As the national adult suicide rate increases, news stories about suicides during the holidays grow in number
A common misperception about the end of year holidays is that more people commit suicide during this period than at other times in the year. Since 2000, the Annenberg Public Policy Center has been tracking press reporting about this widespread belief. In the millennium year of 1999, APPC identified over 60 stories that ran during
