Anonymized mobile phone CDR allows the user to capture dynamics of mass population movement where individual trajectories are still traceable. While, outcomes of research analyzing CDR merely show distribution of people or crowds, which are aggregation of mass trajectories without any attributes. To further investigate hidden properties of human mobility in CDR, it is critical to analyze such data in combination with secondary datasets. This paper develops real-time census of greater Dhaka from CDR. It represents population composition of greater Dhaka and is labeled with demographic attributes such as sex, age groups, and occupational types.
