Acorn/UPRN Data

About the dataset

Acorn is a classification that segments the UK population. By analysing demographic data, social factors, population and behaviour, it provides information and an understanding of different types of patients and household dynamics. 

The data is aggregated and is aimed to assist in identifying vulnerable patients who require further living assistance thus reducing discharge delays/inappropriate length of in-patient stays.
