🔥 Do heat adaptation strategies really work?

A study of 1.1 billion devices across 366 Chinese cities shows cooling centres matter - but impacts vary by heat, wealth & age.

🏙️What is a city? The answer changes with the data.

Data quality defines the city. New research shows maps can disagree on what’s urban or rural depending on the population grid underneath.

Journey of a thousand miles begins with one step!

Last week @SyriaUnfpa and partners took a bold first step to explore solutions to strengthen Syria’s #population #data systems. After 14 years of conflict, massive population displacements and limited investment in robust data systems, now is the time to rebuild #Syria statistical system & a culture of data driven planning and decision making. #UNFPA #Syria brought together key national institutions, @UNESCWA and WorldPop in coordination with the Planning and Statistical Commission.

Delighted to have witnessed the beginning of a promising partnership.

🚀 Exciting news! In partnership with the UK’s ONS & funded by FCDO, we're introducing automated mapping tech to Malawi’s National Statistics Office. Streamlining the 2028 #census for fast, cost-efficient, and accurate enumeration.
