Election Portions of Precincts

Election precincts have been subdivided into portions to account for slight differences in election ballots within a precinct. All precincts have at least one portion, but precincts with only one portion have not been subdivided, and the portion and the precinct are identical. See Clark County Metadata为适配单个选举分区（election precinct）内部选票的细微差异，现有选举分区已被细分为若干子分区。所有选举分区均至少包含一个子分区，但仅含一个子分区的选举分区未被实际细分，此时该子分区与原选举分区完全一致。详见克拉克县元数据（Clark County Metadata）。
