As of 30 Aug 2023, ready-for-use Excel/CSV files of the uploaded datasets were not already available on data.gov.hk or Immigration Department platforms. Some datasets were created via collection of data through access-to-information requests. Thus they have been cleaned and made available on the CUHK Research Data Repository platform for wider access. For updated information, please refer to official sources or file an access to information request via the Code of Access to Information.
