Per 1,000,000; IRs are standardized by age category and year with the exception of the IRs for each age category of diagnosis which are standardized by year only.
Information on race/ethnicity is missing for 3.3% (n=21) and 4.4% (n=55) melanoma cases in Texas and SEER 13, respectively.
Includes non-Hispanic non-Whites.
Four-year increments, except for 2011-2013 which is a three-year increment.
Low area-level poverty category includes those living in a county with ≤15% of households below the poverty level; High area-level poverty category includes those living in a county with >15% of households below the poverty level.
