The Da Ra’ang people migrated from Shan and Kachin States in Myanmar as war refugees fleeing political conflicts, and settling down at Nor Lae Village in 1968. When the village became overpopulated and farmland and employment were inadequate, re-migration took place to settle in Chiang Dao District, where farmland was more fertile, geographical aspects were more suitable for settlement, and employment in the agricultural sector was in demand. They settled in Mae Jon, Pang Daeng Nai, Huay Bong, and Pang Daeng Nok Villages respectively. Their migration had no fixed patterns. Migration to Mae Jon Village was direct while that to Pang Daeng Nai Village was forced. Migration to Huay Bong Village was incremental and that to Pang Daeng Nok Village was a replacement. Migration patterns to these villages were different, each with its own pattern because other patterns might be implicit. The most important factors influencing their migration and settlement were physical factors, particularly land for cultivation. From this investigation, it was found that farmland was one of the three most important priorities for the ethnic group to re-migrate to each village, except for those to Pang Daeng Nok Village, where cultural factors were the most important. The economic factor, which was employment, was the second most important factor for the villagers to re-migrate to and re-settle in their respective current villages. Lifestyle and economic change of the villagers could be grouped into three periods. In the first period, light subsistence production was the mainstream practice due to sparse population. The rotation agricultural method with a 3-4-year period of soil surface rehabilitation was a common practice. In the second period, commercial crops, such as sesame and corn, were cultivated and a one-year period of soil surface rehabilitation was conducted. In the third period, incomes from tourism were more systematic. Land was more intensively used and lifestyle was more capitalistic.
