题 目：Digital Twins and Demography 数字孪生与人口学

摘要：A digital twin is a virtual model designed to accurately reflect the form and functioning of a physical object. Attempts to extend the concept to replicate cities are limited by the use of aggregated data to represent the elemental human agents that live, work and take leisure in them. In this presentation we: (a) develop data driven approaches to model the gender, age and ethnic characteristics of individuals using unique consumer data sources; (b) reconcile these individual level predictions with social surveys and remotely-sensed data; and (c) assess the implications for geodemographic forecasting of social and economic change.

We also propose micro-scale demographic models to simulate the characteristics of individuals that are known to be missing from our representations. The resulting digital twins will be used to investigate issues such as residential segregation, residential mobility and the kaleidoscope of social change that characterises urban social areas.
