Noncitizens are less likely to participate in a census with citizenship question, study says

According to a new study, adding a citizenship question causes fewer noncitizens to answer all questions fully. This is especially apparent among people from Latin America, according to the study.

Republicans called for this question to be added to the census. Now, many noncitizens, especially those who do not have a Social Security Number are providing incomplete census answers. This potentially causes undercounts, according to the U.S. Census Bureau and the University of Kansas.

The study focused on individual households instead of using census tracts.
