Beginning this week, the U.S. Census Bureau embarks on a mammoth task: counting the entire population of the United States in a span of about six weeks. In past census years, Minnesotans have responded in greater numbers than residents of other states. But even in Minnesota, communities of color and immigrants were significantly undercounted during the last census. Minnesota Public Radio's Shirley Idelson reports on efforts to *reduce the undercount* this time around.
