Potential policy impact
WHS makes a vital contribution to informing and monitoring
public health strategy in Wales. It provides estimates of health
status, determinants and service use at national and local level
(health board and unitary authority) and for key subgroups.
WHS also contributes to setting and monitoring targets and indicators, and development of joint local health, social care and wellbeing strategies.
WHS collects data from approximately 15,000 adults and 3,000
children annually in 10,000 households in Wales. It uses a short
paper-based household questionnaire, and individual self-completion
In 2007 data collection for children aged 0-15 was extended with the introduction of longer age-specific questionnaires, and for children aged 2-15 height and weight measurements.
In 2013 the WHS no longer measures the height and weight of children aged 2-15.
