Types of official statistics

What is an official statistic?

An official statistic is:

  •  produced by an organisation named by the Statistics and Registration Service Act 2007 and described by that organisation as an official statistic or part of a set of official statistics.
  • any set of statistics produced by an organisation named under secondary legislation and described by that organisation as an official statistic or part of a set of official statistics.

This broad definition of official statistics means that the scope of official statistics can be adapted over time to suit changing circumstances.
