Malays make up just over 50% of Malaysia's population, followed by Chinese (24%), Indians (7%) and the indigenous of Sabah and Sarawak (11%), while the remaining of Orang Asli is only 0.7%. Their population is approximately 148,000. The largest group are the Senois, constituting about 54% of the total Orang Asli population. The Proto-Malays form 43%, and the Semang forming 3%. Thailand is home to roughly 600 Orang Asli, divided between "Mani people" with Thai citizenship, and 300 others in the deep south. At the same time, the number of Orang Asli has been growing steadily for many years. Between 1947 and 1997, the average growth rate averaged at 4% per year. This is largely due to the overall improvement in the quality of life of indigenous people.
