Changes to DfT statistics publications due to coronavirus (COVID-19)

The changes outlined on the web page are no longer current. For the latest information, see forthcoming publications.

We are adapting DfT’s regular statistical production in response to the coronavirus (COVID-19) pandemic. Wherever the coronavirus has an effect on the quality of our statistics, for example in the form of delays, lower accuracy or reductions in the level of breakdowns we are able to publish, this will be reflected in the data quality statement for each statistical release.

In some cases, the production of a data series may need to be suspended or delayed. Decisions are made on a case-by-case basis, guided by the 3 pillars of the Code of Practice for Statistics —Trustworthiness, Quality and Value. These decisions will be underpinned by the Office for Statistics Regulation’s guidance on changes to statistical outputs during the coronavirus outbreak. We remain committed to providing the best and most accurate information we can, and our priority will be to minimise the impact of any discontinuity on the longer-term evidence base. We will update this page with any future developments.

As the demand increases for statistics and data to measure the impact of the coronavirus pandemic, we will take into account the challenges and additional pressures our data suppliers are facing by focussing efforts on priority analysis and statistics.

Some of the data used in DfT statistical publications is part of the Single Data List, which covers all data returns that central government requires from local authorities. We are mindful of the additional pressures local authorities are facing as a result of the coronavirus pandemic. We have, therefore, reviewed the priority of local authority statistical collections and considered whether collections should be minimised, deferred or cancelled to reduce the burden on authorities. This is detailed in the table below. We will keep these changes under review and consider whether a further delay or alternative plan is required.

Other considerations can contribute to delays to the original publication schedule. Priority work on the DfT’s response to the coronavirus pandemic has resulted in resourcing pressures leading to some publications being postponed. Other changes to the schedule might be caused by data collections issues, where data suppliers are unable to provide data or when data collection cannot feasibly take place. These are also indicated in the table below.
