Singapore is 74% Chinese, 13% Malay, 9% Indian (I think Flocc is in this group, a Karelian Christian IIRC) descent with 3% "other". Singapore has been described as the third China, it's the only country where Chinese constitute a majority of the population outside the Chinas themselves.
The Chinese population isn't homogenous- there's a huge split between the middle and upper middle, English speaking, largely Christian classes and the Mandarin or Dialect speaking, largely Buddhist/Taoist lower middle and working classes.
There's also a massive split between the Singaporean Chinese and the immigrant population of PRC citizens.
I'm from Kerala, not Karelia, btw

The Indian population is similarly split, again between a middle and upper middle class largely of Tamils, Punjabis, Sindhis and Malayalees and a large working class Tamil population. Again, there's a growing Indian national population- there's been a massive upswing in Indian related events and so forth and the Singaporean Indian middle and upper classes seem to at the moment be actually reconnecting with upper middle class Indian society where they had previously been sort of but not quite socially connected to the Singaporean Chinese upper middle classes. This has actually been happening all over the world as the Indian diaspora reconnects with a growing India- I think my wife and I sort of exemplify this; she being an Indian national and I being third generation Singapore Indian. It should be noted that the Tamil working classes tend to have very few connections back in India and are pretty much left out of this process. There's a population of Indian and Bangladeshi labourers but they're here on contract basis and are largely ignored by the Singaporean Indians.
The Malay population, on the other hand, tends to have a lot of socioeconomic problems- drug use, teen pregnancy, unemployment and so forth. They actually exemplify a lot of the problems with the healthcare system since certain diseases (like diabetes) operate with genetic predispositions and Malays happen to be one of the racial groups most susceptible to this. Thus you have a lot of resentment towards a system that doesn't necessarily provide for sufferers of long term chronic illnesses which disproportionately hit the Malay population- whereas the Indians, for example tend to be prone to heart disease which means we have a tendency to drop dead with a bang- not really much in the way of medical bills- and the Chinese eat healthy and live forever
