The National Survey for Wales is a study run by Office for National Statistics on behalf of the Welsh Government. The study gathers information on many topics including health, schools, sports, arts and culture.

Frequently asked questions

Why is this study important?

By taking part in this study, the Welsh Government will be able to produce statistics that will give a better understanding of life across the whole of Wales. The results will be used by the Welsh Government to make decisions that affect everyone. Topics include health, schools, sport, arts and culture.

Why should I take part?

Whatever your circumstances, they are relevant to this study. Obtaining information from as many selected households as possible is the only way the Welsh Government can get a complete and accurate picture of Wales’ circumstances. By taking part, you ensure that your experiences and circumstances become an important part of the bigger picture of life in Wales today and help to shape policies that affect services in Wales.

What is involved?

An Office for National Statistics (ONS) interviewer will contact you to arrange a suitable time to conduct the interview. During the interview one adult member of the household will be selected at random to complete the study. This person will then be asked questions on a range of topics, such as health, wellbeing, education and the Welsh language.

Can I be interviewed in Welsh?

Yes. If you would like to be interviewed in Welsh, please tell the interviewer when they visit, or contact the freephone number +44 (0)800 496 2119 to arrange this in advance.

Who is carrying out the study?

The study is being conducted by Office for National Statistics (ONS) on behalf of the Welsh Government. ONS's highly trained interviewers will collect responses through face-to-face interviews and its researchers will compile the results and pass it to the Welsh Government for analysis.

The 10-yearly census, measures of inflation, the national accounts, and population and migration statistics are some of the ONS’s highest-profile outputs.

How will the information be used?

The information obtained from the study will be delivered to the Welsh Government. Its researchers will analyse the results, which will assist in policy- and decision-making, and in directing resources to where they are needed most.

Do I have to take part?

This study is very important and we need your help to make it a success. No-one has to take part if they do not want to, but for us to paint an accurate picture of society in Wales, it is vital that we interview as many people as possible, from all walks of life, living in all parts of Wales.

Is the study confidential?

Yes. The information you give us will be treated as confidential as directed by the Code of Practice for Statistics. It will be used to produce statistics that will not identify you or anyone in your household. All such statistics produced are subject to the Code and the same standards of protection are applied to your information at all times.

Why have I been selected?

A sample of households is selected at random from the Royal Mail's Postcode Address File. Once selected, a household cannot be replaced by another as this would affect the representativeness of the sample. This means your participation is very important to the success of this study by ensuring all groups in Wales are properly represented.

What is ONS’s responsibility to the public?

You can read about the commitments ONS makes to those taking part in its studies in our ONS Respondent charter for surveys of households and individuals.
