Explanation:

• The 2020 global Multidimensional Poverty Index (MPI) was recently released by the Oxford Poverty and Human Development Initiative (OPHI) and the United Nations Development Programme (UNDP).
• It is an international measure of acute multidimensional poverty covering over 100 developing countries.
• 2020 marks the ten year anniversary since the global MPI was first launched in partnership with the UNDP’s Human Development Report Office (HDRO).

Key Findings of the report

• Around 1.3 billion people are still living in multidimensional poverty.
• Children show higher rates of multidimensional poverty. Half of multidimensionally poor people (644 million) are children under age 18. One in three children is poor compared with one in six adults.
• About 84 % of multidimensionally poor people live in Sub-Saharan Africa (558 million) and South Asia (530 million).
• Four countries halved their MPI value. India (2005/06–2015/16) did so nationally and among children and had the biggest reduction in the number of multidimensionally poor people (over 270 million).

Hence only statements 2&3 are correct.
