Is this comparing firearm related accidents/homicides or all types of accidents/homicides?
All types of accidents and homicides; I used the information from a document I now can't find! However, check Table B on page 9 in this document:
http://www.cdc.gov/nchs/data/nvsr/nvsr59/nvsr59_04.pdf
Accidents (unintentional injuries): 117,176
Assault (homicide): 16,591
The ratio in that document is actually 7 to 1.
This document has breakdowns by broad age groups:
http://www.cdc.gov/nchs/data/databriefs/db64.pdf
As expected of their relative health and low life experience, ages 1 to 24 die mostly due to accidents (38%), homicide (14%), suicide (12%), cancer (7%) and heart disease (3%). This group might improve their situation by arming themselves (but might actually also accidentally shoot themselves or someone else.)
Ages 25 to 44, homicide (6%) is less "probable" than even suicide (10%) with accidents still the leading cause (25%) of death (health issues are starting to dominate.)
Above age 44, health problems are what kills people, with accidents, homicide, and suicide dropping to very small relative percentages.
