Supplementary Information for: Forced labor risk is pervasive in the US land-based food supply

Summary of purpose: This dataset includes supply shares, risk scores, and data quality assessment. For more details, check the methods section (https://doi.org/10.1038/s43016-023-00794-x ). Nature: Supply data is quantitative data collected from Food Agriculture Organisation (FAO) adjusted to represent the share of suppliers from upstream levels of the supply chain. Risk and quality assessment (QA) are qualitative data transformed to quantitative by multiple methods. For more details, check the methods section (https://doi.org/10.1038/s43016-023-00794-x ). Scope of the data: US land-based food supply and forced labor risk associated, considering > 1% import share per item-country. File: 'SI_upstream_paths.csv' includes 16,642 observations (excluding totals which are embedded in the dataset). Meanwhile, files: 'SI_summary_tabular.csv' and 'SI_summary_tabular_AGG.csv' are aggregation with 1,312 and 212 observations respectively. Data timeframe from 2015 to 2019 and was collected between 2021-2022. A detailed description of each variable is in the file \"columns_description.\"

数据集用途概述：本数据集涵盖供应份额、风险评分及数据质量评估内容。如需了解更多细节，请参阅方法章节（https://doi.org/10.1038/s43016-023-00794-x）。
数据集属性：供应数据为从联合国粮食及农业组织（Food Agriculture Organisation, FAO）采集的定量数据，经调整后用于体现供应链上游环节供应商的占比情况。风险与质量评估（Quality Assessment, QA）则是通过多种方法将定性数据转换为定量数据所得。如需了解更多细节，请参阅方法章节（https://doi.org/10.1038/s43016-023-00794-x）。
数据覆盖范围：针对美国本土食品供应链及相关强迫劳动风险，统计维度为单品类-国家维度进口占比超过1%的样本。
