Background: Rural out-migration is a common phenomenon in Ethiopia. Several studies explain migration as the outcome of an individual utility-maximizing decision. This perspective ignores the diversity of migration types and inadequately explains migration in the wider context of mutual and interdependent risk-sharing strategies of household members in response to locational advantages and disadvantages. Objective: The main objective of this study is to examine households' choice of short-term and long-term migration and its underlying determinants in different locational contexts. Methods: Based on the household-centred New Economics Labour Migration (NELM) framework, we conducted quasi-longitudinal and context-specific structured interviews with 553 randomly selected households in four rural study sites in north-west Ethiopia. The determinants of household migration decisions on the one hand and the variables explaining decisions for short-term and long-term migration were analysed in a binary logistic regression and a multinomial logistic regression. Results: The results show a positive relation between migration decisions and household variables such as a higher education status, perceived food insufficiency, female household heads, household-head age, household size, and number of economic activities. Beyond the NELM framework, location in different livelihood zones is also significant in diverging migration strategies. Short-term migration is very much driven by locational advantages and food insufficiency. The propensity for long-term migration significantly increases for households with a higher educational level, but declines with a rising number of dependent household members. Contribution: We contribute to the discussion of ambiguous determinants of migration and provide more differentiated insight into short-term and long-term migration decisions. Besides strong support for the NELM framework, we highlight the relevance of education for long-term migration and locational meso-level factors for short-term migration.
