According to the results of recent CARA Catholic Polls (CCP), generational changes are underway that are transforming the demography of the U.S. Catholic population. Through a combination of immigration and different fertility rates among sub-groups of the population, racial and ethnic identities of the Catholic population now vary significantly by generation.
As the figure below shows, differences between these groups are not limited to age. Estimates based on the aggregated results of multiple recent CCPs indicate that three in four of the oldest generation of Catholics self-identifies their race and ethnicity as non-Hispanic White. By comparison, just fewer than four in ten of the youngest generation of adult Catholics identifies as such.
