Many thanks Bruno for the prompt response.
I am using the Ghana dataset. For The marital fertility rate using, . tfr2, entry(v509), if v501==1 | v501==2 was higher than the tfr2,entry(v509) . eg using the 2008 dataset GHIR5HFL.DTA", gives 6.195775 as compared to 5.850916. Thanks so much.

However, trying the non-marital fertility rate with "GHIR5HFL.DTA", gives this error message
Maximum number of iterations exceeded.
r(498);
Besides, I observed, the period covered to have been 10 years earlier, that is 12/1995 to 11/1998 is instead of 2005-2008
I used:

gene dates=cond(v509!=., v509, v008)
gene entry=v008-36
tfr2, entry(entry) dates(dates)

This worked for the 2003 Ghana dataset but again, the period was 10 years ahead. 1990-1993, instead of 2000-2003
The output obtained was:

tfr2, entry(entry) dates(dates)
weight variable is v005
Preparing table of events and exposure for 3 year(s) preceding the survey
Period covered: 5/1990 to 4/1993
Central date is 1991.8359
Number of cases (women): 1851
Number of person-years (weighted): 3925.2241
Number of events (weighted): 80.825775
