Numeracy refers to the ability to use numbers, including converting percentages (e.g., 10%) into absolute frequencies (e.g., 1 in 10). Studies have suggested that numeracy is correlated to financial outcomes, suggesting its relevance to financial decisions. However, almost all research on numeracy has been conducted in high-income countries in Europe and North America. Our analyses suggest that low numeracy is much more common in low-income countries, thus potentially threatening the financial well-being of the world's poorest. We analyzed data from the Lloyd's Register Foundation World Risk Poll, which assessed basic numeracy in 141 countries, including 21 low-income, 34 lower middle income, 43 upper middle income, and 43 high-income countries. Numeracy was associated with being among the poorest 20% of one's country, and with difficulty living on one's income, even after accounting for income, education, and demographics. These findings underscore the importance of worldwide numeracy education.
计算能力是指使用数字的能力，包括将百分比（例如 10%）转换为绝对频率（例如 1/10）。研究表明，计算能力与财务结果相关，表明其与财务决策有关。然而，几乎所有关于计算能力的研究都是在欧洲和北美的高收入国家进行的。我们的分析表明，在低收入国家，计算能力较低的情况更为普遍，这可能会威胁到世界上最贫困人口的财务福祉。我们分析了劳氏船级社基金会世界风险调查的数据，该调查评估了 141 个国家的基本计算能力，其中包括 21 个低收入国家、34 个中下收入国家、43 个中上收入国家和 43 个高收入国家。计算能力与一个国家中最贫困的 20%有关，并且即使在考虑收入、教育和人口统计数据后，也与难以维持生计有关。这些发现强调了全球计算能力教育的重要性。
