How does the MPI respond to the effects of shocks?
Because the standard survey data used to estimate the global MPI measure are collected in differing intervals, the ability to detect changes depends upon the frequency of available data. The MPI will reflect the impacts of shocks as far as these cause children to leave primary education or to become undernourished, or lose adequate housing, for example. If more frequent data are available at the country level, this can be used to seek to capture the effects of larger scale economic and other shocks.
The MPI will be a valuable tool to measure the effects of COVID-19 and how the crisis has affected many of the indicators such as nutrition, school attendance, years of schooling and housing. However, the surveys used for the calculation of the 2021 MPI are all pre-COVID-19 pandemic. Future surveys will help reveling the impact of the pandemic on multidimensional poverty.
