In May 2020 UNICEF and UNFPA jointly commissioned the Families on the Edge study to explore the impact of the COVID-19 crisis on women and children in low income urban families in Malaysia. This report is the first in a series of reports under the Families on the Edge project and describes the immediate socio-economic impact of the COVID-19 crisis on a group of 500 families with children in Kuala Lumpur’s low-cost flats, as well as preliminary insights on the relevance, adequacy and accessibility of key COVID-19 mitigation policies and other critical social services for this particularly vulnerable group. Future reports are expected to monitor the extent to which these families recover and offer critical insights for the general public and policymakers as Malaysia aims to ‘build-back-better’
