Aiming at the problem of “No one at home” in China’s census work, a solution based on big data of power grid to the census work is proposed. With the support of big data technology, models for identifying vacant houses and predicting households at home are established by analyzing the electricity consumption and trends of each house. Besides, a data analysis platform based on power grid big data was developed to provide census staff with data support, such as the vacancy status of residential houses and the probability of residents at home. It has been verified that the research program is effective, which can reduce the workload and improve the efficiency of the census work.
