Major Private Employers are defined as privately owned companies employing 500 or more persons at one site. In cases where a company has 500 or more employees at more than one site both are included. An example of this is Pacific Bell that has an office downtown and in Mira Mesa.
The Major Employers layer is part of the Regional Activities Centers Inventory. Regional Activity Centers are locations in the San Diego region that attract large numbers of people on a regular basis. Other layers in the Activity Centers Inventory are Hospitals, Colleges, Schools, Government Centers and Major Attractors (tourist attractions and hotels).
SANDAG consolidated information into the first regional Activity Centers Inventory in 1988. Publications and computer data files from various agencies were used as initial sources for the verification and existence of sites. The San Diego Chamber of Commerce 'Business Referral Directory', and CALTRANS' Commuter Computer file provided information on major private employers and government centers. Other sources included the San Diego Convention & Visitors Bureau, the Hospital Council of San Diego and Imperial Counties, the Naval Facilities Engineering Command, and the telephone book.
Once identified, telephone inquiries were used to collect data and field checks were done to confirm their accuracy. In addition to existing sites the database was expanded to include under construction and proposed sites. After assembling the information into a computer readable file the records were geocoded using the ArcInfo ADDRESSMATCH program. ADDRESSMATCH assigns X-Y coordinates to each record allowing the data to be mapped and used for other GIS applications. The file is updated bi-annually using many of the sources listed above and by monitoring newspaper and magazine articles.
