Zambales is basically an agriculture province.  Major industries here include farming, fishing and mining.  The inhabitants are composed of three principal ethnic groups: the Ilocanos, Tagalogs and Zambals.  The name of the province is derived from its earliest inhabitants, the Zambals. They worship spirits called "anitos", thus they were referred to as "Sambali" from the Malay word samba, meaning "to worship". The term was later Hispanicized to "Zambal".
