N2 - The spatial distribution and growth of human populations have been overlooked by current debates concerning the impact of rural-urban migration for forest conservation in tropical countries. We investigated human settlement and population change in the Brazilian Amazon, combining government census data with field surveys along rivers. Rural populations were clustered and growing within 300 km of urban centers, whereas depopulation and land abandonment dominated farther from towns. The permanently inhabited extent of rivers contracted by 33 +/- 8 SE% in recent decades, and households farther upriver were more likely to be considering rural-urban migration.
