Notes

  1. Resident Population consists of those who live in housing units in the same area covered by Total Population. It is equal to "Total Population in Households".
  2. Group Quarters Population includes persons in student dormitories, military barracks, prisons and health care institutions. Group Quarters and Resident Populations sum to Total Population.
  3. Single-family Housing Units (SfHUs) only include detached dwellings.
  4. Multiple-family Housing Units (MfHUs)include apartment buildings (both for rent and condominiums), duplexes, artist-in-residence lofts, and attached single-family housing units.
  5. Nonsingle-family Housing Units (NsHUs) add mobile homes, boats, and other living quarters to MfHUs. Its sum with SfHUs yield all living quarters for residents of the census tract. This value is consistent with the definitions used by the Southern California Association of Governments (SCAG) and the California Department of Finance (DoF).
  6. The persons who occupy a housing unit are defined as a HOUSEHOLD. Households may consist of one person, one or more families, or a group of unrelated persons.
