Abstract

OBJECTIVE: To use available suicide-rate data from 20 countries to see patterns and relations more clearly.
METHOD: We obtained raw suicide rates from the Organization for Economic Cooperation and Development (OECD) database from 1960 through 1997 and calculated averages and standard deviations.
RESULTS: There is a positive linear relation between the variation in suicide rate and geographic latitude.
CONCLUSIONS: The variation in light-dark cycles is superimposed upon human mood.
