The FINANCIAL -- New World Bank research released gives policymakers compelling evidence that delivering better outcomes in children’s health and learning can significantly boost the incomes of people—and of countries—with returns far into the future.
A Human Capital Index, launched at the World Bank-IMF Annual Meetings, shows that 56 percent of children born today across the world will lose more than half their potential lifetime earnings because governments are not currently making effective investments in their people to ensure a healthy, educated, and resilient population ready for the workplace of the future.
Human capital—the knowledge, skills, and health that people accumulate over their lives—has been a key factor behind the sustained economic growth and poverty reduction rates of many countries in the 20th century, especially East Asia.
The Human Capital Index measures the amount of human capital that a child born today can expect to attain by age 18, given the risks of poor health and education that prevail in the country where he or she lives. The Index measures each country’s distance to the frontier of complete education and full health for a child born today.
The measure includes:
Survival – Will children born today survive to school age?
School – How much schooling will they complete and how much will they learn?
Health – Will they leave school in good health, ready for further learning and/or work as adults?
The HCI reflects the productivity as a future worker of a child born today, compared with what it could be if he or she had full health and complete, high-quality education, on a scale from zero to one, with 1 as the best possible score. A country score of 0.5, for example, means that individuals – and the country as a whole – are forgoing half their future economic potential. Calculated over 50 years, this translates into deep economic losses: a 1.4 percent annual loss in GDP growth.
The Index ranks where each country is now in terms of productivity of the next generation of workers. In countries like Azerbaijan, Ecuador, Mexico, and Thailand, children born today would be 40 percent more productive as workers in the future if they enjoyed complete education and full health. In countries like Morocco, El Salvador, Tunisia and Kenya, 50 percent more.
Sex-disaggregated data is available for 126 of the Index’s 157 countries. For this subset of countries, both boys’ and girls’ human capital is still far from the frontier of potential human capital accumulation. In most countries, the human capital gap for both boys and girls from the frontier is larger than the gap between boys and girls.
Evidence shows that progress is possible. Poland enacted education reforms between 1990 and 2015, and experienced one of the fastest improvements in PISA scores in OECD countries. Vietnam recently topped the OECD average PISA score. Malawi succeeded in reducing its rate of stunting by nearly 20 percentage points in under two decades. But the index shows much more needs to be done.
The Index is part of the World Bank Group’s Human Capital Project, which recognizes human capital as driver of inclusive growth. In addition to the Index, the Human Capital Project includes a program to strengthen research and measurement on human capital, as well as support to countries to accelerate progress in human capital outcomes.
