I am replicating a lifetime risk analysis that the CDC put out a few years ago regarding HIV infection among race and risk category. Currently the process uses a program called DEVCAN which was built for calculating lifetime cancer mortality. PROC LIFETEST is the only SAS procedure that is close to what I need. 

 

Its looks as though PROC LIFETEST, for survival analysis starts with a cohort and follows that group over time. Well, I am conducting this for an entire state's population and don't have each citizen as an observation. Is there a way to calculate with LIFETEST using this data format:

 

AGE         POPULATION      RACE          SEX             RISK              HIV_POS

1               8,000                    White           F                  None              5

2               9,000                    White           F                  None              0

3               10,000                  White           F                  None              0

.

.

85+           13,000                  White           F                  None              7

1               8,000                    Black           M                  None              8

 

...Instead of having each line be an observation like i have seen in each paper and example so far?

Do you have dates attached to those? Part of PROC LIFETEST does require a indication of the time of when events happen and it doesn't look like your data has those components.

The date component would be met using Age as the increasing time value.

Then look at the FREQ statement in LIFETEST.
