About a third of Latinos in America say they've been personally discriminated against when it comes to applying for jobs, being paid equally or considered for promotions — and when trying to rent a room or apartment or buy a house. Slightly more (37 percent) say they've personally experienced racial or ethnic slurs because of their race or ethnicity.These are some of the key findings NPR is releasing Wednesday from a polldone with the Robert Wood Johnson Foundation and the Harvard T.H. Chan School of Public Health. The survey of 3,453 adults looked at a wide range of issues in many groups and included 803 adults identifying as Latino or Hispanic. The poll also surveyed African-Americans, white Americans, Native Americans, Asian-Americans and LGBTQ adults. We are releasing data by each of these groups on a weekly basis.Overall, Latinos reported substantial and significant discrimination in their day-to-day lives. In addition to those who said they'd been slurred, 33 percent say they've experienced offensive comments or negative assumptions about their race or ethnicity at some point in the past. Nonimmigrant Latinos and Latinos with a college degree are both more likely to report various forms of one-to-one personal discrimination.When we drilled down into the data, we found that the experience for immigrants and nonimmigrants varied significantly in employment as well, with immigrant Latinos experiencing discrimination on the basis of race and ethnicity more than twice as often as nonimmigrant Latinos. There were also divides based on what kind of neighborhood people live in.The survey was a large, nationally representative sample, conducted from Jan. 26 to Apr. 9. The findings on Latino Americans have a margin of error of plus or minus 4.5 percentage points at the 95 percent confidence level. The poll is part of a larger NPR project, "You, Me and Them: Experiencing Discrimination in America."Our poll has its roots in research showing disparities in the health and life expectancies of minorities in America. There is a growing body of research showing that day-to-day exposure to discrimination increases the risk of various diseases, raises the rate of premature birth and may decrease overall life expectancy.Dr. David Williams, a Harvard professor, put it this way in a recent interview with NPR's Michel Martin:
