POVERTY IS THE #1 UN SUSTAINABLE DEVELOPMENT GOAL

The elimination of poverty worldwide is the first of 17 UN Sustainable Development Goals for the year 2030. To track progress towards this goal, we require more frequent and more reliable data on the distribution of poverty than traditional data collection methods can provide. In this project, we propose an approach that combines machine learning with high-resolution satellite imagery to provide new data on socioeconomic indicators of poverty and wealth. Check out the short video below for a quick overview and then read the paper for a more detailed explanation of how it all works.

FINE-GRAINED MAPS OF POVERTY

Using the final model that has been trained on survey data, we can estimate per capita consumption expenditure for any location where we have daytime satellite imagery. This allows us to create fine-grained maps of poverty—here are some that we put together for Nigeria, Uganda, Tanzania, and Malawi.
