Adult foxes with low (0--20%) and high (80--100%) row-crop percentages, and higher capture weights experienced higher survival. Juveniles from larger litters, low capture body fat, and fewer dispersal days had higher survival. Adult survival (0.35) was higher than juvenile survival (0.24). Yearly urban survival varied due to cyclic outbreaks of sarcoptic mange, resulting in survival ranging from 0.10 (mange prevalent) to 0.83 (no mange) indifferent years.
