This is from 2013. It hasn't gotten better. Their median for the city I live in is $2395 (and for reference, I'm an hour+ drive from San Francisco; ~2 hours by train).
Rents around me have definitely been going up, even if they're not at $2400. And that's for studios/1 bedrooms. If I were to move into the exact apartment I have now, the rent on the lease would be a few hundred dollars more than what I'm already paying (despite the fact that they've been bumping my rent up as much as they can).
Yes, there are low-rent areas. But a lot of people don't have the option to live in them.
My friend is fond of telling me I could get a sweet 1000sqft loft in downtown Houston for $1200/mo or so. Or a regular apartment for half that.
Of course, to me, not living in Texas is worth the extra thousand dollars a month
I get the feeling that people are confusing the rents in extremely desirable neighborhoods with the rents you must pay to be in the city at all.
Unless you live in NY, SF (/me waves!), or DC, that number is grossly out of touch with the actual costs of rent in the United States.
