authority (LA) level, with the population of these areas ranging from 35,000 to one million people. The index gauges peace according to the following five indicators.

The number of homicides per 100,000 people. This includes murder, manslaughter and infanticide.

The level of violent crime measures the number of “violent offences – with injury” per 100,000 people.

Weapons crime measures the number of offences per 100,000 people. This includes offences with firearms, knives, and other dangerous weapons.

The public disorder indicator is used as a proxy to measure perceptions of crime and fear of crime. The indicator measures violent disorder and harassment offences per 100,000 people.

The number of police officers per 100,000 people. This does not including Police Community Support Officers.

Given many of the areas measured have populations smaller than 100,000 people, the index is hyper sensitive to movements in most of the indicators. To gain a clearer indication of changes in peace over time, the UKPI uses a three year moving average to calculate the final score for each year. This means that the 2012 UKPI score is actually the average of data from 2010, 2011 and 2012.

Data compatibility

The data used in the UKPI is harmonised across England and Wales, however both Scotland and Northern Ireland have different definitions and collection systems for crime data. Therefore only areas in England and Wales can be directly compared.
