The 2010 census map verifies what most people already suspected. Do you have data that contradicts their findings?
Thank you. It is not due to conflict I asked you. Before I accept data, I must know its source, who collected it and when, and for what purpose, and I must have access to the raw data itself. By answering my question, you have satisfied this. I have a higher standard for accepting data than most people, you see. Without this information I asked of you, and which you so politely answered, I simply consider the data random numbers of type randU (made up in someone's head) until I know that information.
This data is a graphical representation of those checking the African-American checkbox on their 2000 Census forms. The data was collected in 2000 and collated into this form by the University of Michigan using software they wrote. The purpose of collecting the data was to satisfy federal law. The purpose in collecting this part of the data is politically motivated to satisfy 'fair practices' policies. Nothing about actual skin color or heritage forces a choice on the form. There being no pure race anywhere on Earth, it is hard to consider anyone 'black', 'white', 'red', or 'yellow'. People of African heritage are often considered to be 'black', particularly if they come from central Africa. The term 'nigger' is a corruption of the nation of Nigeria, used in a denigrating manner. The term 'negro' stems from Spanish and Latin, meaning 'dark'. Depending on where you are, it may be used as an insult, or simply used to describe people of such heritage, similar to the way we use 'black' (and the way most people used 'negro' in the past).
That said, there are those brought into the U.S. over time as slaves, originally captured in Africa, and their descendants are still here (though fortunately now freed). Starting from owning nothing, their opportunities over the years have of course been limited. It was not until the 60's they had anything resembling equal rights at all, despite the 13th and 14th amendments. This includes obtaining education. It has been a difficult history for them, especially since Democrats are still racist, and are still trying to 'put them in their place'. The plantations of the past are not gone. They just moved into the cities. The whole attitude of keeping these people 'in their place' is just sick.
The only reason Obama became President is because he is one of the owners of that new 'plantation', so to speak. He enslaved his own, just as free black men enslaved their own in the South.
The States themselves have no color. The 2020 Census may be rather enlightening of the changes that occurred in the last decade, once collected and collated.
