+The datasets were collected and published to present the educational level of NC population in different areas. The educational attainment for the black population data can raise concern for the educational equity issue in North Carolina. The combined dataset aims to offer a holistic perspective on educational levels and equity, with a specific focus on the educational attainment of the Black population aged 25 and over.
