In Cambodia, especially in rural areas, few people attended school. Many of these individuals never learned to read or write in Cambodian. Schools were located in the cities, and were unavailable for those without money for tuition, books, supplies and transportation. Most of Seattle's Cambodians are from rural Cambodia where they worked as farmers. Many arrived unable to read or write their language; some are now learning these skills in small groups. Some more fortunate individuals attended formal education in Cambodia, and worked in teaching or other professional fields before coming here. These few individuals also learned some English through private instruction and have been able to find employment in well paying jobs. A few Cambodians have been able to establish their own businesses including restaurants, grocery stores and jewelry stores. However, because of language barriers and lack of education many Cambodians are unemployed and are receiving public assistance. Those who are employed often work as janitors, restaurant workers, or other low paying jobs. They frequently need to work two or even three jobs to make enough money to support themselves.
