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

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 Average Annual Percent Change (AAPC) based on the APCs calculated by Joinpoint Regression Program. Due to data availability issues, the time period used in the calculation of the joinpoint regression model may differ for selected counties.
3 Rate ratio is the county rate divided by the US rate.

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 (19 age groups: <1, 1–4, 5–9, … , 80–84, 85+). The Healthy People 2020 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 1969-2011 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:
Adair County, Adams County, Audubon County, Chickasaw County, Clarke County, Davis County, Decatur County, Franklin County, Fremont County, Guthrie County, Hancock County, Howard County, Humboldt County, Ida County, Jefferson County, Keokuk County, Louisa County, Lyon County, Mills County, Monroe County, Montgomery County, Osceola County, Palo Alto County, Pocahontas County, Ringgold County, Taylor County, Van Buren County, Wayne County, Winnebago County, Worth County

Trend for the following could not be reliably determined due to small number of deaths per year:
Allamakee County, Grundy County, Hamilton County, Iowa County, Lucas County, Mitchell County, Monona County, Winneshiek County, Wright County
