Singapore is an affluent and society, with a population of 74.3% Chinese, 13.4% Malay, 9% Indian, and 3% other races. 25% of the population is over 55 years old. Underneath the headlines of prosperity, there is a considerable disparity between the affluent and the poor in the country, but healthcare is available as is education. The details on the critical cases in Singapore will be telling if they become available.
That racial mix is of citizens and permanent residents. It doesn't include the so called "non-residents" who currently constitute about 30% of the people actually living there. Those ~1.7M people are of a quite different racial mix: a load (maybe 300K) of Indonesian and Filipino domestic servants for a start, plus a lot of ethnic Europeans, Indian labourers, etc.
