Protocol - Birthplace
The respondent completes the self-administered questionnaire by indicating his or her place of birth. If he or she was born in the United States, an additional question captures the state, if known. If he or she was not born in the United States, another open-ended question asks for this location.
The following question has been revised from the original. Where were you born?
[ ] In the United States - Print name of state
[ ] Outside the United States - Print U.S. Territory (e.g., Puerto Rico, U.S. Virgin Islands, Guam) or name of foreign country, etc.
Personnel and Training Required
This question may be self-administered (as in the source protocol) or administered by an interviewer with a paper-and-pencil or computer-assisted interview. The interviewer must be trained to conduct personal interviews with individuals from the general population. The interviewer must be trained and found to be competent (i.e., tested by an expert) at the completion of personal interviews.* The interviewer should be trained to prompt respondents further if a "don’t know" response is provided.
* There are multiple modes to administer this question (e.g., paper-and-pencil and computer-assisted interviews).
Either a paper-and-pencil or computer-assisted instrument may be used. If a computer-assisted instrument is used, computer software may be necessary to develop the instrument. The interviewer will require a laptop computer or handheld computer to administer a computer-assisted questionnaire.

Question asking the respondent in what country he or she was born.
Birthplace is requested to determine if the individual was born in the United States, in a U.S. Territory, or in a foreign country. Large national surveys like the U.S. Census and American Community Survey (ACS) use birthplace data to quantify immigration.
