About Our Data

Current Data - According to US census, over 17% of Californians change residence each year. To keep up with rapid changes in the voter file, our county voter files are updated an average of more than five times per year. This ensures that campaigns can contact recent registrants and will not waste time trying to contact voters who have moved or died.


Accurate Data - With the expressed goal to provide the highest quality data to our customers, PDI became the first company to offer many services that are taken for granted today. We were the first firm to provide access to voter history, outside telephone matches, assessor-homeowner matches, ethnic surname matches and National Change of Address data as standard products. We continue to maintain California's most comprehensive voter database with enhanced voter history, telephone numbers, assessor-homeowner identification, email addresses, ethnic surname identification, and birthplace information.


Simple to Use - From count reports to data products, PDI provides quality information that is easy to use and understand. The-PDI.com, our online management system, is a highly sophisticated voter data management tool for campaigns of every size and level of expertise.
