Religious affiliation among Latinos varies by immigrant generation. Among foreign-born Latinos, nearly seven-in-ten (69%) identify as Catholic. However, the share who identify as Catholic falls to 59% among the second generation, and 40% among the third generation. By contrast, the share of Latinos who identify as Protestant rises through the generations. Some 16% of immigrant Latinos say they are Protestant. Among the third generation, the share is 30%. Foreign-born and native-born Latinos are about as likely to say they are evangelical Protestants—13% and 14%, respectively.
The survey’s margin of error is the largest 95% confidence interval for any estimated proportion based on the total sample – the one around 50%. For example, the margin of error for the entire sample is ± percentage points. This means that in 95 out of every 100 samples drawn using the same methodology, estimated proportions based on the entire sample will be no more than percentage points away from their true values in the population. Sampling errors and statistical tests of significance used in this report take into account the effect of weighting. In addition to sampling error, one should bear in mind that question wording and practical difficulties in conducting surveys can introduce error or bias into the findings of opinion polls.
