Thanks for the really good question.
The answer is that there are different kinds of programs that require different sorts of affordability. If we're looking at a supply program as opposed to a deeply affordable program, it might be appropriate to look at a different measure.
Sometimes we will look at affordability measures related to the average renter, and sometimes we'll look at affordability measures related to the average household income. It really depends on what kind of program we're looking at. If it's a supply program, it may be more appropriate to look at the renter. If it's a deeply affordable program, we're more likely to look at the income of a household as we're establishing those targets.
