Californians for Population Stabilization (CAPS) works to formulate and advance policies and programs designed to stabilize the population of California at a level which will preserve a good quality of life for all Californians.

CAPS is a non-profit 501(c)(3) organization founded in 1986 and working to preserve California's future through the stabilization of our state's human population. Since nearly all of California's runaway population growth comes from immigration, CAPS focuses largely on this issue: sponsoring public and media awareness campaigns, working with lawmakers to promote more responsible policies, maintaining a growing network of member-activists, and conducting vital research.
