## Interpretation of Incidence Rates Data

### Incidence Rate Report for Louisiana by County

Breast, 2009-2013

All Races (includes Hispanic), Female, All Ages

Sorted by Rate

**Explanation of Column Headers**

**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.

Data for the United States does not include data from Nevada

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 1969-2014 US Population Data File is used for SEER and NPCR incidence rates.

‡ Incidence data come from different sources. Due to different years of data availability, most of the trends are AAPCs based on APCs but some are APCs calculated in SEER*Stat. Please refer to the source for each area for additional information.

* Data has been suppressed to ensure confidentiality and stability of rate estimates. Counts are suppressed if fewer than 16 records were reported in a specific area-sex-race category. If an average count of 3 is shown, the total number of cases for the time period is 16 or more which exceeds suppression threshold (but is rounded to 3).

Interpret Rankings provides insight into interpreting cancer incidence statistics. When the population size for a denominator is small, the rates may be unstable. A rate is unstable when a small change in the numerator (e.g., only one or two additional cases) has a dramatic effect on the calculated rate.
