How many twins die each year?

In conjoined twins or infant twins with health complications usually die within hours, days or weeks of one another. Most twins that live a full life do not necessarily die the same day, week, month or year and not always the same circumstances. It is a very small percentage that die within the same year due to extreme grief/depression. Some unusual co-incidences like twins that die the same day from unrelated road accidents or heart attacks have happened but very rare.

In general each twin even though they are born the same day, will have a different death dates.
