| Notes: Created by statecancerprofiles.cancer.gov on 10/04/2023 5:11 am. Trend2 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.Rate Comparison Above when 95% confident the rate is above and Rate Ratio3 > 1.10Similar when unable to conclude above or below with confidence.Below when 95% confident the rate is below and Rate Ratio3 < 0.901 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 Version 4.8.0.0. 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 (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 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, Allamakee County, Appanoose County, Audubon County, Buena Vista County, Butler County, Calhoun County, Cass County, Cherokee County, Chickasaw County, Clarke County, Clayton County, Crawford County, Davis County, Decatur County, Delaware County, Emmet County, Fayette County, Franklin County, Fremont County, Greene County, Grundy County, Guthrie County, Hamilton County, Hancock County, Harrison County, Henry County, Howard County, Humboldt County, Ida County, Iowa County, Jefferson County, Jones County, Keokuk County, Kossuth County, Louisa County, Lucas County, Lyon County, Madison County, Mills County, Mitchell County, Monona County, Monroe County, Montgomery County, O'Brien County, Osceola County, Page County, Palo Alto County, Pocahontas County, Poweshiek County, Ringgold County, Shelby County, Tama County, Taylor County, Union County, Van Buren County, Washington County, Wayne County, Winnebago County, Winneshiek County, Worth County, Wright County Trend for the following could not be reliably determined due to small number of deaths per year: Benton County, Bremer County, Buchanan County, Carroll County, Cedar County, Clay County, Clinton County, Dallas County, Dickinson County, Floyd County, Hardin County, Mahaska County, Marion County, Marshall County, Muscatine County, Sac County, Sioux County, Wapello 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 does not include Puerto Rico. |
