Disruptive Country Ranking: The Baby Money Index (BMI) Emerges
2024-12-15
An economics article introduces a new country ranking metric—the Baby Money Index (BMI), which multiplies per capita Gross National Income by the square of the fertility rate. Unlike the traditional Human Development Index (HDI), the BMI focuses more on the long-term impact of population growth on the economy. The article points out that high income and high fertility are difficult to achieve simultaneously; many oil-rich or tax-haven countries top the list, while some developed countries rank lower due to low fertility rates. The United States outperforms any country with a population over 40 million, including the entire G12, due to its high BMI.
