A retrospective longitudinal study was conducted in Meskan and Mareko Woreda to describe the magnitude, patterns and differentials of internal migration in 9 PAs and 1 UDA sampled using probability proportionate to size. Data on variables of population mobility were collected by BRHP using monthly household visits for the period 1987-1994. In addition, in-depth interviews with key informants, focus group discussions & observation were conducted in the study sites. Results showed that during the 1987-1994 there was a total of 18,426 moves, of which 9,610 (52%) were in-migrants and 8,816 (48%) were out-migrants. The sex distribution of both in- and out-migrants demonstrate that females outnumber males. The age group with the highest percentage of internal migrants is in the range of 15-24 years. The observed rates per 1000 mid-year population are 36.0 and 33.1 for in- and out-migration respectively while the net-migration was 2.9 per 1000 mid-year population. It is observed that both in- and out-migrants are in the active and productive age group. The pattern of population movement is mainly seasonal. Employment & marriage appear to be the main motives for the population movement in the area while education is also becoming important. The pattern of age/sex selectivity of migration has important public health implications, in that they affect the relative size of important target group, such as children 0-4 & female 15-24 years. Further detailed studies to fully understand migration streams, determinants & consequences are essentialenInternal MigrationThesis
