Statistical Interpretation of Values

We have two people:

  1. Person One: earns 100 US dollars per month, spends 50 on rent, and 50 on other stuff

  • Person Two: earns 100 US dollars per month, spends 50 on food, saves the rest, does not spend anything on rent because he owns a house.

A user visits my website and wants to know what percent of the average American's income is spent on rent. Which of the below approaches should I follow and why:

  • Approach A: calculate the average of rent for everyone whether they rent or own a house: Percent Spent on Rent (Percent A) = ((50 + 0) / (100 + 100)) * 100 = 25%
  • Approach B: calculate the average of rent only the people who actually rent houses only: Percent Spent on Rent (Percent B) = (50 / 100) * 100 = 50%

I know what each value means and how it is read:

Percent A reads as:"25% of all income in the US is spent on rent"

Percent B reads as:"50% of income of the people who rent houses is spent on rent"

My question: which value is more meaningful to a person viewing such a report (renting or owning a house)? Which value makes more sense? Does percent A have any value? Does it mean anything?
