Sustainability Goals

A community can adapt to changing population dynamics without negatively impacting quality of life or depleting non-renewable natural resources.

Total Population San Mateo County, 2000-2018
  • In January 2018, the county population increased substantially by 3,899 from 2017, a 11% increase compared to the low of 699,277 in 2005.

The size, age, and composition of the population are important indicators for community planning and economic activity. Shifts in the demographic profile such as increased immigration and movement towards younger or older age groups can bring new demands for public services, impact economic growth, and exert pressure on open space or natural resources.

Drivers of Population Change San Mateo County, 2000-2017
  • In 2017, natural increase (number of births minus number of deaths) added 4,081 residents to San Mateo County, 1% lower than the year prior.
  • Net migration is a combination of foreign immigration (legal and unauthorized foreign immigration, as well as residents leaving the county to live abroad), and domestic migration (people moving within the United States to and from San Mateo County). In July 2017, the county added 4,808 residents through foreign immigration and lost 4,496 residents to domestic migration.

Population Growth and Migration, 2017
Projected Population Growth Bay Area Counties, 2018
  • San Mateo County is projected to add approximately 100,471 residents by 2040, while the Bay Area is projected to grow by over 1 million people.
  • Calculations made by the Association of Bay Area Governments (ABAG) and Plan Bay Area project even higher population growth between now and 2040. According to their forecasts, San Mateo County will add 185,000 residents and the Bay Area will grow by 2 million.
  • Planning now for additional housing and transportation to accommodate the region’s growth is essential.

  • As our population ages, the share of residents 65 and older is projected to nearly double. By 2040, nearly one in four county residents is expected to be 65 and older.

  • The composition of the county by race/ethnicity will also change over the next twenty years, with the most pronounced growth expected in the share of total population that is Hispanic/Latino.
