Designation for Northern Ireland motoring offence statistics

Dear Senior Statistician,

CONFIRMATION OF NATIONAL STATISTICS DESIGNATION FOR NORTHERN IRELAND MOTORING OFFENCE STATISTICS

We have reviewed the actions that your team has taken to address the requirements in Assessment Report number 347: Motoring Offence Statistics.

On behalf of the Board of the UK Statistics Authority, I am pleased to confirm the designation of National Statistics for the Motoring Offence Statistics, produced by Police Service of Northern
Ireland. The statistics provide relevant, trusted information about motoring offences in Northern Ireland, with a good overview of the main trends. They enable users to better understand road
safety in Northern Ireland and to develop policies that aim to improve it.

During the course of the assessment the team responsible for producing the statistics showed great commitment to the improvement of these statistics. We are really pleased by the enthusiastic and thorough approach the team has taken to meeting the requirements from the Assessment Report. We anticipate that the addition of new data and improvements to the presentation of the published statistics will add value for users and give them greater insight into the geographic distribution of motoring offences and into trends.

We have included more detail about our judgment in an annex to this letter. I, or my team, would be happy to talk you or your colleagues through any aspects of this letter or Code compliance more generally.

National Statistics status means that official statistics meet the highest standards of trustworthiness, quality and value and is something to be celebrated. We invite you to include a statement alongside the statistics which reflects the National Statistics status.

I am copying this letter to Siobhan Carey Chief Statiscian NISRA; Ruth Fulton Head of NISRA Statistcial Branch, Chief Constable PSNI and Stephen Donnely NISRA.

Your sincerely
Ed Humpherson
Director General for Regulation

Police Recorded Injury Road Traffic Collisions and Casualties Northern Ireland statistics

Dear Senior Statistician

POLICE RECORDED INJURY ROAD TRAFFIC COLLISIONS AND CASUALTIES STATISTICS FOR NORTHERN IRELAND

I am writing to you following our review of Police Service Northern Ireland (PSNI) Police Recorded Injury Road Traffic Collisions and Casualties Northern Ireland statistics against the Code of Practice for Statistics. The statistics have been considered as part of a wider review of the devolved nations’ road safety statistics, following our compliance check of Road Accidents and Safety statistics for Great Britain produced by the Department for Transport. The statistics were reviewed against the three pillars of the Code: trustworthiness, quality and value. These are crucial in ensuring that the statistics serve the public good and support the police to implement and monitor road safety initiatives in Northern Ireland.

I am pleased to confirm that these statistics should continue to be designated as National Statistics. We found several positive examples in the way that PSNI produces and presents these statistics. We also found many positive examples of PSNI seeking to enhance the quality of the data. For example:

  • We commend the team for its thorough and robust quality assurance processes. Dedicated administrative staff carry out validation checks on incoming data. These checks are supplemented by a range of quality assurance checks carried out by the lead statistician, including following up any unusual entries with the original officer. The team is able to identify the number of records that are still to be submitted and works with police officers and the Occurrence Case Management Team to obtain these. The producer team cross-checks its figures with alternative data sources and the team’s expert subject knowledge allows it to identify and investigate patterns and outliers.
  • In order to further improve quality management, the team recently reviewed its analytical code and process. This has resulted in a streamlined, well-documented process and fewer manual steps, which has reduced the risk of error.
  • The statistics are well presented using figures and tables. The accompanying user guide explains the data collection process and the risks to data quality during the recording process in a manner that effectively highlights the strengths and limitations of the data.

We have identified several areas where we consider that improvements could further enhance the public value of the statistics:

  • We recommend that the team establish a stronger working partnership with other producer teams in the devolved administrations who use the STATS19 collection series. Greater collaboration could lead to greater input and influence during the STATS19 review process and ensure that the issues that concern devolved administrations are considered.
  • In line with the recommendations in our recent assessment of PSNI Motoring Offence Statistics, we encourage the team to consider enhancing its statistical commentary to provide information on related statistics, most notably the Motoring Offence Statistics and road safety statistics produced by the Department for Infrastructure. This would aid users in understanding changes in the numbers of road traffic collisions over time. We also encourage the team to publish a development plan for the statistics – this will be most important should there be any changes to the data collection process following the outcome of the STATS19 review.
  • Whilst the team has produced a comprehensive report on under-reporting of road traffic collisions within the accompanying user guide, we encourage the team to integrate some of the findings into the main statistical publication. Specifically, including the comparisons of rates of road traffic collisions with other data sources will give users a much clearer picture of the extent of under-reporting.
  • With official statistics producers in other devolved administrations having either moved to or considering new data recording systems, such as CRASH, to produce road traffic collision statistics, we encourage PSNI to keep under review the advantages and limitations of STATS19 and other methods of recording these data.

Our Travel, Transport and Tourism team will continue to engage with you and your team in the coming months to follow up on areas that have been highlighted for improvement. We would like to thank the team for their engagement and cooperation throughout the review process.

I am copying this letter to Siobhan Carey, Chief Executive NISRA; Stephen Donnelly, Senior Principal Statistician NISRA; Ruth Fulton, Head of NISRA Statistical Support and Business Planning; and Norma Broomfield, NISRA Statistical Support Branch.

Yours sincerely

Assessment of PSNI Motoring Offence Statistics

Dear Senior Statistician

ASSESSMENT OF THE MOTORING OFFENCE STATISTICS FOR NORTHERN IRELAND

Thank you for inviting us to assess the Motoring Offence Statistics, produced by Police Service of Northern Ireland, against the Code of Practice for Statistics. We have completed our assessment and have today published our Assessment Report. I am grateful for the positive contribution and engagement of your team throughout the assessment process.

During our assessment, we found that the statistics provide relevant, trusted information about motoring offences in Northern Ireland, with a good overview of the main trends. They enable users to better understand road safety in Northern Ireland and to develop policies that aim to improve it. Our user engagement confirmed that users are happy with the published statistics: users of the statistics are also extremely complimentary about the statistics team and how it engages with questions and requests for additional analysis.

We also commend the statistics team for its ongoing commitment to producing high quality statistics. The team has a strong working relationship with its data suppliers. This allows the team to easily request changes to the data it receives, which in turn allows the team to continue to provide analysis on policy changes or when new areas of interest arise.

While we are impressed by the statistics that PSNI produces, we have identified several ways that the statistics should be strengthened further, to ensure that they fulfil the expectations of the Code. Our four Requirements ask your statistics team to focus on: pre-emptively meeting the additional data and analysis needs of those using the statistics; increasing the value and insight offered by the statistics through linking to other statistics that could help explain trends; extending the reach of the statistics by trying to broaden their user engagement; and improving transparency around the team’s plans for developing the statistics, so that users can better shape this work.

We judge that the Motoring Offence Statistics can be designated as new National Statistics once these Requirements have been met. You are due to report back to us in February 2020, outlining how you have addressed the Requirements. Please feel free to discuss any aspect of this with me or my team at any time.

Your sincerely

Ed Humpherson
Director General for Regulation
