In the United States, despite the efforts of equality proponents, income inequality persists among races and ethnicities. Asian Americans have the highest median income, followed by White Americans, Hispanic Americans, African Americans, and Native Americans. A variety of explanations for these differences have been proposed—such as differing access to education, two parent home family structure (70% of African American children are born to parents who are not legally married), high school dropout rates and experience of discrimination and deep-seated and systemic anti-Black racism—and the topic is highly controversial. When the Civil Rights Act of 1964 was passed, it became illegal for employers to discriminate based on race; however, income disparities have not flattened out. After the passage of the act, the wage gap for minority groups narrowed, both in absolute difference with white wages and as a percentage of white wages, until the mid-1970s; at this time, progress for many racial minorities slowed, stopped, or reversed. As of 2009, the median weekly wage for African American and Hispanic workers was about 65 percent and 61 percent that of white workers, respectively. Asian workers' median wage was about 110 percent that of white workers. Overall, minority women's wages in comparison to those of white women are better than minority men's wages when compared to those of white men. Wages from the labor market are the primary source of income for most families in America, and income is a socio-demographic status indicator that is important in understanding the building of wealth. History of the racial wage gap The documented history of the racial wage gap in the United States goes back before the Civil Rights Act, where many modern causes of racial wage inequity, such as educational disparities and discrimination, stem from were even more prevalent. Public state records from the 1930s indicate white owned schools in the south spent approximately $61 per student, or $1,074.14 in 2018 dollars when adjusted for inflation, compared to just $9 per student, or $158.48 in 2018 dollars. Simultaneously, the same schools saw a discrepancy in school time, with white schools in sessions for 156 days on average, compared to 123 days on average for black schools. While statistical measures of wage discrepancy between black individuals and their white counterparts exist, wage inequity is still poorly understood due to a lack of literature with solid empirical data to link data with an accurate model of wage
