Number of years spent in the U.S.


[ PRELIMINARY VARIABLE: Variable description may change once we confirm the universe and assess the comparability of this variable over time. ]

For individuals born outside the 50 United States and the District of Columbia, YRSINUS indicates how long such persons had been in the United States. In most cases, this information was collected via the question, "In what year did you come to the United States to stay?" If the response to this question was "refused" or "don't know," the interviewer tried to collect the information via an alternatively phrased question: "About how long have you been in the United States?"

The data included in the public use files for YRSINUS are recodes of the responses to these questions, with each answer in the form of a calendar year converted to a number of years present. The calendar year format of the initial question would have increased the precision of responses by discouraging rounding; the recoded format (number of years present) is easier for researchers to analyze.
