Based on prior knowledge, marital status can be a good indicator of a person's income. In general, individuals who are married, especially to civilian spouses, tend to have higher incomes compared to those who are never married, widowed, divorced, or separated. However, it is important to note that this relationship may not hold true for all cases, as there can be exceptions.

Based on this analysis, the dictionary can be populated as follows:

```json
{
	"no": ["Never-married", "Widowed", "Divorced", "Separated"],  
	"yes": ["Married-civ-spouse", "Married-spouse-absent", "Married-AF-spouse"]
}
```

In this case, individuals who are never married, widowed, divorced, or separated are more likely to earn less than $50,000 per year, and individuals who are married to civilian spouses, spouses absent, or in the Armed Forces are more likely to earn over $50,000 per year.
