Geographical Infrastructure for the City of Boston v. 2023

The Boston Area Research Initiative’s Geographical Infrastructure for Boston is a database that organizes and links the places and regions of Boston, MA across 17 levels—including land parcels, streets, census geographies, and other administrative regions. The levels are organized in a hierarchy, with the items in each level nested in the higher-level regions that contain it (e.g., land parcels in census geographies). This is coordinated via variables that act as unique identifiers at each level. As a composite, the database is intended to facilitate aggregate calculations across levels of the hierarchy and analyses of data from different sources that reference the same geographical units. In particular, the database makes it possible to connect data sets generated by the City of Boston with census geographies and data. Note: Only data sets that were updated in 2023 are posted here. See earlier versions of the Geographical Infrastructure for the other data sets (e.g., census, administrative geographies)

波士顿地区研究计划（Boston Area Research Initiative）的波士顿地理基础设施（Geographical Infrastructure for Boston）是一个数据库，它对马萨诸塞州波士顿市的地点和区域进行组织并建立关联，涵盖17个层级——包括地块、街道、人口普查地理区域及其他行政区域。这些层级按层级结构组织，每个层级中的项目嵌套在包含它的更高层级区域中（例如，人口普查地理区域内的地块）。这通过在每个层级充当唯一标识符的变量来协调。作为一个复合数据库，其目的是促进跨层级结构的聚合计算，以及对引用相同地理单元的不同来源数据的分析。特别是，该数据库能够将波士顿市生成的数据集与人口普查地理区域及数据连接起来。注：此处仅发布2023年更新的数据集。其他数据集（如人口普查、行政地理区域数据集）请参见地理基础设施的早期版本。
