Immigrants have been assimilated into the Thai population throughout the country's long history. Many were skilled people – dancers, writers, painters, sculptors, musicians and architects, and they helped to enrich the already existing culture.
There is a rich ethnic diversity in Thailand's population – Thai, Mon, Khymer, Laotian, Chinese, Malay, Persian and Indian stock – and so there is no typical Thai face or physical type. People can be short, tall, dark-skinned or light-skinned.
About 80 percent of Thais are involved in agriculture which has an effect on many of the religious ceremonies and festivals of the country.
