DC Econ: The Paradox of Household Income

Since less people get married there are more total households to count for data. Furthermore, since those households only have one provider, it seems as if the average income per household is dipping even if the average income per person is increasing.
It could mean that. Measuring the economy needs to also include family structures to accurately portray data.
I think this question might be worded wrong because the video actually suggests the opposite. Since less people are married the average income per household drops. This causes a poor performance in the economy.
I think both are right when looked at in context. You have to understand the 4 percent and the 25 percent and how those numbers were fully calculated to understand what they mean.
