Dear Statlisters,
I am trying to find : whether there is a "significant change in the mortality rate (death rate)" over the years from 1985-1989 among the new births in a particular geographical region. Please note that the exposure population is different for each year as the mortality rate is among the "new births" each year the region.

I wanted to confirm that a general poisson model such as below would be appropriate to find whether there was a significant change of mortality rates over the years (see the data below)


Model: Year is the explanatory variable

poisson death year, exposure(births) vce(robust) irr



Please consider the following data
