Yemen has faced significant insecurity since 2014, leading to widespread internal displacement and challenges in tracking population changes.
Researchers reconstructed Yemen's population data from June 2014 to September 2021, using various methods to account for births, deaths, and internal migration, despite inadequate vital event registration.
The study estimated Yemen's population growth from 26.3 million to 31.1 million, revealing that 10 to 14 million people may have been displaced during peak conflict years, highlighting the need for better data collection methods for future assessments.
