Book excerpt: In 2018, the World Bank launched the Human Capital Index (HCI), which is designed to highlight how improvements in current health and education outcomes will shape the productivity of the next generation of workers. The HCI measures the amount of human capital that a child born today can expect to have by age 18, in view of the risks of poor education and poor health that prevail in the country where she or he was born. This update presents the ECA- HCI, which extends the HCI in two dimensions to make it more relevant for countries in Europe and Central Asia. First, the extension includes quality-adjusted years of tertiary education, in addition to basic education. Second, going beyond the child stunting and adult survival rates, the ECA-HCI proxies health status by including risk factors such as obesity, smoking, and heavy drinking, which are prevalent in the region. This exercise reveals that a child born today in the average country in the region would be only half as productive as he/she could have been with full tertiary education and full health.
