Canadian Socioeconomic and Sociodemographic Prevalence at DA Level

The dataset provides the prevalence of various socioeconomic and sociodemographic variables at a dissemination area (DA) level granularity across Canada, in 2021. Each variable is expressed as a percentage (%) of the total relevant population within that DA, with the exception of median and average income variables, which remain in nominal CAD value. Key socioeconomic indicators include low income status based on the low-income measure, after tax (LIM-AT), low income based on the Low-income cut-offs, after tax (LICO-AT), spending 30% or more of income on shelter costs only, etcetera. Key sociodemographic indicators include visible minority, immigrant status, Indigenous status, unemployment, etcetera. The DAUID_21 column provides a unique identification code (aligning with Statistics Canada) for each individual DA across the country. In total the dataset captures 57,936 DAs and 53 indicators. The dataset can be paired with other DA-level exposure datasets (such as various air pollutants), in order to determine existing relationships between exposure risk and various socioeconomic and sociodemographic indicators. This is helpful in research pertaining to the disproportionate burden of environmental risk on minority and low-income populations, in addition to patterns of residential socioeconomic and sociodemographic characteristics across Canada. Due to the fine granularity, the dataset supports detailed urban analysis. All data was retrieved from Statistics Canada, using the 2021 Census of Population. Each individual dataset can be found within the Comprehensive Downloads section of the 2021 Census profile: https://www12.statcan.gc.ca/census-recensement/2021/dp-pd/prof/details/download-telecharger.cfm?Lang=E. Six individual datasets were merged together: Canada, provinces, territories, census divisions (CDs), census subdivisions (CSDs) and dissemination areas (DAs) for Atlantic only, Quebec only, Ontario only, Prairies only, British Columbia only, and Territories only. Data cleaning - to remove CD and CSD data - and dataset merging was all completed using R.本数据集提供了2021年加拿大各普查传播区域（Dissemination Area，DA）尺度下，各类社会经济与社会人口统计学指标的占比分布情况。各指标均以对应普查传播区域内相关总人口的百分比（%）形式呈现，仅中位数与平均收入变量除外，此类变量以加元名义值标注。核心社会经济指标包括基于税后低收入衡量标准（low-income measure, after tax, LIM-AT）的低收入群体占比、基于税后低收入 cutoff（Low-income cut-offs, after tax, LICO-AT）的低收入水平、仅住房支出占收入30%及以上的群体占比等。核心社会人口统计学指标包括可见少数群体身份占比、移民身份占比、原住民身份占比、失业率等。数据集内的DAUID_21字段为加拿大各地各普查传播区域提供了唯一识别编码，与加拿大统计局（Statistics Canada）的编码规则保持一致。本数据集共计涵盖57936个普查传播区域与53项指标。 该数据集可与其他普查传播区域尺度的暴露数据集（如各类空气污染物数据集）相结合，用于探究暴露风险与各类社会经济及社会人口统计学指标间的潜在关联。这一应用不仅有助于开展少数群体与低收入群体所承受的不成比例的环境风险负担相关研究，同时可用于分析加拿大全国范围内居住人口的社会经济与社会人口统计学特征分布模式。得益于精细的空间粒度，本数据集可支撑精细化的城市分析工作。 所有数据均来源于加拿大统计局，基于2021年加拿大人口普查获取。单份数据集可在2021年加拿大人口普查概况的“综合下载”板块中获取：https://www12.statcan.gc.ca/census-recensement/2021/dp-pd/prof/details/download-telecharger.cfm?Lang=E。本次共合并了6份单份数据集，分别为针对大西洋地区、魁北克省、安大略省、草原诸省、不列颠哥伦比亚省及各领地的全域、各省/地区、普查分区（census divisions, CDs）、普查子区（census subdivisions, CSDs）及普查传播区域（DAs）数据集。数据清洗（移除普查分区与普查子区数据）及数据集合并工作均通过R语言完成。
