Unified School Districts

Unified School Districts with district and trustee area boundaries, within the extent of Alameda County; boundaries have been updated to show changes for Oakland 2013 redistricting and new Dublin USD Trustee Areas in 2018. Boundaries represent voting districts (i.e., district designation for each address) and therefore may align with parcel boundaries in cases where parcels (and sometimes residences) are divided by the true city/district boundary.本数据集包含阿拉米达县（Alameda County）范围内带有学区边界与受托人区域边界的联合学区（Unified School Districts）相关数据；边界已完成更新，以反映2013年奥克兰（Oakland）选区重划及2018年都柏林联合学区（Dublin USD）受托人区域的调整变化。此类边界代表投票选区（即每个地址对应的学区标识），因此当地块（有时包含住宅）被实际城市或学区边界分割时，边界可能与地块边界相匹配。
