Five Year Liver Cancer Incidence Data
Five Year measures can be used to identify trends and patterns of cancer incidence over time and in different geographic areas. Five year aggregate measures are available at the state and county level. Five year aggregate data is used to reduce the presence of due to small numbers; allowing display of data, and stabilization of rates to better evaluate trends. Even with this aggregation some values still need to be suppressed.
- The Average Annual Count is the average number of newly diagnosed malignant cancers per year in the five year period.
- The Crude Rate (Per 100K) is the rate of newly diagnosed malignant cancers per 100,000 Population during the five year period.
- The Age Adjusted Rate (Per 100K) is the age adjusted rate of newly diagnosed malignant cancers per 100,000 Population during the five year period. Age adjustment to the 2000 Standard US Census is done to allow direct comparison of rates in counties and state with different population age distributions.
As part of the February 2023 update the Cancer Data source was updated to come directly from the State Health Registry of Iowa, Iowa Cancer Registry. The new data source allows data to be published with a shorter delay from the prior National SEER Data source. Due to this change the measures published for 2000-2016 may be slightly different than previously available.
