Abstract Survival differences between socioeconomic groups in colorectal cancer have been studied for patients diagnosed in the 90s and 00s, but research on recent patients using individual measures of socioeconomic position is limited. CRCBaSe, a database of linked national registry data, was used to analyse stage I–III colorectal cancer patients diagnosed in Sweden between 2008 and 2021. The exposures of interest were income and education.
