This article is concerned with the measurement of the effect of a year of education on individual income in rural South Vietnam. Data from the 1964 Rural Income and Expenditure Sample Survey of South Vietnam are analyzed with a multiple regression model to detect the effect of education on individual income over-all and by occupation. The regression results show that education has a significant positive effect on individual income despite the generally low level of educational attainment among the rural South Vietnamese. Although the exact rate of return on investment in education cannot be computed because of lack of cost data, the evidence presented suggests that additional investment in literacy education probably would be economically justified.
