Abandoned shipyard, Richmond Ca.

At the outset of WWII four shipyards were built along the Richmond waterfront, employing thousands of workers, many recruited from all over the United States, including many African-Americans and women entering the workforce for the first time....Once the war ended the shipyard workers were no longer needed, beginning a decades-long population decline. The Census listed 99,545 residents in 1950. By 1960 much of the temporary housing built for the shipyard workers was torn down, and the population dropped to about 71,000.
