California Dioceses 1922-2005

Between 1922 and 2005, California's population increased more than tenfold from 3.4 million to 36 million. In order to cope administratively with this growth, California's 4 dioceses were divided and redivided over the years, so that by 2005, approximately 10 million California Catholics were organized in 12 dioceses.

One result of these demographic and administrative changes has been that the responsibility for abusive priests has shifted as the dioceses have multiplied. A priest who began offending in Los Angeles might continue his crimes as an Orange priest, for example. The creation of new dioceses also afforded the older dioceses an opportunity to off-load offenders, as seems to have happened when San Bernardino was created from San Diego. When personnel files are scattered, the chances of confusion and concealment increase as well.

Below we provide a series of maps that show how the California dioceses have changed over the years. Scroll through them or click from view to view.
