Based on prior knowledge, marital status can be a relevant feature when determining if a person earns more than $50,000 per year. Generally, individuals who are married (either civil or Armed Forces) tend to have higher incomes compared to those who are not married or divorced. Therefore, it is likely that the categories "Married-civ-spouse" and "Married-AF-spouse" will have a higher proportion of individuals earning more than $50,000 per year.

However, it is important to note that this relationship is not universally true for all individuals. There can be exceptions, and other factors may also contribute to a person's income level. 

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

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

In this dictionary, the categories of "marital-status" that are more likely to have individuals earning less than $50,000 per year are listed under the key "no", and the categories more likely to have individuals earning more than $50,000 per year are listed under the key "yes".
