Abstract

Income diversification not only increases household income and improves the standard of living but also bases policymakers make decisions in the program of poverty reduction to sustainable development. Simpsons Index of Diversity (SID) and the multivariate regression model and the least square estimation (OLS) were used to estimate the degree of income diversification and analyze the factors affecting the diversification of households’ income in Nai lagoon, Ninh Thuan province. The data were collected through direct interviews with 402 households in May 2023 in Nai lagoon. The study results showed that household income per capita is still low (50.316 million VND/ year), and Simpson Index of Diversity (SID = 0.21) is very low. In addition, the result of the regression model also shows that education level, number of laborers, household size, agricultural income, and career affect the diversification of households’ income, in which the household size variable, education level, and number of laborers have the strongest impact on the diversification of households’ income in Nai lagoon, Ninh Thuan province. Thereby, the study proposes policy implications to diversify livelihoods and increase income for local people.
