Registrar Recorder Congressional Districts (2025)

The US Congressional Districts layer contains polygons for US Congressional Districts. The source for the information in this layer is the Los Angeles County Registrar-Recorder's Precinct Information File (PIF), The boundaries are based on the 2020 Census as provided by the California Secretary of State in 2025, after the passing of Proposition 50 from the special statewide election in November 2025. Where boundaries are defined by streets, water bodies, city boundaries, or other features, those boundaries are copied to the districts layer, so that the boundaries and other layer features are aligned. Last Update: December 2025美国国会选区图层包含美国国会选区的多边形要素。本图层的信息来源为洛杉矶县选民登记与记录办公室的选区信息文件（Precinct Information File, PIF）；其边界以2020年人口普查数据为依据，由加利福尼亚州务卿办公室于2025年发布，相关数据是在2025年11月全州特别选举通过第50号提案后完成编制的。当边界由街道、水体、城市边界或其他地理要素划定之时，相关边界将被复制至该选区图层，以确保图层边界与其他地理要素保持对齐一致。最后更新：2025年12月。
