Historical Trends Graph

Purpose:

Use this graph to explore the relationship over time of levels and trends in cancer rates for geographic areas and for demographic subgroups. Potential health disparities can be explored to identify opportunities or to evaluate the success of prior interventions.

While useful for planning and evaluating cancer control, these trends represent an ecological analysis. An cancer epidemiologist knowledgeable about the area and its demographics and health resource utilization should assist in interpreting unexpected trends.

Cancer statistics require careful interpretation. See the information page about interpret rankings for insight into interpreting cancer statistics particularly if you are a new user of cancer statistics.

The Quick Reference Guide provides an introduction to the interactive features of this graph.
