The MPI is said to measure “acute” poverty. Does this differ from “extreme” poverty?

The MPI reflects the multiple deprivations that people face at the same time. We have described the MPI as a measure of “acute” poverty because it reflects overlapping deprivation in basic needs and also to avoid confusion with the World Bank’s measure of “extreme” poverty that captures those living on less than $1.90 (in 2011 $PPP) a day.
