Title: 0112_SuburbanAreas_2024_05
Author: erika.knight@audubon.org_audubon
Comments:
Subject: To map suburban areas, we used an approach that combines information about the built environment and population density. We created a hemispheric building footprint layer by combining the Google Building Footprints (for Mexico to Argentina) and Microsoft polygon layers (for the US and Canada), converting all to a raster showing percent area of each cell covered by buildings. For the US and Canada, we included all cells with greater than one percent area covered by buildings; for Mexico to Argentina, we included all cells with greater than six percent covered by buildings. We then split the built area into urban versus suburban, where suburban areas were those places where the human population density was less than 1,000 people per square mile (386 people per square kilometer) in 2020 (WorldPop 2020).
