Webinar Abstract
The HLG-MOS ASCENT Project (Advanced Survey Cost-Effectiveness with Nonresponse Treatment) is an international initiative led by Statistics Canada in collaboration with 13 National Statistical Offices (NSOs). It responds to the growing challenge of declining response rates and increasing risks of nonresponse bias in social surveys, within a context of constrained resources and rising demand for timely, disaggregated statistics. This presentation introduces the ASCENT guide, a set of practical, use-case-oriented principles and tools designed to support NSOs in reducing nonresponse bias within existing survey systems. The guide focuses on short- to medium-term, implementable strategies grounded in the Total Survey Error framework and aligned with international statistical standards. It brings together multiple complementary areas of work: multi-mode collection strategies and weighting adjustments, subsampling of nonrespondents with targeted follow-up, and enhanced calibration and responsive design approaches. These methods aim to improve accuracy while maintaining operational feasibility and cost-effectiveness. The objective is to provide NSOs with practical guidance to improve the quality and reliability of social survey outputs, strengthen comparability across countries, and support evidence-based decision-making in an increasingly complex data environment.
