Population-related information is vitally important in all modern societies. Population data of various sources are continually being collected and are increasingly available along with sophisticated analytical tools. Population studies centers are thus now commonplace in all of the leading universities around the world. The HKU Research Hub of Population Studies has quickly established itself as an important research center with international recognition. Many of the basic features of an ideal research center have already been put into place. At this stage, the Research Hub primarily needs to maintain its continuity by fostering a few new appropriate enhancements. The educational and scholarly mission of a vibrant Research Hub promote not only the productivity of HKU academic staff, but also enhance reputation of HKU as well as benefit the wider Hong Kong and GBA communities.HKU cannot remain competitive as a world-class university if a superlative population studies center is not maintained.
