ABSTRACT

The 2011 Census Origin-Destination Statistics collated and released by the Office for National Statistics are much more extensive than those generated from previous censuses, covering student mobility and second home ownership as well as migration and journey to work flows. This chapter explains some of the basic concepts underpinning these data, outlines the questions on the census questionnaire from which the counts of different flows are derived and indicates what data are available under different access conditions at different levels of geography. The chapter also provides some guidance to users who want to use the online interface WICID to build queries to extract and download the flow data they require for subsequent analysis.
