The COVID-19 pandemic caused significant income and employment drops in low- and middle-income countries. Many households faced food insecurity and economic hardship, with insufficient support to maintain living standards.
Area of Science:
- Socioeconomic impacts of global health crises
- Economic resilience in developing nations
- Quantitative social science research
Background:
- Limited quantitative data exists on the economic effects of the COVID-19 pandemic in low- and middle-income countries.
- Official statistics often fail to capture informal sectors and subsistence agriculture prevalent in these regions.
Purpose of the Study:
- To provide systematic quantitative evidence on the economic conditions of households in low- and middle-income countries during the COVID-19 pandemic.
- To assess the impact on employment, income, food security, and living standards.
Main Methods:
- Conducted 16 original household surveys across nine countries in Africa, Asia, and Latin America.
- Collected data from over 30,000 respondents regarding employment, income, and coping strategies.
- Analyzed economic conditions and household vulnerability starting March 2020.
Main Results:
- Documented widespread declines in employment and income across all surveyed countries beginning March 2020.
- Reported that 8% to 87% of households experienced an income drop (median 68%).
- Found household coping strategies and government aid insufficient to prevent food insecurity and economic distress.
Conclusions:
- The COVID-19 pandemic severely impacted economic stability in low- and middle-income countries, leading to widespread food insecurity.
- Existing support systems were inadequate to mitigate the crisis's immediate economic fallout.
- Persistent adverse effects are anticipated, particularly for vulnerable populations like children.
