SCHS: Cancer Incidence Data Visualization Tools
Technical Notes
Numbers are subject to change as files are updated.
Cases may not sum to totals due to unknown or other values.
Cancers of the urinary bladder and female breast include in situ cases.
Cell sizes with fewer than five cases of cancer incidence are suppressed for confidentiality.
Cancer incidence rates for cell sizes with fewer than 16 cases of cancer are suppressed as they are not stable.
Cancer rates are per 100,000 population and age-adjusted to the 2000 U.S. Standard Population.
Rates are calculated using vintage 2019 non-bridged population estimates for 2017-2019 (based on the 2010 Census), and vintage 2022 non-bridged population estimates for 2020-2021 (based on the 2020 Census).
Race & Ethnicity and County cancer statistics are five year aggregates ending in the selected year. For example, 2021 rates are based on aggregate data from 2017 to 2021.
Hispanic ethnicity is independent of race. Hispanic ethnicity is determined by self-report and the National Hispanic Identification Algorithm.
Cancer incidence for American Indians is assumed to be underestimated. Yankaskas BC, Knight K, Fleg A, Rao, C. Misclassification of American Indian Race in State Cancer Data among Non-federally Recognized Indians in North Carolina. Journal of Registry Management. 2009;36(1):7-11.
Incidence rates for 2022 are preliminary.
