From a population of 747 registered suicides, a sample of 106 note-writers & 106 non-note writers was examined. Using the demographic (descriptive) scheme of Ho, Yip, Chiu, & Halliday (1998), the results indicated note writers do not differ greatly from other suicides. The less educated understandably wrote fewer notes. The most intriguing finding was that suicide in Mexico was associated with a array of factors, notably interpersonal problems. (22 refs.)
