2023 California Delta Residents Survey

The Delta Residents Survey (DRS) was a household survey conducted in the Sacramento-San Joaquin Delta in Northern California in 2023 to better understand residents' attitudes on key social and environmental challenges in the region. The data were collected via a survey (available online through Qualtrics or as a print version), with survey invitations sent by mail to a random sample of 82,000 household addresses in the rural “Primary Zone” of the Delta (survey Zone 1), the suburban and urban “Secondary Zone” of the Delta (survey Zone 2) and Delta-adjacent “EJ Communities” in South Sacramento and South Stockton (survey Zone 3). Maps of the survey zones are available in project documentation and the Results Summary Report. The survey was available in English and Spanish. Over 2,300 responses were received, constituting a 2.9 percent response rate. The survey included 43 multiple choice and short response questions, broken up into five sections around key themes: Sense of place and way of lifeRegional priorities, concerns, and quality of lifeEnvironmental and climate change experiences, concerns, and policy preferencesCivic engagement and good governanceDemographicsThe research was conducted by a collaborative team of environmental social scientists across multiple research universities (UC San Diego, UC Davis, UC Berkeley, Oregon State University, and Sacramento State University) and was funded by the Delta Stewardship Council's Delta Science Program (a California State Agency). Significant community engagement and partnership efforts were carried out to improve the relevancy of survey questions and interpretation of data.Additional resources, including summary report of results and other research products using the data, are posted on our project website as they become available: https://ktomari.github.io/DeltaResidentsSurvey/.We also have a GitHub repository, where R scripts (and accompanying plain-text descriptions of the functions used that can be translated into other programming languages) are posted, which provide the easiest way for reading in the data and ensuring variable types are set correctly. We highly recommend using or referencing these scripts for the easiest and most accurate use of the data: https://github.com/ktomari/DeltaResidentsSurvey.

《德尔塔居民调查》（Delta Residents Survey，简称DRS）是一项于2023年在加利福尼亚州北部的萨克拉门托-圣华金三角洲地区进行的家庭调查，旨在更深入地理解该地区居民对关键社会和环境挑战的态度。该调查数据通过在线问卷（可通过Qualtrics在线访问或以印刷版形式提供）收集，并向随机抽取的82,000个家庭地址发送调查邀请，这些地址位于三角洲的乡村“主要区域”（调查区域1）、三角洲的郊区和城市“次级区域”（调查区域2）以及南萨克拉门托和南斯托克顿的三角洲相邻“环境正义社区”（调查区域3）。调查区域的地图可在项目文档和结果摘要报告中找到。调查提供英语和西班牙语两种语言版本。共收到2,300余份有效回复，占有效回复率的2.9%。调查包含43个多项选择题和简答题，分为围绕关键主题的五个部分：地域认同与生活方式、区域优先事项、关切与生活质量、环境与气候变化经历、关切和政策偏好、公民参与与良好治理、人口统计。该研究由多所研究大学（加州大学圣地亚哥分校、加州大学戴维斯分校、加州大学伯克利分校、俄勒冈州立大学和加州州立大学萨克拉门托分校）的环保社会科学家组成的协作团队进行，并由德尔塔治理委员会的德尔塔科学计划（加州州立机构）资助。为了提高调查问题的相关性和数据的解读，进行了显著的社区参与和合作伙伴关系努力。随着结果摘要报告和其他基于数据的研发成果的发布，我们将这些额外资源发布在项目网站上：https://ktomari.github.io/DeltaResidentsSurvey/。我们还在GitHub上设立了一个仓库，其中发布了R脚本（以及用于转换成其他编程语言的函数的纯文本描述），这些脚本为读取数据并确保变量类型正确设置提供了最简便的方法。我们强烈建议使用或参考这些脚本，以确保数据使用的最简便和最准确：https://github.com/ktomari/DeltaResidentsSurvey。
