    • Overview

    Abstract

    The Human Capital Index Plus (HCI+) converts health, education, and labor market indicators into a common metric of expected lifetime productivity, measured as the expected contribution to log earnings. The index combines three components:

    Health Component - Captures productivity effects of surviving to working age and achieving adequate early-life physical growth
    Education Component - Aggregates human capital accumulated during formal schooling
    On-the-Job Learning Component - Measures human capital accumulation after age 18 from work experience

    Data for the HCI+ combine harmonized data sources from International data custodians, such as the UN, World Bank, ILO, UNICEF, WHO, JME.
