Preparing for the Aging Population

The aging of the Baby Boomer population is a priority concern for San Mateo County.

Baby Boomers, people born between 1946 and 1964, are considered to be the largest generational cohort in recent history. Although projection figures exist, none have taken the uniqueness of San Mateo County into account or provide the level of detail necessary to inform local planning and policy decisions. Along with this demographic shift, service needs in the areas of health, housing and transportation are expected to change along with this demographic shift.

In order to adequately plan for coordinated services, San Mateo County seeks to accurately predict this population’s future characteristics, including racial/ethnic composition, income distribution, housing preferences, and disability rates. To meet these objectives, representatives from the San Mateo County Health System, Department of Housing, San Mateo Transit District, Health Plan of San Mateo, and the Commission on Aging collaborated to create a demographic projection model to prepare for the years 2020 and 2030.

This model was adopted by the San Mateo County Board of Supervisors in October 2007. Special attention was given to people born between 1931 and 1964 because they will represent the majority of the population over 65 in the years 2020 and 2030. The Lewin Group was hired to undertake this endeavor.
