Ministry of Health Annual and Regional Data Explorer

The New Zealand Health Survey is a survey conducted by the Ministry of Health to provide information about the health and wellbeing of New Zealanders. It became a continuous survey in 2011 and every year around 14,000 New Zealand households take part in the survey.

We worked with the Ministry of Health to improve the communication of the most up-to-date results via web-based, interactive data visualisations. As part of the project we carried out the user experience design as well the development of two web applications. The Annual Data Explorer enables users to explore health topics and indicators and provides a national view on the data. With the Regional Data Explorer users can drill into and compare data for selected regions, i.e. on District Health Board, Public Health Unit and Regional Council level.

Data visualisation outputs supported are interactive time series, subgroup comparisons (e.g. ethnicity, age groups, neighbourhood derivation), rate ratios and maps for regional comparisons. Outputs are also available for download in various formats. As part of the project additionally the data processing and updating process was streamlined.
