A. A PMR greater than 100 is considered elevated over the average compared to the general United State’s working population.

B. Due to confidentiality agreements with states, the number of deaths are reported in tables as ‘<5’ when a cell is based on less than 5 deaths, making the exact calculation of death in that category impossible.

^*indicates a significance (P-value) < 0.05
