ABAG Projections 2007: Glossary of Terms

Jurisdictional Boundary
Tables labeled this way contain data that are displayed according to a city's current boundaries. This does not imply a different type of assumption or an alternative forecast - only a different way to display the same forecast results. See the section on "Jurisdictional Boundaries" for further discussion.

Metropolitan Statistical Area (MSA)
A county or cluster of counties that meet criteria defined by the Office of Management and Budget. These criteria consider population as well as various measures of economic activity.

Sphere of Influence (SOI)
A planning area usually larger than, although sometimes contiguous to, the city's municipal limits. Spheres of Influence are assigned by each county's Local Agency Formation Commission (LAFCO) and typically indicate the probable ultimate boundaries of a city (including areas which may eventually be annexed). See the section on "Subregional Study Areas" for further discussion.

Urban Service Area
Assigned by a county's Local Agency Formation Commission (LAFCO) to indicate an area eligible to receive urban infrastructure (sewer and/or water service) in the short-term.
