The housing shortage is a grim fact of life around the Bay Area — but sometimes the numbers can boggle the minds of even the most hardened cynics.

So it was with a map put out by the Metropolitan Transportation Commission late last month and making the rounds on Twitter this week. The map explores how long it would take various cities around the Bay Area to meet their 2040 housing goals if they continued building at the annualized rate they hit from 2010 to 2017. It's not pretty. See how Bay Area cities are looking in the gallery above.

The housing goals are set by the Association of Bay Area Governments, a group created by Bay Area governments to meet their research and planning needs, as part of a regional plan to accommodate population and employment growth. They're based on the projected distribution of growth around the region.

By 2040, the population is expected to rise to 9.6 million and employment to 4.7 million.

"This is a regional blueprint for growth," MTC planner Matt Maloney told the Chronicle last year. "It's certainly not meant to usurp local control."

"Every single county is over-performing its job forecast, some by massive amounts, and every single county is under-performing its housing forecast, almost all by a wide margin," MTC director Steve Heminger said in his report to the Association of Bay Area Governments executive board last month.

San Francisco would be 23 years behind schedule if it kept building at its 2010-2017 rate, meeting its 2040 target in 2063. But that's nothing compared to some other cities around the Bay Area.

There are a few bright spots, most of them a ways inland — Gilroy, Brentwood, Dublin and Fairfield are all ahead of schedule for housing production, according to the MTC — but many more of the estimates are sobering.

Oakland needs another couple centuries to meet the 2040 goal; It's projected to reach its 2040 housing target in 2295. Emeryville would need until 2211, Richmond until 2458.

And at the rate construction was going from 2010 to 2017, Concord would have to keep building for 966 years to meet the 2040 goal. Let's hope it's not all underwater by then.
