Even though a ST report (Sept. 16) shed some light on the lack of socio-economic diversity among medical and dental undergraduates at the local universities – finding that two-thirds of them come from households earning more than $9,000 a month – a complete picture of socio-economic diversity among medicine and dentistry students remains elusive. We do not know how the income representation of students has changed over time. And in addition to household income, we do not know the socio-economic distribution of these students based on per-capita income, housing type, parental education and employment, as well as their past schools.
