worldbank.org (16.11.2021) While health indicators and macroeconomic data are essential for addressing the fundamentals of the COVID-19 crisis, countervailing policies need detailed information on the mechanisms through which the pandemic affects human capital, livelihoods, and welfare. This is especially important in Nigeria because the pandemic threatens to compound the country’s high levels of poverty: even before COVID-19, around 4 in 10 Nigerians lived below the national poverty line, and multidimensional poverty was even more widespread. In Nigeria, this kind of detailed analysis is made possible by high-frequency data collected during the pandemic through the Nigeria COVID-19 National Longitudinal Phone Survey (NLPS). This nationally-representative survey is distinctive in capturing key socioeconomic information from households for 12 consecutive rounds between April 2020 and April 2021: few other developing countries with which the World Bank has worked on phone surveys have such extensive data. A new report – COVID-19 in Nigeria: Frontline Data and Pathways for Policy – uses the NLPS to examine how the COVID-19 crisis has been affecting the human capital, livelihoods, and welfare of Nigerian households.
