Sorted by trend

Explanation of Column Headers

State/County - The site and sex combination for this comparison.

Priority Index ¹ - The priority index is based upon the direction of the trend and the rate comparison. An index of 1 is the highest priority - that trend is rising and the rate is already higher. An index of 9 is the lowest priority - the trend is falling and the rate is already lower.

Recent Trends - This is an interpretation of the AAPC:

Rising when 95% confidence interval of average annual percent change is above 0.
Stable when 95% confidence interval of average annual percent change includes 0.
Falling when 95% confidence interval of average annual percent change is below 0.

AAPC (95% Confidence Interval) - The Average Annual Percent Change is the change in rate over time. These AAPCs are based upon APCs that were calculated by Joinpoint Regression Program

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.

when 95% confidence interval of average annual percent change is below 0.
Rate Comparison
Above

when 95% confident the rate is above and Rate Ratio³ > 1.10
Similar

when unable to conclude above or below with confidence.
Below

when 95% confident the rate is below and Rate Ratio³ < 0.90

* Data has been suppressed to ensure confidentiality and stability of rate and trend estimates.
** Data are too sparse to provide stable estimates of annual rates needed to calculate trend.
¹ Priority indices were created by ordering from rates that are rising and above the comparison rate to rates that are falling and below the comparison rate.
² Recent trend in death rates is usually an Average Annual Percent Change (AAPC) based on the APCs calculated by Joinpoint. Due to data availability issues, the time period and/or calculation method used in the calculation of the trends may differ for selected geographic areas.
³ Rate ratio is the county rate divided by the US rate. Previous versions of this table used one-year rates for states and five-year rates for counties. As of June 2018, only five-year rates are used.
Source: Death data provided by the National Vital Statistics System public use data file. Death rates calculated by the National Cancer Institute using SEER*Stat. Death rates are age-adjusted to the 2000 US standard population (20 age groups: <1, 1-4, 5-9, ... , 80-84, 85-89, 90+). The Healthy People 2030 goals are based on rates adjusted using different methods but the differences should be minimal. Population counts for denominators are based on Census populations as modified by NCI. The US Population Data File is used with mortality data.
Note: 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. Suppression is used to avoid misinterpretation when rates are unstable.

State Cancer Registries may provide more current or more local data. Data presented on the State Cancer Profiles Web Site may differ from statistics reported by the State Cancer Registries (for more information).

Data for the following has been suppressed to ensure confidentiality and stability of rate and trend estimates:
Buffalo County, Campbell County, Corson County, Deuel County, Douglas County, Haakon County, Hanson County, Harding County, Hyde County, Jackson County, Jones County, Mellette County, Miner County, Sanborn County, Stanley County, Sully County, Ziebach County

Trend for the following could not be reliably determined due to small number of deaths per year:
Bennett County, Brule County, Jerauld County, Lyman County, McPherson County, Oglala Lakota County, Potter County, Todd County

Interpret Rankings provides insight into interpreting cancer 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.

Data for United States do not include Puerto Rico.
