    Poverty and Shared Prosperity 2020: Reversals of Fortune

    October 2020
    The report presents new estimates of COVID-19’s impacts on global poverty and inequality. Harnessing fresh data from frontline surveys and economic simulations, it shows that pandemic-related job losses and deprivation worldwide are hitting already-poor and vulnerable people hard, while also partly changing the profile of global poverty by creating millions of “new poor.” Furthermore, the report breaks ground by jointly analyzing three factors whose convergence is driving the current crisis and will extend its impact into the future: the COVID-19 pandemic, armed conflict, and climate change.
