<p>The failures of the formal social protection system in Nigeria have made the extended family a widely relied-upon actor in the social security of Nigerians. Despite this enormous value, the extended family’s importance, contributions, and roles in the welfare of Nigerians, especially after the COVID-19 pandemic, are not always highlighted. Filling this recognition gap triggers this study. Specifically, this study focuses on extended family welfare care, intergenerational care flow patterns such as traditional downward, reversed upward, sandwich, and horizontal, and the pattern of care provision from the extended family to women-led households. Using a cross-sectional quantitative methodology, the study surveys households in Warri, an oil-rich region in Nigeria. Findings suggest that a large population of Nigerians rely on an extended family welfare system, with the intergenerational care flow pattern being sandwiched, where an adult simultaneously supports both younger and older relatives.</p>
