San Francisco&#x27;s city population density is 6x Austin&#x27;s, according to Wikipedia. Are you sure you&#x27;re comparing apples to apples?<p>And San Francisco&#x27;s metro area has more than double the population with about 85% of the land.<p>People ignore this stuff when talking about the San Francisco. It&#x27;s already pretty dense, compared to the median US city. It&#x27;s just that a LOT of people want to live there, and those people have the money to pay.
