"... it is important to understand the average age / life expectancy of the population"
 
If the study was done properly, the number of 14 "expected" cases would represent the "age/gender/etc. adjusted" expectation which should acount for this potential bias.

Among what I found this far is 27 cancer cases instead of 14 expected for the years
1994-2004. I assume that this relates to incidence - not deaths.

Now, in order to interpret such data it is important to understand the average age / life expectancy of the population: If they become older (because they have jobs) that could explain some of the effect - cancer incidence increases sharply with age (especially after age 55-60).

Comments?

My personal reflections only,
