The links provide details such as coverage, and strength and limitations of the data, and also the processes used to produce and publish the datasets behind the statistics quoted in the progress report.

Whilst most of the narrative in the Wellbeing of Wales report is drawn from national indicators, some of the contextual data is from other official statistics or other statistics and factual statements related to specific policies or programmes, where we have considered it relevant to the overall narrative.

The data not collected through official statistics sources are used in the Wellbeing for Wales report for context, but we cannot always provide assurance about data quality. As the data in the progress report have been sourced from a variety of datasets, the level of quality information available will differ in each case. Where the original data sources have detailed quality reports, we have provided links to those reports. Where quality reports do not exist for a source, additional information, where available, has been included in this document.

The quality report for the National Indicators, which can be found on the Wellbeing of Wales webpages, contains information about the quality of the data used for the indicators. Therefore, those data sources are not covered in this document.

Air quality average concentration indicators (Welsh Government)

Air Quality Indicators data on StatsWales

Each year the UK Government’s Pollution Climate Mapping (PCM) model calculates average pollutant concentrations for each square kilometre of the UK. The model is calibrated against measurements taken from the UK’s national air quality monitoring network.

The Welsh Government has used this published data to assign a concentration of NO2, PM2.5 and PM10 to each residential dwelling in Wales based on which square kilometre of Wales it sits in.

Please see the Methodology section of Modelled background pollution data (Department for Environment Food & Rural Affairs) for quality and methodology information.

Air Quality Management Areas (Welsh Government)

Section 82 of the Environment Act 1995 (legislation.gov.uk) requires every local authority to review the present and likely future air quality within its area. Section 83 requires local authorities to designate an air quality management area (AQMA) when a national air quality objective is not being achieved, or is not likely to be achieved. Section 84 then requires a local authority to develop an action plan for the AQMA.

The linked table summarises the local authorities across Wales that have declared active AQMAs.

The Department for Environment, Food and Rural Affairs and the Devolved Administrations have provided a range of tools to assist local authorities with the Air Quality Review and Assessment process. These tools are all available online and can be downloaded: Air Quality Assessment (Department for Environment Food & Rural Affairs).

Examination results (Welsh Government)

Due to the cancellation of the normal examination period in 2019/20 and ongoing disruption to schools as a result of the coronavirus (COVID-19) pandemic, the Welsh Government has decided not to calculate or publish performance measures for 2019/20 or 2020/21, for both Year 11 and sixth form cohorts.

Following the cancelation of public examinations, all qualifications that would have been sat as examinations in the 2019/20 summer term have been replaced with the best of either the centre assessed grade (CAG) or the standardised grade calculated by the WJEC. Centre assessed grades were decided using the teacher’s best professional estimate of what the pupil would achieve had they been able to sit an exam. Teachers may use any criteria they wish when estimating grades including (but not limited to) completed course work, mock exams or previous academic achievement.

These data are published as National Statistics. Please see the key quality information section of Examination results, September 2019 to August 2020.

National rough sleeper count (Welsh Government)

National rough sleeper count

A national rough sleeper monitoring exercise was carried out by local authorities, in partnership with other local agencies to gauge the extent of rough sleeping across Wales. It consisted of a two week information gathering exercise in October 2019 (Phase 1), followed by a one night snapshot count on 7th November 2019 (Phase 2). The November 2019 count is essentially a snapshot estimate and can only provide a very broad indication of rough sleeping levels on the night of the count. A range of factors can impact on single-night counts of rough sleepers, including location, timing and weather. These figures are separate from statutory homelessness statistics which provide information on the number of households applying to local authorities for housing assistance under the Housing Act (Wales) 2014 because they are homeless or threatened with homelessness.

School Sport Survey (Sport Wales)

The School Sport Survey, 2018 (Sport Wales) is an online survey of pupils’ sport participation and school provision of Physical Education [PE] and sport. The latest survey took place in the summer term of 2018 from 16 April to 24 July.

Pupils completed a questionnaire on their participation and attitudes towards PE and sport. A member of staff from each school was asked to complete a questionnaire on PE and sports provision at their school. This is usually completed by the PE coordinator in primary schools or the head of PE in secondary schools. The data from this survey enables Sport Wales and its partners to strategically monitor trends in sport participation, covering both extracurricular and community sport. The survey also allows for the tracking of PE provision in schools, as well as teachers’ and pupils’ attitudes to PE and sport.

The statistics presented in this paper and in the accompanying national set of data tables focus on pupils in mainstream schools in Years 3 to 11. In the 2017/18 survey, 118,893 Year 3 to 11 pupils took part in the survey and 1,055 teachers completed a School Sport Survey provision questionnaire.

Vaccine update in children in Wales (Public Health Wales)

National immunisation uptake data (Public Health Wales)

Vaccination uptake data are provided by the Public Health Wales national COVER scheme. These data are not published as official statistics. This surveillance scheme, which is run by the Public Health Wales Vaccine Preventable Disease Programme (VPDP) and Communicable Disease Surveillance Centre (CDSC), calculates vaccine coverage using data from National Community Child Health Database (NCCHD). The NCCHD is maintained by NHS Wales Information Service (NWIS) and is comprised of extracted records of all health board Child Health office database across Wales. The NCCHD is refreshed on a quarterly basis.

The denominator of uptake calculations used in the annual COVER report is the number of children registered with Child Health offices who reached key measurement birthdays during the April to march year and were living and resident in Welsh health boards as at the end of this period. Children are deemed to be vaccinated by a measurement age if they have a documented vaccination date in their child health record, which is before the relevant birthday.

Data quality within the NCCHD may diminish for older children who receive less frequent contact from health care professionals, and whose child health records may be updated less frequently.

Welsh sport activity levels during the coronavirus pandemic (Sport Wales)

Welsh sport activity Levels during the Coronavirus Pandemic (Sport Wales)

Savanta ComRes interviewed 1,004 Welsh adults (16+) online from 13 August to 16 August 2021. Data were weighted to be demographically representative of Welsh adults by gender, age, region, social grade, and the estimated households with children under 16. Savanta ComRes is a member of the British Polling Council and abides by its rules.

The survey was conducted online using Savanta’s internal participant panels. The survey is offered to all those on the panel who live in Wales and are aged between 16 and 99 years old.

The panel is updated continuously with new members whilst inactive or poor-quality members are removed on a regular basis.

As the survey is “opt-in” (i.e. panel members choose to take part) participants are not obliged to complete the survey once starting and are able to drop out at any point.

As the survey is completed on a quarterly basis respondents who completed the survey in the previous quarter are not excluded as an adequate amount of time has passed between surveys to prevent any issues with the data collected.
