🌍 The world isn't aging evenly.

New commentary from our Director Prof. Andy Tatem shows how national averages can hide stark local demographic differences. From Lagos to Kano, and Addis Ababa to Bore, communities within the same country can have very different needs. Better local population data means better planning for schools, healthcare, housing and climate resilience.

WorldPop joined international experts in Jordan to help develop the roadmap for the 2027 Palestine Population and Housing Census. The workshop explored how geospatial technologies, satellite imagery and machine learning can support census delivery in conflict-affected settings while emphasising that full enumeration remains the goal wherever possible.

Geospatial Analysis of Urban Population Model Discrepancies Through Land Use and the Built Environment - A Case Study of Croatia

H/T Olga Bjelotomić Oršulić
“Using official Croatian census data as a reference, [the researchers] analysed three global population datasets across seven Croatian cities to investigate how population allocation differs between built-up and non-built-up areas.
Although the datasets often produced similar population totals, their spatial allocation differed substantially. GHS-POP concentrated over 1 million more inhabitants within built-up areas, while WorldPop allocated approximately 290,000 more inhabitants to non-built-up land-cover classes, demonstrating how similar population totals can mask substantial differences in spatial population patterns.
The question is not only how many people are estimated, but also where the model places them…”

New preprint - the methodology behind the subnational population dataset powering Global 2.

The study harmonised population data from more than 716,000 administrative units across 242 countries and territories, creating estimates from 2010–2030 that underpin our 100m-resolution population maps.

The findings show a world that continues to grow, while demographic change increasingly varies between regions.

MA&amp;UD RECALIBRATES MUNICIPAL WARDS, POPULATION DATA IN KISAN RAIL STATE

Andhra Pradesh MA&UD changes municipal ward member numbers for 87 municipalities and 13 corporations using 2011 population data. See how it affects representation.

The number of elected members in Andhra Pradesh's urban local bodies will now be set by population size, based on the 2011 Census. This means some wards might have more or fewer representatives than before.
