For single data years: Death rates are calculated based on the resident population of the United States for the data year involved. For census years (e.g. 2010), population counts enumerated as of April 1 are used. For all other years, population's estimates as of July 1 are used. Postcensal population estimates are used in rate calculations for years after a census year and match the data year vintage (e.g. July 1, 2011 resident population estimates from Vintage 2011 are used as the denominator for 2011 rates). Intercensal population estimates are used in rate calculations for the years between censuses (e.g. 1991-1999, 2001-2009). Race-specific population estimates for 1991 and later use bridged-race categories.
For multiple data years: Death rates are calculated based on the sum of the resident populations for each of the data years involved (e.g. the denominator of a rate for 2011-2013 combined is the sum of the population estimates for 2011, 2012, and 2013). For census years (e.g. 2010), population counts enumerated as of April 1 are used. For all other years, population's estimates as of July 1 are used. Postcensal population estimates are used in rate calculations for years after a census year and match the data year vintage (e.g. July 1, 2011 resident population estimates from Vintage 2011 are used as the denominator for 2011 rates). Intercensal population estimates are used in rate calculations for the years between censuses (e.g. 1991-1999, 2001-2009). Race-specific population estimates for 1991 and later use bridged-race categories.

Age-adjustment Definition
This information is relevant only for tables containing age-adjusted cancer rates. An age-adjusted rate is a weighted average of the age-specific (crude) rates, where the weights are the proportions of persons in the corresponding age groups of a standard population. The potential confounding effect of age is reduced when comparing age-adjusted rates computed using the same standard population. Several sets of standard population data are included in SEER*Stat. These include the 2000 US standard population as well as standard millions for the US population (1940, 1950, 1960, 1970, 1980, 1990, and 2000), the 1991 Canadian population, the European population, and the world population (see 2000 US Standard Population vs. Standard Million for more discussion). Detailed explanation can be found on the National Cancer Institute (NCI) website.
Important Note
This note refers to tables which contain data for cancer death counts and rates by age and race. Some variables in these tables contain data about cancer incidence only for a small number of counties. This is mainly the case for some age groups (for example Population Under 18 Years) and the reason for this is the fact that cancer rates are generally low for this age group. In the other case, some races and ethnic groups which are not widely distributed across the United States or their population is relatively small (for example American Indian or Alaska Native) have small cancer death counts and cancer rate estimates based on fewer than 20 deaths are considered unreliable and are not displayed. This is a general not to underline why some reports and maps are sparse.

Deaths due to the malignant cancers of breast (categorized as ICD-10 code C50, International Classification of Diseases 10th Revision) calculated as the rate per 100,000 population. Estimates based on fewer than 20 deaths are considered unreliable and are not displayed. Please check Data Description for more information.
