Usage Notes
Because "死亡" is formal, in everyday conversation people often use "亡くなる" (なくなる) as a polite way to say someone has died. Avoid using "死亡" in casual talk about death to sound natural. Also, do not confuse "死亡" with "死ぬ" which is the plain verb "to die." "死亡" is a noun and often paired with "する" to form a verb phrase.
