Population Studies


The research theme of population studies covers a wide range issues relating to population and wellbeing. Our work involves the major components in population dynamic modelling, namely, fertility, mortality, marriage and divorce, poverty, and migration. International comparison has been conducted examining fertility and international migration. The research theme is supported by a strategic public policy research (SPPR) on integrated population policy, a Chief Executive Community project on poverty, numerous peer review UGC and international grants.

Our expertise covers a wide range of population modelling tools, including spatial analysis to examine poverty and service provision in Hong Kong and multilevel modeling to examine wellbeing of the population in individual, household and community levels. We are developing assessment tools in social return on investment (SROI) and program evaluation for many social and welfare programs. The wellbeing of migrants and their left-behind families is also another area of interest.

There are active and intensive international research collaborations with colleagues at Melbourne University, National University of Singapore, Renmin University, Fudan University, and Columbia University. Interdisciplinary research teams have been established with colleagues in faculties of humanities, medicine, business and science. Innovative methods have been developed in understanding the population dynamics with real impact to the social and public policies in Hong Kong and other global regions of the world. We have also provided consultancy service to Hong Kong SAR Government, OECD, UNICEF, Terres D'Hommes and many other local organizations on population issues.

The members are also serving in a number of Government committees, for example, Commission on Poverty, Care Fund, Central Policy Unit and Strategic Population Policy Committee.
