"The Ebb and Flow Report explores the why, who, where, and what at the nexus of water and migration, and the implications for economic development."

This Ebb and Flow: Water, Migration, and Development report is based on an analysis of the largest data set on internal migration ever assembled, covering nearly half a billion people from 189 population censuses in 64 countries from 1960 to 2015. It assesses how rainfall shocks are related to migration relative to other key variables such as age, gender, education, and household size. The report is in two parts. Volume 1 covers water, migration, and development. Volume 2 focuses on water, forced displacement, and conflict in the Middle East and North Africa. This Knowledge Note provides the Key Highlights of the report.
