Woodrow, Karen A. 1990. “Using Census and Survey Data to Measure Undocumented Immigration and Emigration From the United States,” Presented at the Work Session on Migration Statistics, held in Geneva, Switzerland, April 9-11, 1990, and sponsored by the United Nations Statistical Commission and Economic Commission for Europe, Conference of European Statisticians. Abstract.


This paper describes Census Bureau research to measure undocumented immigration and emigration, a task that is complicated by the nature of both phenomena and the paucity of relevant data. Measuring the immigrant population is a prerequisite for measuring undocumented immigration. Measuring emigration is a correlate of measuring undocumented immigration. The Census Bureau has endeavored to estimate these unknown stocks and to measure these unknown flows with data collection and analytic research.
