Abstract
Background: The United States Centers for Disease Prevention and Control (CDC) National Program of Cancer Registries (NPCR) works to disseminate cancer surveillance data to multiple audiences in accessible, discoverable, and usable formats. To this end, CDC released the official federal cancer statistics, U.S. Cancer Statistics (USCS), in a data visualization tool available at www.cdc.gov/cancer/dataviz . We made further enhancements to the online tool since its initial release in 2017. Aim: We describe the process and enhancements made to the USCS data visualization tool's content, graphical displays, and sharing capabilities. Methods: CDC partnered with Agency for Toxic Substances and Disease Registry's Geospatial Research, Analysis, and Services Program to further work initiated by a group of cancer registrars, program planners, epidemiologists, computer programmers, and communication specialists to improve the visual presentation of USCS cancer incidence and mortality data. We conducted usability testing and implemented changes to the Web site's layout and added content, including county-level data, survival data, and prevalence estimates. Results: New features include county statistics, survival, prevalence, Puerto Rico data, and tobacco-, alcohol-, and obesity-related cancers data displays. The tool was also enhanced to better display on mobile devices. Data displays on national and state incidence, mortality and trends are available as maps and bar charts with interpretive text when users scroll over each graphic. Users can customize displays of overall and cancer-specific statistics, download data tables, and share each page via social media. Conclusion: Surveillance data are fundamental to measure progress and target action. CDC's interactive USCS data visualization tool is designed to make cancer data more accessible and usable to multiple users, including the general public, media, policy makers and planners. We will continue to improve the tool's accessibility and usefulness to facilitate the interpretation and sharing of cancer data.
