Figure 2.

Age-adjusted incidence rate ratios for breast, prostate, and lung cancer by sex, race, and ethnicity in California (2015-2019). The figure is plotted on log scale; however, axis labels for incidence rate ratios are not on log scale for interpretability. Some confidence intervals extend beyond the plot limit. Rurality was defined as the proportion of residents in rural areas within zones and for the analysis was categorized into 7 levels: 0% (not rural), >0% to <10%, 10% to <20%, 20% to <30%, 30% to <40%, 40% to <50%, and 50+% (12). We used census tract–level data on rurality, which the US Census defines based on percent of residents who reside in blocks that are designated as rural. Zone-level rurality was calculated using population-weighted census tract–level data on rurality from Census 2010. AAPI = Asian American/Pacific Islander.
