With the rapid development of urban construction, the scale of urban city transformation and infrastructure construction has gradually accelerated, and the process of construction waste reuse is imminent. The proportion of construction waste in domestic waste is basically constant, and the amount of household waste generated is inseparable from the number of people. In this paper, Hongsipu district is taken as an example, according to the trend of increasing population in the district year by year, the linear regression prediction method is used to predict the population of the district in the next few years, and then the future construction waste output in the district is predicted and analyzed. The results show that by 2027, it is predict that the population of Hongsipu district will be about 217,800, and the output of construction waste will be about 28 268.8 tons. The results can lay a foundation for subsequent resource utilization.
