Regional commercial salmon permit earnings by residency status, Alaska, 1975-2016

This dataset synthesizes several existing datasets of permit earnings to estimate permit earnings by residency status in Alaskan commercial salmon fisheries by the region in which fish are harvested. The Alaska Department of Fish and Game Basic Information Tables (Alaska Department of Fish and Game, Commercial Fisheries Entry Commission. 2018. Commercial Fisheries Entry Commission Basic Information Table, 1975-2016. Knowledge Network for Biocomplexity. doi:10.5063/F1HX19Z2) were used in conjunction with the Commercial Fisheries Entry Commission public permit database (Commercial Fisheries Entry Commision CFEC. 2016. Commercial Fisheries Entry Commision Public Permit Database from 1975-2016. Knowledge Network for Biocomplexity. doi:10.5063/F12R3PZM.) and available fish ticket data (Alaska Department of Fish and Game, Commercial Fisheries Entry Commission. 2018. Commercial Fisheries Entry Commission Permit Earnings, 1975-2016. Knowledge Network for Biocomplexity. doi:10.5063/F1D50K8H) to create the best possible estimate of regional earnings with residency information. These three datasets were used in conjunction since a portion of the fish ticket data is confidential, and public data using higher levels of aggregation with the regions of interest for this study was not available. The data here are presented as earnings by residency. Residency is categorized as nonresident (permit owner resides outside of Alaska), resident local rural (permit owner resides in the same district as the fishery, in a rural community), resident local urban (permit owner resides in the same district as the fishery, in an urban community), resident nonlocal rural (permit owner resides in a different district than the fishery, in a rural community), and resident nonlocal urban (permit owner resides in a different district than the fishery, in an urban community). The urban/rural distinction is made on a community basis by the Alaska Department of Fish and Game. All earnings values are presented in adjusted 2017 dollars using the Bureau of Labor Statistics Consumer Price Index data for Anchorage. Included in this dataset is a file with annual total earnings by region and residency (regional_earnings_residency.csv), an R markdown document used to make the file (permitearnings.Rmd), several reference tables used in data formatting, and figures showing results by region.

本数据集整合多套现有许可证收入数据集，旨在基于鱼类捕捞所在区域，估算阿拉斯加商业鲑鱼渔业中按居留身份划分的许可证收入。

本研究依托阿拉斯加鱼类与野生动物部（Alaska Department of Fish and Game）、商业渔业准入委员会（Commercial Fisheries Entry Commission）2018年发布的《1975-2016年商业渔业准入委员会基础信息表》，该数据收录于生物复杂性知识网络（Knowledge Network for Biocomplexity），DOI:10.5063/F1HX19Z2；同时结合商业渔业准入委员会2016年发布的《1975-2016年商业渔业准入委员会公共许可证数据库》，收录于生物复杂性知识网络，DOI:10.5063/F12R3PZM；以及公开可获取的渔获票据数据——阿拉斯加鱼类与野生动物部、商业渔业准入委员会2018年发布的《1975-2016年商业渔业准入委员会许可证收入数据》，收录于生物复杂性知识网络，DOI:10.5063/F1D50K8H，以生成最贴合实际的区域维度居留身份收入估算结果。

由于部分渔获票据数据属于机密内容，且本研究所需的区域聚合级公共数据无法获取，因此整合上述三套数据集完成分析。

本数据集按居留身份对收入进行分类，具体类别如下：非居民（许可证持有人常住地不在阿拉斯加州）、本地农村居民（许可证持有人与渔场同属一个渔业辖区，且常住地为农村社区）、本地城市居民（许可证持有人与渔场同属一个渔业辖区，且常住地为城市社区）、非本地农村居民（许可证持有人与渔场分属不同渔业辖区，且常住地为农村社区）、非本地城市居民（许可证持有人与渔场分属不同渔业辖区，且常住地为城市社区）。其中城乡社区的划分标准由阿拉斯加鱼类与野生动物部制定。

所有收入值均以2017年不变价呈现，换算依据为美国劳工统计局安克雷奇分支的消费者物价指数（CPI）数据。

本数据集包含以下文件：按区域和居留身份划分的年度总收入表（regional_earnings_residency.csv）、用于生成该表格的R Markdown文档（permitearnings.Rmd）、若干用于数据格式化的参考表格，以及按区域展示分析结果的可视化图表。
