Finding ways for people to be healthier and better-educated is both a useful goal in itself, and also an investment that increases future economic production. When I find myself worrying, as one does, that the world is falling to pieces, it's useful to remember basic facts: "The world is healthier and more educated than ever. In 1980 only 5 in 10 primary school-age children in low-income countries were enrolled in school. By 2015 this number had increased to 8 in 10. In 1980 only 84 of 100 children reached their fifth birthday, compared with 94 of 100 in 2018. A child born in the developing world in 1980 could expect to live for 52 years. In 2018 this number was 65 years." This is from the start of Chapter 3 of the 2019 World Development Report from the World Bank, which focuses on the

The report contains chapters about technology, jobs, firms, and issues of social protection in an evolving economy. But I found myself drawn to the discussion of what economists call "human capital"--the investments in people that lead to future economic output. This version of the WDR introduces a "Human Capital Index," described in this way (footnotes and references to figures are omitted):
"The new index measures the amount of human capital that a child born in 2018 can expect to attain by age 18 in view of the risks of poor education and poor health that prevail in the country in which she was born. ... It has three components: (1) a measure of whether children survive from birth to school age (age 5); (2) a measure of expected years of quality-adjusted school, which combines information on the quantity and quality of education; and (3) two broad measures of health—stunting rates and adult survival rates."On this figure, the horizontal axis measures countries of the world by per capita GDP. For those not used to reading per capita income levels converted to logarithms (!), $60,000 is equal to about 11. The vertical index scales human capital from zero to one. Here's how countries of the world look:
"The World Bank Group and its partners are developing a comprehensive new database of international student achievement test scores covering around 160 economies to benchmark what children learn. The database harmonizes results from international and regional testing programs so they are comparable. For the first time, learning is measurable in nearly all countries using the same yardstick. The differences in learning are dramatic. Country-level average test scores range from around 600 in the best-performing countries to around 300 in the worst-performing. To put these numbers in perspective, a score of roughly 400 corresponds to a benchmark of minimum proficiency set by the Programme for International Student Assessment (PISA), the largest international testing program. Less than half of students in developing countries meet this standard, compared with 86 percent in advanced economies. In Singapore, 98 percent of students reach the international benchmark for basic proficiency in secondary school; in South Africa, only 26 percent of students meet that standard. Essentially, then, all of Singapore’s secondary school students are prepared for a postsecondary education and the world of work, while almost three-quarters of South Africa’s young people are not."
