The United States Census Bureau has released the initial data from the 2010 Census.
Michigan is the only state that lost population (we lost 54,804). You can find an interactive map at the link below to investigate the early data for your state. Michigan will of course lose some representation in the U.S. Congress, along with Illinois, Iowa, Louisiana, Massachusetts, Missouri, New Jersey, New York, Ohio and Pennsylvania.
I’ll post more in the coming days as more data is released from the U.S. Census Bureau.
