This coverage report presents the findings of an Alternative Enumeration (AE) conducted in Woodburn, Oregon, for the U.S. Census Bureau. Five hypotheses of the causes of undercount were suggested by Brownrigg and Martin (1989) and served as the basis of this research. It was predicted that Hispanics in Woodburn would conceal their living arrangements in order to protect their over-occupancy of limited housing. It was also suggested that language barrier would cause undercount among this population.
