Rate Comparison

* Data has been suppressed to ensure confidentiality and stability of rate and trendestimates.^{2}**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 Ratio^{3}> 1.10**Similar**when unable to conclude above or below with confidence.**Below**when 95% confident the rate is below and Rate Ratio^{3}< 0.90** 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 Average Annual Percent Change (AAPC) based on the APCs calculated by Joinpoint Regression Program (Version 4.3.0.0). 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 1969-2013 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.
