The 1964 Civil Rights Act entitles all persons to equal access to restaurants, bars, theatres, hotels, gasoline stations, and similar establishments serving the general public. It also bars discrimination on the basis of race, color, religion, sex, or national origin in the hiring, promotion, and wages of employees of medium-size and large firms. However, this legislation did not immediately result in equality of opportunity of hiring practices. The Act did not require employers to prove that their employment practices were not discriminatory, and many continued to give preferential treatment to white males. The concentration of the Civil Rights Act of 1968 was equality in housing. To prevent discrimination in housing, this act prevented building owners from refusing to sell or rent housing because of a person's race, religion, ethnicity, or sex. An exception is allowed for owners of small multifamily dwellings who reside on the premises.
