The decision of whether to migrate or not is one of many important decisions that young men and women make throughout the developing world. In this webinar, we will discuss determinants of internal migration by youth within five different countries (Bangladesh, Indonesia, Nigeria, Pakistan, and Tanzania) using recently collected data, investigating both broad and specific hypotheses related to migration (such as whether and how migrants are positively selected on specific human capital characteristics). A key finding is that individual characteristics, like schooling, are more important determinants of migration than household characteristics. We also find little evidence that credit constraints or relative deprivation are correlated with migration at a nationally representative level, holding other things constant. This is important because previous studies, which were carried out in smaller sub-regions of countries, had found those credit constraints to be important. The webinar concludes with implications for policy in relation to migration, youth and employment, and rural development.
