Remigration
It is estimated that 30% of those Hong Kongers who moved away in the 1980s have returned to Hong Kong. Those that have moved back to Hong Kong have returned for various reasons - for economic reasons, or simply because they enjoy living in Hong Kong more than they do elsewhere. Specifically, many wealthy Hong Kongers who emigrated to Canada found that they could not adjust to the economic culture in Canada. The higher taxes and red tape and the language barrier made it difficult for them to do business. Comparatively speaking, doing business in Hong Kong was much easier.
"The concept of ‘return migration’ doesn’t quite capture the contingency and fuzziness of Hong Kong emigrant strategies. Returnees could go back to Australia at any stage, especially if they gained Australian citizenship. They could be planning to move back on retirement, or if there are unfavourable ‘changes’ in Hong Kong. suggests the term ‘return movement’, since ‘return migration’ assumes a permanency which may not be justified. Nevertheless, return movements should be distinguished from visits and various types of business and social ‘commuting’ of a very short-term nature."
