WI Supervisory Districts (Jan 2026)

Wisconsin County Supervisory districts collected in February 2026. [Attribute Definitions]. U.S. Census Bureau delayed delivery of data so collection was postponed from January to February this year. This data has been collected in regards to state statute 15(4)(br)1. County clerks will transmit municipal, municipal ward, and county supervisory districts in GIS format to LTSB by January 15th and July 15th* per statute 5.15(4)(br)1: "...no later than January 15 and July 15 of each year*, the county clerk shall transmit to the Legislative Technology Services Bureau a report confirming the boundaries of each municipality, ward, and supervisory district in the county together with a map of the county, in an electronic format approved by the Legislative Technology Services Bureau. Each report shall be current to the nearest January 1 or July 1* preceding the date of the report”. Municipal clerks need to notify the county clerk within 5 days of any boundary change per statute 5.15(4)(b): "Within 5 days after adoption or enactment of an ordinance or resolution under this section or any amendment thereto, the municipal clerk shall transmit one copy of the ordinance or resolution or the amendment to the county clerk of each county in which the municipality is contained, accompanied by the list and map specified in par. (a). Each copy shall identify the name of the municipality and the county or counties in which it is located." Municipal data collected in the January collections will be used by LTSB to update municipal boundaries the U.S. Census Bureau’s TIGER database via the Boundary Annexation Survey (BAS). Counties and municipalities are no longer required to submit boundary changes directly to the Census Bureau. LTSB will submit data to the Census Bureau for the state as a whole. Section 13.96(1)(b) of the Wisconsin Statutes requires LTSB to “upon receipt of municipal boundary information at each reporting interval, reconcile and compile the information received to produce a statewide data base consisting of municipal boundary information for the entire state”. Section 13.96(1)(c) states that LTSB shall “Participate, on behalf of this state, in geographic boundary information programs when offered by the U.S. bureau of the census”. LTSB will publish Municipal Wards, Municipal Boundaries (cities, towns, villages), and County Supervisory Districts to the LTSB GIS Hub website. This data has been collected with the LTSB GeoData Collector. *with the exception of years ending in “01” where data collection will align closer to typical redistricting timelines of March and October 152026年2月采集的威斯康星州县督导选区数据集【属性定义】。因美国人口普查局（U.S. Census Bureau）数据交付延迟，本次采集工作从原定1月推迟至同年2月完成。本次数据采集依据威斯康星州州法第15条第4款第(br)1项开展。 根据州法第5.15条第4款第(br)1项规定，县书记员需于每年1月15日和7月15日前，将本辖区内的市政区划、市政选区及县督导选区的地理信息系统（Geographic Information System, GIS）格式数据提交至立法技术服务局（Legislative Technology Services Bureau, LTSB）。该条款原文规定："……县书记员需在每年1月15日及7月15日前，向立法技术服务局提交报告，确认本县内各市政区划、选区及督导选区的边界，并附本县地图，所提交文件需采用立法技术服务局认可的电子格式。每份报告需与报告提交前最近的1月1日或7月1日的边界信息保持同步*"。 根据州法第5.15条第4款第(b)项规定，市政书记员需在辖区边界变更发生后的5个工作日内通知县书记员。该条款原文规定："在本条项下的条例、决议或其修正案通过或颁布后的5个工作日内，市政书记员需将该条例、决议或修正案副本提交至该市政所属各县的县书记员，并附带(a)款规定的清单与地图。每份副本需标注市政名称及所属的一个或多个县名。" 1月采集批次的市政数据将由立法技术服务局通过边界兼并调查（Boundary Annexation Survey, BAS），用于更新美国人口普查局的TIGER（拓扑集成地理编码与参照系统）数据库中的市政边界信息。各县及市政无需再直接向美国人口普查局提交边界变更信息，改由立法技术服务局代表全州向普查局提交相关数据。 《威斯康星州法典》第13.96条第1款第(b)项要求立法技术服务局："在每个报告周期收到市政边界信息后，对所接收的信息进行核对与汇编，生成涵盖全州所有市政边界信息的州级数据库。" 《威斯康星州法典》第13.96条第1款第(c)项规定，立法技术服务局需"代表本州参与美国人口普查局推出的地理边界信息相关项目"。 立法技术服务局将把市政选区、市政边界（含市、镇、村）及县督导选区数据发布至其GIS枢纽网站（LTSB GIS Hub）。本次数据集通过立法技术服务局地理数据采集工具（LTSB GeoData Collector）完成采集。 *注：以"01"结尾的年份除外，此类年份的数据采集将调整至更符合典型重划选区时间表的3月及10月15日前后进行。
