The map shows how incidence rates for each local authority compare with the England average, and how they have changed over time. These incidence rates are expressed per 100,000 population and are standardised to the European Standardised Population. This is a hypothetical population that assumes that the age structure is the same in both sexes, therefore allowing comparisons to be made between males and females, years, and geographical areas.
The map is released to coincide with the publication of Cancer Registration Statistics, England, 2011. This statistical bulletin examines the most common cancers in 2011, cancer incidence by sex and age group, and cancer incidence by region.
