    Low Numeracy is Associated with Poor Financial Well-being Around the World
    (PLOS, 2021-11-22) Slovic, Paul; Bruine de Bruin, Wandi
    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.

    People who are bad with numbers often find it harder to make ends meet – even if they are not poor
    (The Conversation, 2021-12-20) Bruine de Bruin, Wandi; Slovic, Paul
    People who are bad with numbers are more likely to experience financial difficulties than people who are good with numbers. That’s according to our analyses of the Lloyd’s Register Foundation World Risk Poll. In this World Risk Poll, people from 141 countries were asked if 10% was bigger than, smaller than or the same as 1 out of 10. Participants were said to be bad with numbers if they did not provide the correct answer – which is that 10% is the same as 1 out of 10. Our analyses found that people who answered incorrectly are often among the poorest in their country. Prior studies in the United States, United Kingdom, the Netherlands and Peru had also found that people who are bad with numbers are financially worse off. But our analyses of the World Risk Poll further showed that people who are bad with numbers find it harder to make ends meet, even if they are not poor.
