Anyhow, I have clearly been sleeping on my own hometown.

My entire life I have considered the cities and towns part of the old Pacific Bell Oakland phone book to be the immediate Oakland-Berkeley 'Area'. I know there's a lot of building, but
City----------------2020---------2010-------10-Year Growth--
Oakland.............440,031.....390,724...+49,922...+12.8%
Berkeley ...........124,321......112,514...+11,741...+10.4%
San Leandro.......91,008........84,950.....+6,058.....+7.1%
Alameda.............78,280........73,812.....+4,468.....+6.0%

Total.................862,881.....775,740...+87,141...+11.2%
Oh, and this covers about 104 sq miles.
I think the area might actually surpass the city sooner than later..
