Deaths in America tend to surge in the winter and decline in the summer, as this chart by Jishai Evers of Dadaviz shows. Evers used data from the CDC to chart the how many Americans who died in each month between 1999 and 2013.
The smaller numbers inside the graphic represent the percentage of yearly deaths by month. As the graphic shows, December, January, February and March are often responsible for 9 or 10 percent of the year’s deaths. That percentage tends to fall to around 7 or 8 percent in the summer.
