South San Francisco lies north of [[San Bruno]] and [[San Francisco International Airport]] in the [[Colma Creek]] valley south of [[Daly City]], [[Colma, California|Colma]], [[Brisbane, California|Brisbane]], and [[San Bruno Mountain]]; east of [[Pacifica, California|Pacifica]] and the hills of the northern [[Santa Cruz Mountains|Coast Range]] lying along the [[San Andreas Fault]]; west of the waters of [[San Francisco Bay]]. Locals often refer to the town as '''South City''', in much the same way that [[San Francisco]] is called "The City."  South San Francisco does not touch on San Francisco, with either [[Brisbane, California|Brisbane]], [[Colma, California|Colma]], or [[Daly City, California|Daly City]] lying between them.

Most of the valley faces east toward San Francisco Bay, affording bay views from higher levels. South San Francisco has mild winters and dry cool summers. The hills to the west shield the eastern parts of the city from some of the fog that prevails in neighboring areas.

The population grew from 4,411 in 1920 to 67,009 in 2014.<ref name="USCensusEst2014">{{cite web|url=https://www.census.gov/popest/data/cities/totals/2014/SUB-EST2014.html|title=Annual Estimates of the Resident Population for Incorporated Places: April 1, 2010 to July 1, 2014|access-date=June 4, 2015|url-status=dead|archive-url=https://web.archive.org/web/20150523034651/https://www.census.gov/popest/data/cities/totals/2014/SUB-EST2014.html|archive-date=May 23, 2015}}</ref>  It has tripled since World War II with the opening of such subdivisions as Buri Buri, Winston Manor and Westborough on the slopes west of El Camino;

The city is particularly noted for the [[South San Francisco hillside sign]] on Sign Hill, which rises to the north of the city, with large white letters that proclaim "South San Francisco, The Industrial City". The sign, a tribute to the city's industrial past, is listed on the [[National Register of Historic Places listings in San Mateo County, California|National Register of Historic Places]].<ref name="nrhp">{{cite web|url={{NRHP url|id=96000761}}|title=National Register of Historic Places Continuation Sheet|work=National Park Service|access-date=April 2, 2013}}</ref>
