L2 VoterMapping

L2 provides a voter file for the United States. To create this file, L2 processes registered voter data on an ongoing basis for all 50 states and the District of Columbia, with refreshes of the underlying state voter data typically at least every six months and refreshes of telephone numbers and National Change of Address processing approximately every 30 to 60 days. These data are standardized and enhanced with proprietary commercial data and modeling codes and consist of approximately 185,000,000 records nationwide forming the L2 Voter List

L2 为美国地区提供选民档案文件。为构建该文件，L2 持续对全美50个州及哥伦比亚特区的注册选民数据进行处理：其底层州级选民数据通常至少每6个月刷新一次，电话号码数据与国家地址变更（National Change of Address）流程则约每30至60天更新一次。此类数据已完成标准化处理，并通过专有商业数据与建模编码进行增强优化，全国范围内共计约1.85亿条记录，构成L2选民名单（L2 Voter List）。
