For USA

from CIA factbook
Population growth rate: 0.9% (2001 est.)
Birth rate: 14.2 births/1,000 population (2001 est.)
Death rate: 8.7 deaths/1,000 population (2001 est.) More details on birth and death rates are avialable from CDC refer to cdc document for death rates
For all age groups the rate is 873 per 100,000
for the age group 25-34 the death rate is 108 per 100,000.
this is one in 1000. Then it doubles every 9 years or so.

what is the cause?
A lot depends on the age group. For 60+ it is the health.Mostly
heart problems or cancer takes them out.

For 25-34 it is accidents and some malignant neoplasms (cancer?).
Place of residence also plays a role. For californians the death rate
is 682 per 100,000 for all age groups. if you are in District Columbia
the chances are higher (1140 per 100,000).
If you are a male in 25 to 44 age then the leading cause of death is accidents. There is 0.05% (50 per 100,000) that you would die this year due to an accident. Again if you are a male in the age group of 25 to 44 then there is 0.2% (200 per 100,000) that you would die this year (of any cause).

It is intersting to see how the life expectancy changes with age.
If you are 65 then your expected remaining life is 18 years.
So if you were to retire at 65, you should plan for that much.
That is a life of 83 years.
if you are alive at 60 then your remaining life is about 21.6.
So may be you live up to 82 years. You see the longer you live,
the longer you are likely to live. Obvious?
For better or worse, you may live longer or shorter with equal
probability.
