These models have been developed from commissioning titles' research and appropriate demographic factors and are regularly updated to ensure that they continue to reflect current research findings. The amount of readership research being undertaken by regional and local newspapers is on the increase, whereas the proportion of titles with RPC figures based on actual research was barely a third just five years ago. Today the figure is about half of all titles.
JICREG uses the JICPOPS annually updated population and household total and postcode sector lists.
JICREG data are complex, with hundreds of separate fields on over 1,000 titles. The Newspaper Society database provides the source of basic newspaper information used by JICREG and a sophisticated electronic questionnaire system has been developed for checking data that publishers supply for inclusion.
JICREG data are released quarterly and the release dates for 2009 are planned for 19 January, 20 April, 13 July and 26 October, to incorporate new circulation and research data.
