From the provided data regarding the Gini coefficients of Sweden and Zambia, we can make the following assumption:
Income is distributed more evenly in Sweden.
The Gini coefficient is a measure of income inequality, where a lower Gini coefficient indicates a more equal distribution of income. Since Sweden has a Gini coefficient of 30% (indicating more equality), and Zambia has a Gini coefficient of 60% (indicating greater inequality), we can conclude that income is distributed more evenly in Sweden.
While the other options may be generally true (such as Sweden having a higher income per capita or being more developed), those conclusions cannot be definitively drawn solely based on the Gini coefficient data provided.
