UK's Office for National Statistics out with an announcement earlier 19 Oct

  • We will move to using the new GDP publishing model in 2018, with the first estimate of monthly GDP (for the reference month of May) being introduced in July 2018 and the first quarterly GDP estimate (for Q2 2018) under the new model being introduced in August 2018.

  • We will develop a package of products to be released as part of the new monthly and quarterly publications under the new model in collaboration with users, with the aim of providing a clear and coherent picture of economic activity

  • We will take a number of steps to ensure that any negative impact on data content in the first estimate of GDP is minimised. For example, we will be reviewing our survey and broader data processing timetables as well as our estimation and forecasting methods

  • We will publish an article in Spring 2018 explaining the changes to the publication model in more detail, the products that we will produce under the new model and a clear schedule of publication dates from the date of implementation.

One for the data geeks. Put the date in your diary.

I love the line in para 2 "...with the aim of providing a clear and coherent picture of economic activity". I'm sure it will be as clear and coherent as mud.
