While some of these are natural increases, the most significant changes have most likely occurred through migration. The percentage of increases in the Malaysian and “Other Bumiputera” populations far exceeds the increases in the Chinese and Indian populations, increases that most likely reflect a deliberate policy for ethnic redistribution and migration of labour from other parts of Malaysia to Penang. While the pattern of these changes has been consistent over the past forty years, the pace of change has accelerated in the past decade. A concern about out-migration is a main issue for the Government of Malaysia.
