The review of consultation responses is ongoing and further input from respondents may be sought in the New Year in order to further refine any changes to the current methodology

What is this consultation?

This consultation invites responses on proposed changes to the method of disclosure control applied to aggregated HES outputs.

Why are we having this consultation?

The current disclosure control methodology has been reviewed in order to improve consistency and ease of application, and to reduce risk of identification.

Summary of consultation

The proposal still requires small numbers to be suppressed at certain levels of aggregation (usually small geographical areas). However the way these are currently protected within official statistical outputs is by manual application of secondary suppression. The proposal instead uses rounding of aggregate data as the method of protecting the primary small number suppression.

How to respond

This consultation will run for six weeks from 25 August 2015 until 5 October 2015. We welcome the views of all users of HES data.
