Next we use population data with the counts to calculate crude rates for each of the 19 and 20 age groups. The populations must be for the same geographic area, sex, race, and years (the sum of the black female populations for 2018-2022 in the SEER 21 registries).
In this step, we are calculating the crude, age-specific rates. A crude incidence rate is the number of new cancers of a specific cancer site or type occurring in a specified population during a year, usually expressed as the number of cancers per 100,000 population at risk. It is calculated using the following formula:
Age | Count | Population | Crude Rate |
---|---|---|---|
00 years | 0 | 600,100.000 | 0.000 |
01-04 years | 0 | 2,448,220.000 | 0.000 |
