The Office of Demographics provides mapping services to Senators and their staffs. Mapping is a useful tool in analyzing and displaying data and can aid in illustrating information in colorful, innovative ways.  Demographics has a library of data sets including legislative boundaries, schools, census tracts, counties, hospitals, highways and much more.

For instance, Demographics has prepared district maps showing the districts represented in California by each of the 40 members of the California State Senate.
