Dataset Language
Acorn Wellbeing data supplied under licence from CACI ltd. Acorn is a geodemographic classification that segments the population according to their lifestyle, life stage and affluence.

It can be useful for better understanding our residents, knowing how best to communicate with them and for informing service planning. The acorn wellbeing dataset is a postcode aggregation for every household in Hertfordshire coded by acorn category, and shows the modal (most common) category for each postcode.

The data is strictly for use only by internal employees and any sharing enquiries can be directed to
