Confidence Intervals for Ranks (CI*Rank)

The Confidence Intervals for Ranks (CI*Rank) website presents confidence intervals for ranks of age-adjusted US cancer incidence and mortality rates by geographic region. Confidence intervals for ranks of age-adjusted US mortality rates for other causes of death are also provided.

Ranking health indices is useful for seeing where a geographic area stands in comparison to other areas. However, ranks are inherently random and are dependent on the variability of rates. Providing ranks and their level of uncertainty (i.e., the confidence intervals) together demonstrates not only the variability of that area's rate but also the variability of closely ranked areas' rates.

The following data sources are available in CI*Rank:

  • US Mortality Data
    From the National Center for Health Statistics (NCHS). Age adjusted rates obtained from SEER*Stat.
  • US Cancer Incidence
    From the North American Association of Central Cancer Registries (NAACCR) CiNA Analytic file.
