Summary

Seasonal or monthly fluctuations in suicides and homicides were analysed using US mortality data for the years 1969–78, using periodic regression analysis. The results were generally consistent (year-to-year) over the 10-year period. The pattern for suicide was distinctly seasonal: it was above average all spring and below average all winter. For homicides, the pattern was more monthly, with July–September and December being above average times and January–June being below average.
