To investigate the extent to which those who responded to the GOS are representative of the in-scope population, respondent characteristics are presented alongside population parameters in Table 21 and Table 22 below. Some groups in the achieved sample are represented broadly in-line with their sample proportion, with mode of attendance and disability status particularly well-matched for both undergraduate and postgraduate coursework graduates. The largest potential source of non-response bias is in relation to home country, main language spoken at home, and age for international graduates. Chinese graduates are under-represented in the responding sample by 15.2 percentage points. There was good representation across all other home countries that make up the top ten home countries for international graduates. Graduates who speak a language other than English at home were also less likely to respond, with those who speak a language other than English under-represented in the responding sample by 4.2 percentage points, relative to population parameters. Graduates aged thirty years or below were also under-represented by 5.3 percentage points. 2021 GOS International Report 31
