Community Host model

A four-step method for recruiting globally representative participants: random location lottery using population data, recruiting local community hosts, having hosts recruit diverse local candidates, then using sortition with stratification to select final participants. The 2021 Global Assembly used a NASA population density database to select 100 random points globally, then worked with trusted local organizations to recruit 4-6 candidates per location through street conversations and door-knocking. The method achieved proportional representation by gender, age, geography, climate attitudes, and education. In-country partners worked directly with members of the assembly to provide them a safe place to work, a computer, internet connection, and technical assistance
