Prison Agriculture in the United States

The Prison Agriculture Lab at Colorado State University compiled a first-of-a-kind nationwide data set tracking prison agriculture in the United States. The data set identifies 1101 adult state-operated prisons, including 662 adult state-operated prisons with some type of crops and silviculture; horticulture and landscaping; animal agriculture; and/or food processing and production. These four types of agriculture are further broken down into subtypes, which are more detailed descriptions of an agricultural activity. The data set furthermore entails details on the specific drivers of agriculture, which are the goals or justifications for agriculture at each prison provided by prison authorities. The drivers are broadly classified into financial, idleness reduction, training, or reparative driver groups. Data covers all 50 states and was collected between 2019-2022 by speaking with prison authorities and by scraping official government and agency reports and websites. To enrich the geospatial aspects of this data set, the prison agriculture data provides a key to link with Homeland Infrastructure Foundation-Level prison boundaries data from 2020.

科罗拉多州立大学（Colorado State University）监狱农业实验室编制了全美首个追踪美国监狱农业活动的全国性数据集。该数据集收录1101所成人州立监狱，其中662所成人州立监狱开展了涵盖作物种植与营林、园艺与景观营造、畜牧养殖以及食品加工与生产的各类农业业务。上述四类农业活动还可进一步细分为子类型，以对各类农业作业进行更精细化的描述。此外，该数据集还包含各监狱开展农业活动的具体驱动因素细节，即监狱管理方提供的开展农业项目的目标与核心理由；这些驱动因素可大致划分为财务收益、减少囚犯闲置、技能培训以及修复性四大动因类别。本数据集覆盖美国全部50个州，采集工作于2019至2022年间完成，采集方式包括访谈监狱管理方、爬取官方政府及机构的报告与网站内容。为丰富该数据集的地理空间属性，本监狱农业数据集还提供了关联密钥，可用于与2020年发布的国土基础设施基础层级（Homeland Infrastructure Foundation-Level）监狱边界数据集进行关联匹配。
