The number of people living in extreme poverty is projected to increase

David Nash just published a response to the Our World in Data blog post which seems like an important read. 

I think the upshot is largely the same in any case: it is important to stimulate economic development in the poorest sub-Saharan African countries where GDP growth has been stagnant for a long time.

This is very important. Thank you for sharing. I didn't realize the situation was this dire. I am very interested in discussing potential interventions to stimulate economic growth in the poorest countries (since that seems the main/only way to help). 

This chart from the post makes the point even more clearly:
 

Our World in Data explains:

What is different today is that the majority of the world’s poorest people are stuck in economies that have been stagnating for a long time. Consider the case of Madagascar. In the long run, the country has not seen any growth at all: GDP per capita in Madagascar is about the same today as it was in 1950. As a consequence, the number of people in extreme poverty increased in line with the country’s population growth. 

And they continue:

The situation is similar in other countries, as the chart below shows: in the Democratic Republic of Congo, Mozambique, Malawi, Burundi, and the Central African Republic, more than half of the population lives in extreme poverty. As their economies have stagnated, the deep poverty that most people live in has remained largely unchanged for decades.

I think when people say it is rapidly decreasing they may often mean that the the % of the world's population living in extreme poverty is declining over time, rather than that the total number of people living in extreme poverty is going down?

East Africa seems to contain several exceptions to this general stagnation in SSA for the past two decades or so. Might be useful to compare and see what might be replicated elsewhere.

If only the government in sub Sahara Africa countries prioritize citizens welfare as top priority . In Nigeria my country the minimum wage basically enough to fend for yourself for a country with rich natural resources
