Challenges and Emerging Issues in Official Statistics and Survey Methodology

在过去十年中，官方统计和调查方法领域发生了巨大的变化。像加拿大统计局这样的官方统计机构已经超越了传统的调查优先的方法，采用了综合各种现有来源的数据的新方法。虽然一些老问题仍然存在，但这些演变给官方统计和调查方法研究的所有主要阶段带来了新的挑战，包括数据收集、生产、获取和统计分析。拟议的研究解决了新挑战和新问题的三个关键组成部分：(1)创建公共使用数据文件，在不损害隐私和保密性的情况下促进有效的科学调查；（二）开发分析超大数据文件和（或）实时数据文件的统计方法；(3)处理有偏差和非概率调查样本和非常规来源数据的方法的进步。该建议部分基于申请人最近成功完成的相关主题的研究项目，并回应官方统计机构、数据使用者、决策者和调查从业者的呼吁，以解决新数据时代出现的重要问题。

The fields of official statistics and survey methodology have seen drastic evolutions during the past decade. Official statistical agencies such as Statistics Canada have been moving beyond the traditional survey-first approach to new methods integrating data from a variety of existing sources. While some of the old issues remain, the evolutions bring new challenges to all major phases in official statistics and survey methodology research, including data collection, production, access, and statistical analysis. The proposed research addresses three critical components of new challenges and emerging issues: (1) the creation of public-use data files to facilitate valid scientific investigations without compromising privacy and confidentiality; (2) the development of statistical methods for analyzing excessively large and/or real-time data files; and (3) the advancement of methodologies for dealing with biased and non-probability survey samples and data from unconventional sources. The proposal is built based partially on the applicant's recent successfully completed research projects on related topics and answers the call from official statistical agencies, data users, decision makers and survey practitioners to tackle important emerging problems in the new data era.
