Abstract: "Migration is the act or process of moving from one place to another with the intent of staying at the destination permanently or for a relatively long period of time (1992, Longman). It can also be assumed that people move from one place to another, usually their home place, to work or to settle in another place. As basic factors, migration take place an area where the migrants believe that their opportunity and life circumstances will be better at their destinations than the present location. Nevertheless, if an area where takes place a movement of in-­migration because of positive conditions (pull factors), this will be generally increased the population or human resources. Similarly, if an area where takes place a movement of out-­migration due to negative conditions (push factors), this area will lose their population or human resources. Some time it affects the negative impacts and potential challenges for sustainable socio-­economic development of this area. Therefore, this study is based on some specific areas of Myanmar: Hpa-­an Township, Kayin State and Mrauk-­U Township, Rakhine State where migration process takes place by focusing the question of how and why the people are migrating in these areas. This paper is intended to explore the migration patterns of these are as and to point out the main reasons of push and pull factors for these migrations. To obtain the relevant data, it is analyzed with field observation and in semi-­structured in-­depth interview survey method to the local authorities, experts and local people. Some of the facts from the interview data are assessed by SWOT Analysis to know the strengths, weaknesses, opportunities and threats due to migration. As a result from this study, economic condition is the key factor of the migration for the study areas and that effect on the socioeconomic condition of these areas.".....Paper delivered at the International Conference on Burma/Myanmar Studies: Burma/Myanmar in Transition: Connectivity, Changes and Challenges: University Academic Service Centre (UNISERV), Chiang Mai University, Thailand, 24-­26 July 2015.
