Comment: This article was published in September 2019... Welcome to 2020! With its near global lockdown that accelerated the impending world economic crisis.
We make these claims based on a classification of households into those in extreme poverty (households spending below $1.90 per person per day) and those in the middle class (households spending $11-110 per day per person in 2011 purchasing power parity, or PPP). Two other groups round out our classification: vulnerable households fall between those in poverty and the middle class; and those who are at the top of the distribution who are classified as "rich."
