The survey, first spotted by the Economist, tested around 160,000 people of all ages, across all 38 member states. It found that across all OECD member countries, a full 8 percent of college students are reading at the level of a ten-year-old, if not worse. While countries like Germany and France rang in at under 5 percent, countries like Poland, Israel, and the United States blew the curve at 21, 20, and 14 percent, respectively.

The numbers aren’t much better when it comes to math. Across OECD countries, 9 percent of college students do math at or below a ten-year-old level. In Italy, the US, and Slovakia, that figure jumps to over 15 percent — only outdone by Israel, where roughly 21 percent of college students were underachieving at the same low benchmark.
