Note: The observed changes in Hispanic origin and race counts between Census 2000 and the 2010 Census could be attributed to a number of factors.  Demographic change since 2000, which includes births and deaths in a geographic area and migration in and out of a geographic area, will have an impact on the resulting 2010 Census counts.  Additionally, some changes in the Hispanic origin and race questions' wording and format since Census 2000 could have influenced reporting patterns in the 2010 Census.  Also, in Census 2000 an error in data processing resulted in an overstatement of the Two or More Races population by about 1 million people (about 15 percent) nationally, which almost entirely affected race combinations involving Some Other Race.  Therefore, data users should assess observed changes in the Two or More Races population between Census 2000 and the 2010 Census with caution.
