Notes: Age-specific Rate is per 100,000 population in a specific age group.  Adding and subtracting the number shown after the ± symbol from the rate creates a confidence interval indicating that the true rate lies between the lower and upper bounds of this interval with 95% statistical confidence.

Average Number
is the number of new invasive cancer cases diagnosed in the period, divided by the number of years in the period.

Case
: A case is defined as a person with any newly diagnosed cancer with a behavior code of 3 (malignant primary site). Both in-situ and invasive urinary bladder cancer cases are included, in order to be consistent with national tabulations from the National Cancer Institute.
