The primary aim of this ILO study is to provide updated estimates of the financing gap to attain universal coverage for social protection floors. This estimation encompasses 133 low- and middle-income countries, and includes five income security guarantees (for children, persons with severe disabilities, mothers of newborns, older persons and the unemployed), together with essential health care.
