People classified as 'blancos' (whites) were the insulares or "Filipinos" (a person born in the Philippines of pure Spanish descent), peninsulares (a person born in Spain of pure Spanish descent), Español mestizos (a person born in the Philippines of mixed Austronesian and Spanish ancestry), and tornatrás (a person born in the Philippines of mixed Austronesian, Chinese and Spanish ancestry). Manila was racially segregated, with blancos living in the walled city of Intramuros, un-Christianized sangleys in Parían, Christianized sangleys and mestizos de sangley in Binondo, and the rest of the 7,000 islands for the indios, with the exception of Cebu and several other Spanish posts. Only mestizos de sangley were allowed to enter Intramuros to work for whites (including mestizos de español) as servants and various occupations needed for the colony.
