1 . COVID-19 shutdowns forced people out of work and pushed tens of millions into poverty worldwide. Governments tried hard to provide aid. It was easy in a small country, but difficult for a country with large population and vast rural areas.
Researchers have been finding ways to identify areas of wealth and poverty in satellite images. Through some satellite data and aerial images of one town or another, you can sort of tell whether it’s wealthy or not. Wealthier homes tend to have metal roofs while poor homes tend to have thatched roofs. Wealthier neighborhoods have paved roads and bigger plots of lands, more spaced out.
The researchers use the system to identify about 60,000 people to receive benefits. The advantage of the satellite imagery and phone data approach is that it’s extremely fast and very convenient.
