The Process

Results publication

The Quarterly Summary (or Press Release)

The Quarterly Summary is the document released in the public domain by RAJAR every quarter. Normally published about 5 weeks after the end of each fieldwork period, the Quarterly Summary gives the latest 'top-line' results for both BBC and Commercial Radio stations. Currently, publication takes place on a Thursday, with use of the data embargoed until 7.00am on that day.

For each station, the Quarterly Summary gives the following variables:

  • reporting requirement (Q, H or Y)
  • total adult population of the station's TSA in 000s
  • weekly reach in 000s and % of TSA
  • total hours spent listening to the station
  • average hours per head and per listener
  • market share in TSA

All results are given on an average week and for Adult 15+, unless otherwise specified.

A listener is defined as a person who tuned in for at least 5 minutes during the diary week.

Topline results are made available to the public free of charge. Any more detailed information (see Aggregated Data and Respondent Level Data) is only available to RAJAR subscribers.

Aggregated Data

Aggregated data are tables published in a pre-set format, i.e. with pre-determined age brackets, timebands, etc. For more flexibility of analysis, please see next section entitled Respondent Level Data.

'Standard Results' (also known as 'Volume tables') for Commercial Stations

'Standard Results' (or Volumes tables) are provided to each participating Commercial Radio station or group for their own services. These results are made available electronically to stations at 1.30pm on the data release day - i.e. the Wednesday. This data is embargoed until 7.00am on the Thursday morning 'Press Release' day.

The 'Summary of Results' includes data for all participating commercial services as well as BBC Network services.

Respondent Level Data

Respondent Level Data is the full database of results collected by RAJAR and published each quarter. Using this database with a data analysis software allows the subscriber to determine the specifications of the analysis to be run and gives access to results not covered by the Aggregate Data. It also allows the user to plan an advertising campaign based on the reach and frequency model.

Data analysis software developers that allow the loading of RAJAR data are commonly referred to as the RAJAR Bureaux.
