This site says that malayalees are second largest indian group
in Singapore.
Singapore, one of the few remaining city-states is the
smallest
country in South East Asia with a land area of 272 sqm (704
km2 ).
It is the second most densely populated independent
country
after Monaco. As of September 2007, the population of
Singapore
was 4.68 million. 3.7 million were citizens and permanent
residents.
Chinese formed 75.2%, Malays 13.6%, Indians 8.8% and
Eurasians
and others 2.4%.
Malayalam is the mother tongue of Malayalees, who
form the second
largest ethnic group within the Indian community
in Singapore;
constituting 20% (25, 000) of the Indian population. Malayalam
belongs to a family of Dravidian languages and originates from
Kerala,
the south-western coast of the Indian sub-continent. Malayalam is
not a
dialect; it is a language with a very rich and flourishing
literature...

What the site says, is quite true.
The sad thing about the Malayalees in both Singapore and
Malaysia today, is that they have given up their native Malayalam
language and almost all only can speak Tamil language today
already.
