This briefing presents the results of a survey conducted with migrant workers in the construction sector aimed at assessing the implications of the COVID-19 pandemic and related lockdown measures on their lives, jobs, and personal well-being. By developing a better understanding of the changes in the vulnerabilities of migrant construction workers due to COVID-19, learnings from this research can help identify gaps in current pandemic-specific policies and service delivery, as well as inform the implementation of construction worker focused programming for government and private sector stakeholders. The study was conducted via telephone interviews over a 3-month period, resulting in 10,464 completed responses from a pool of construction workers who migrated from the Bundelkhand region to Delhi NCR.
