COVID-19 cases by notification date and age range. Data is available from 29th of June 2021.

The data is for confirmed COVID-19 cases only based on location of usual residence, not necessarily where the virus was contracted.

The underlying dataset was assessed to measure the risk of identifying an individual and the level of sensitivity of the information gained if it was known that an individual was in the dataset. Age ranges have been combined to minimise these risks.
