In recent years, Statistics Canada has increased its use of paradata to improve the data collection process. In particular, it has implemented an approach to responsive design for some of its CATI household surveys. It has also started working on a theoretical framework for responsive design strategies. In the first part of the presentation, we will present results on the impact of responsive design using data from the Survey of Labour and Income Dynamics. We will also discuss plans to use paradata to improve collection in an RDD survey, the General Social Survey. In the second part of the presentation, we will give a general overview of some research on responsive design being conducted at Statistics Canada.
