Right - but obviously it levels out in older demographics to be pretty constant. I wonder what those numbers look like for subscription sharing across other markets.
Want to put in a quick plug for Sacramento. Great quality of life here, generally great weather (sometimes a little hot in summer, but sunny most of the year), affordable housing with rents between $500 and $1,000 (and affordable to buy a house - still good places available for under $300k), nice neighborhoods, great amenities, bars, restaurants, all that. Good access to awesome outdoors. And really easy to get to the Bay if need be. By Amtrak and BART it takes me 2 hours 12 min to get from downtown Sac to Downtown SF - regardless of traffic (and you can easily work - or drink a beer - on the train). Given how much more affordable it is I am really surprised more folks don't set up shop out here and just head into the bay on occasion / when need be.
