popgrid report coverHaving reliable and timely population data can make a life or death difference for individuals facing crises or living in conflict-ridden regions. These data are essential for addressing the above challenges and for critical decision-making and planning. 

We need to know where people are located, what conditions they are facing, what infrastructure is available, and what basic services they can access. When it comes to counting people in hard-to-reach and often hostile environments, there are no silver bullets.

The report aims to narrow this knowledge gap by helping to improve the accessibility and understanding of gridded population datasets for policymakers and other users.
