Alaskan Population Demographic Information from Decennial and American Community Survey Census Data, 1940-2016

These data comprise Census records relating to the Alaskan people's population demographics for the State of Alaskan Salmon and People (SASAP) Project. Decennial census data were originally extracted from IPUMS National Historic Geographic Information Systems website: https://data2.nhgis.org/main (Citation: Steven Manson, Jonathan Schroeder, David Van Riper, and Steven Ruggles. IPUMS National Historical Geographic Information System: Version 12.0 [Database]. Minneapolis: University of Minnesota. 2017. http://doi.org/10.18128/D050.V12.0). A number of relevant tables of basic demographics on age and race, household income and poverty levels, and labor force participation were extracted. These particular variables were selected as part of an effort to understand and potentially quantify various dimensions of well-being in Alaskan communities. The file "censusdata_master.csv" is a consolidation of all 21 other data files in the package. For detailed information on how the datasets vary over different years, view the file "readme.docx" available in this data package. The included .Rmd file is a script which combines the 21 files by year into a single file (censusdata_master.csv). It also cleans up place names (including typographical errors) and uses the USGS place names dataset and the SASAP regions dataset to assign latitude and longitude values and region values to each place in the dataset. Note that some places were not assigned a region or location because they do not fit well into the regional framework. Considerable heterogeneity exists between census surveys each year. While we have attempted to combine these datasets in a way that makes sense, there may be some discrepancies or unexpected values. The RMarkdown document SASAPWebsiteGraphicsCensus.Rmd is used to generate a variety of figures using these data, including the additional file Chignik_population.png. An additional set of 25 figures showing regional trends in population and income metrics are also included.本数据集包含与阿拉斯加三文鱼与人类（State of Alaskan Salmon and People, SASAP）项目相关的阿拉斯加人口普查记录。十年一次的人口普查数据最初从IPUMS全国历史地理信息系统（IPUMS National Historic Geographic Information Systems）网站提取：https://data2.nhgis.org/main（引用信息：Steven Manson、Jonathan Schroeder、David Van Riper及Steven Ruggles。IPUMS全国历史地理信息系统：版本12.0[数据库]。明尼阿波利斯：明尼苏达大学，2017年。http://doi.org/10.18128/D050.V12.0）。研究团队提取了多份涵盖基础人口统计维度的相关表格，涉及年龄、种族、家庭收入与贫困水平以及劳动力参与率等指标。选取上述变量旨在探究阿拉斯加各社区的福祉状况，并可对其多个维度进行量化分析。本数据包中的"censusdata_master.csv"文件为其余21个数据文件的整合版本。若需了解各数据集在不同年份的具体差异，请查阅本数据包内的"readme.docx"文件。本数据包附带的".Rmd"文件为一段处理脚本，可按年份将21个数据文件合并为单个文件"censusdata_master.csv"；该脚本还会清理地名数据（包括排版错误），并借助美国地质调查局（USGS）地名数据集与SASAP区域数据集，为数据集中的每个地点分配经纬度坐标与所属区域信息。请注意，部分地点因无法适配现有区域划分框架，未被分配所属区域或坐标信息。各年度的人口普查调查存在显著异质性。尽管研究团队已尽可能以合理方式整合这些数据集，但仍可能存在部分数据差异或异常值。RMarkdown文档"SASAPWebsiteGraphicsCensus.Rmd"可基于本数据集生成各类可视化图表，其中包含附带文件"Chignik_population.png"。本数据包还额外收录了25幅展示区域人口与收入指标变化趋势的图表。
