I think the question should be: how many ex-Malaysians and Singapore PRs are in this forum? These are the ones contributing to SG GDP in their prime years....
- ex-Malaysian (ie. given up M'sian citizenship) and now spore citizen
- M'sian citizen holding SPR status with intention to return to M'sia someday perhaps to retire
- M'sian citizen holding SPR status with no intention to return (eg. after marrying S'porean and starting a family in Sg)
