Hamilton County Census Tracts (2020) - Open Data

This layer represents the boundaries of the 2020 Census Tracts in Hamilton County. Census tracts are: Small, relatively permanent statistical subdivisions of a county. Uniquely numbered in each county with a numeric code. About 4,000 inhabitants – Minimum Population – 1,200 – Maximum Population – 8,000. Designed to be relatively permanent over time. Any changes are documented so data can be compared from decade to decade. Census tracts are split or merged, depending on population change. Census tracts with more than 8,000 people are split into 2 or more tracts and are given an extension to their existing numeric code. Census tracts with less than 1,200 people are merged with a neighboring tract and are given a new numeric code. Small boundary corrections are sometimes allowed as well.

本图层展示了汉密尔顿县2020年人口普查区（Census Tracts）的边界。人口普查区是县内规模较小、具备相对稳定性的统计分区，在所属县内以唯一数字代码进行标识。其标准人口规模约为4000人，人口阈值下限为1200人，上限为8000人，设计初衷是长期保持相对稳定。所有区划调整均会被完整记录，以保障跨十年的统计数据具备可比对性。人口普查区将根据人口变化情况进行拆分或合并：当人口超过8000人时，会被拆分为2个及以上新区划，并在原有数字代码基础上添加扩展名以作区分；当人口低于1200人时，则会与相邻普查区合并，并被赋予全新的数字代码。此外，部分场景下也允许进行小幅的边界修正。
