Overview
The model of the world economy is built on three layers of geographical division.
1. The world is divided into 202 countries.
2. Countries are divided into 2,311 administrative (level one) units.
3. Administrative units are divided into pixels.
Country and administrative unit maps are compiled from GADM.org.
Country and administrative unit maps are compiled from GADM.org.
Below, we summarize the number of administrative units for each country.
Country and administrative unit maps are compiled from GADM.org.
Countries are aggregated into continents according to the Atlas of Sustainable Development Goals, published by the World Bank:

Pixels are areas equivalent to 2.5 arc minutes squared, which corresponds to approximately 5x5 km squares on the Equator. Pixels constitute the main building blocks of the world economy model, and are defined by initial allocation of all types of individuals, production technology, climate conditions and future climate shocks. Each pixel hosts one production sector (agriculture, industry or services), and offers specific wage rates for all workers at four education levels. Thanks to this detailed resolution, it is possible to precisely describe the spatial distribution of human settlement, economic activity and climate heterogeneity that (co-interacting) fundamentally affect the future patterns of migration at all geographical scales.
