The article discusses the measurement of income inequality, emphasizing the methods proposed by Corrado Gini. Gini acknowledges the work of Mr. Hugh Dalton, who suggests a simple method for measuring economic welfare inequality under the assumption that economic welfare is additive. However, Gini notes that Italian methods, while applicable to various quantitative characteristics, focus on income and wealth inequality without assuming functional relationships. Gini suggests that readers should refer to several papers by Italian authors to understand the applicability and nature of these methods. He mentions papers by E. Czuber, C. Gini, and G. Pietra, which he believes may have been overlooked by Dalton. Gini highlights the importance of laboriousness and applicability of methods to imperfect income statistics. He also discusses the mean difference and its relation to the area of concentration, as well as the relationship between the mean difference and Pareto's α when the distribution follows Pareto's curve. Gini emphasizes the practical utility of the graphical method based on the area of concentration. He also notes the relations between the mean deviation from the arithmetic mean, the mean deviation from the median, and the area of concentration. Gini further discusses the ranges of variation of various indices of variability and the causes of discrepancies between them. Finally, he recommends Dr. Pietra's papers for a deeper understanding of these methods. The article also addresses a discussion on the South African Currency, noting that Professor Cannan's article does not fully cover the provisions of the new South African Reserve Bank Act. Gini points out that the Reserve Bank has specific reserve requirements and a graduated tax on excess circulation, which help prevent over-issuance of banknotes. He concludes that the new bank is likely to maintain its issue on an unexceptional basis.The article discusses the measurement of income inequality, emphasizing the methods proposed by Corrado Gini.
