Due to education being funded primarily through local and state revenue, the quality of education varies greatly depending on the geographical location of the school. In some areas, education is primarily funded through revenue from property taxes; therefore, there is a direct correlation in some areas between the price of homes and the amount of money allocated to educating the area's youth. A 2010 US Census showed that 27.4% of all African-Americans lived under the poverty line, the highest percentage of any other ethnic group in the United States. Therefore, in predominantly African-American areas, otherwise known as 'ghettos', the amount of money available for education is extremely low. This is referred to as "funding segregation". This questionable system of educational funding can be seen as one of the primary reasons contemporary racial segregation continues to prosper. Predominantly Caucasian areas with more money funneled into primary and secondary educational institutions, allow their students the resources to succeed academically and obtain post-secondary degrees. This practice continues to ethnically, socially and economically divide America.
