Abstract: Seismic vulnerability assessment is not only the basis for a long-term planning, but also provides support for emergency decision-making in earthquake emergency, therefore it is a focus in current research of vulnerability. First, this paper introduced the definition of seismic population vulnerability, and proposed its vulnerability factors and influence patterns. Second, after researching the macro and micro assessment models and methods of seismic population vulnerability, the macro assessment model of seismic population vulnerability was established by using five indicators, which are the total population, proportion of the young, proportion of the the old, population density and per capita GDP. The seismic population vulnerability at county level was assessed across China. The results showed that the differences of seismic population vulnerability were significant, the vulnerability in the eastern region was higher than that in the western, and the total population was the key factor. The assessment model designed in this paper had a significant effect on the amendment to the population vulnerability of the earthquake.
