Yes. The Census counts both citizens and non-citizens, including undocumented immigrants. Historically, undocumented immigrants have been undercounted. Difficulties with the English language affect the ability of many individuals to understand and answer the Census. Although the controversial citizenship question will no longer be printed on the Census, many non-citizens may still be suspicious of government agencies and fear that responding to the questions in the Census may result in their deportation or incarceration by immigration and law enforcement officials. While federal law prohibits personal information from being shared, even with another government agency, many are understandably still worried.
