Comparison of 2007–2011 cancer mortality rates for three mutually-exclusive groups of U.S. counties: (1) not experiencing current poverty, (2) experiencing current but not persistent poverty, and (3) experiencing current and persistent poverty.

Note. Cancer mortality rates are expressed as deaths per 100,000 people per year, except breast and cervical cancers (deaths per 100,000 females per year) and prostate cancer (deaths per 100,000 males per year). Two-sample t-tests were used to estimate unadjusted differences in cancer mortality rates for (2) counties experiencing current but not persistent poverty (reference category) versus (3) counties experiencing current and persistent poverty, and multivariable linear regressions were used to estimate adjusted differences in cancer mortality rates. Adjusted models controlled for county-level metropolitan status; Census region; percent of residents that are female, Non-Hispanic black, Hispanic, with a bachelor’s degree or higher, and unemployed; and median household income. Ref=reference; SE=standard error; diff=difference; est.=parameter estimate.
