a Degradation Curve for gender groups(The curve illustrates the network’s ability to maintain functionality given sequential disruptions. A shallower gradient on the degradation curve and a larger area under the curve indicate better robustness performance for this group. The curve was generated by progressively removing nodes from the network based on three predetermined lists, while functionality was continuously computed after each step by examining paths for OD flows of each social group. The integral method is then applied to calculate the area under the curve, indicating the system’s robustness for each social group. The simulation for random disruption is repeated five hundred times to generate an averaged degradation curve, ensuring the reproducibility of results. As a result, the degradation curve for this scenario displays a smoother trend compared to the other scenarios.) b Degradation Curve for age groups (In the lower right corner, we demonstrate the significant negative correlation between the ATD and robustness in both the Random disruption and ND attack scenarios). c Degradation Curve for income groups.
