According to ABC News, during the late 20th century and beginning of the 21st century, the greatest number of Americans died during January. That averages to over 735 people each day of the month.
ABC News reports that the increase in deaths is connected to flu season, when senior citizens and individuals who are already ill are at greater risk of dying. In comparison, the fewest number of deaths occurred during September.
The BBC indicates a worldwide pattern of deaths that peak between December and March. This phenomenon is referred to as "excess winter deaths." The BBC suggests that the deaths are not simply linked to extreme cold, but the reason for the extra fatalities is not clear.
