Interpretation of Incidence Rates Data
Incidence Rate Report for Massachusetts by County
All Cancer Sites (All Stages^), 2017-2021
All Races (includes Hispanic), Both Sexes, Ages <50
Sorted by Name
Explanation of Column HeadersObjective - The objective of *** is from the Healthy People 2020 project done by the Centers for Disease Control and Prevention.
Incidence Rate (95% Confidence Interval) - The incidence rate is based upon 100,000 people and is an annual rate (or average annual rate) based on the time period indicated. Rates are age-adjusted by 5-year age groups to the 2000 U.S. standard million population.Recent Trends - This is an interpretation of the AAPC/APC:
- Rising when 95% confidence interval of AAPC/APC is above 0.
- Stable when 95% confidence interval of AAPC/APC includes 0.
- Falling when 95% confidence interval of AAPC/APC is below 0.
AAPC/APC (95% Confidence Interval) - the change in rate over time
- Average Annual Percent Change - AAPCs are based upon APCs that were calculated by Joinpoint Regression Program
- Annual Percent Change - APCs calculated in SEER*Stat.
Other Notes
- Larger confidence intervals indicate less stability of the data. This is often due to low counts that are not quite low enough to be suppressed.
- Data is currently being suppressed if there are fewer than 16 counts for the time period.

State Cancer Registries may provide more current or more local data.
† Incidence rates (cases per 100,000 population per year) are age-adjusted to the 2000 US standard population (19 age groups: <1, 1-4, 5-9, ... , 80-84, 85+). Rates are for invasive cancer only (except for bladder cancer which is invasive and in situ) or unless otherwise specified. Rates calculated using SEER*Stat. Population counts for denominators are based on Census populations as modified by NCI. The US Population Data File is used for SEER and NPCR incidence rates.
Rates and trends are computed using different standards for malignancy. For more information see malignant.html.
^ All Stages refers to any stage in the Surveillance, Epidemiology, and End Results (SEER) Summary/Historic Combined Summary Stage (2004+).
⋔ Results presented with the CI*Rank statistics help show the usefulness of ranks. For example, ranks for relatively rare diseases or less populated areas may be essentially meaningless because of their large variability, but ranks for more common diseases in densely populated regions can be very useful. More information about methodology can be found on the CI*Rank website.
