But they blend in wider Bay Area population stats because this is really about jobs that generate SF payroll tax which gives these employers a tacit say and leverage. Remember if you live in Oakland or Redwood City but are employed in San Francisco city/county, some of your payroll tax is being generated to benefit the city of San Francisco even if you are not a resident there.
That's why SF City is worried about SF based businesses and SF Bay Area workers.
(BTW this is also why cities such as Mountain View and Cupertino want to attract large business campuses like Google and Apple but don't want to build homes - they get more income from growing payroll tax but don't then have to spend more on schools, services etc for a growing population - they shift the burden onto other cities and counties that house those workers as they then have to generate tax revenue from other means)
