The share of people living in absolute poverty in North Korea is higher than once thought, making it one of the poorest countries on Earth, new research from Vienna University of Economics and Business reveals.

According to Jesus Crespo Cuaresma, Professor of Macroeconomics, the share of people living in absolute  in North Korea in 2018 can be estimated at around 60% of the population, which equates to roughly 15 million people. GDP per capita is estimated to be around $790, an  that would be among the lowest in the world.

Absolute poverty is when  is below a certain level, which makes it impossible for the person or family to meet basic needs of life including food, shelter, safe drinking water, education, healthcare, etc.

Despite there being virtually no existing information or data on North Korean income and , Professor Crespo Cuaresma and his team have been able to establish estimates using satellite data. Harnessing data from innovative satellite imagery taken at night, Crespo Cuaresma was able to gauge the poverty levels of particular regions of North Korea based on the amount of light each area emitted.

Nightlight  can be used in this way to estimate income at a detailed level as the brightness of an area often correlates with consumption and production activities.

Combining nightlight data with estimates of North Korean GDP, the researchers were able to estimate that poverty levels were significantly higher than previous estimations which suggested the share of people living below the poverty line to be closer to 40% of the population.
