Hi all,
I think this is mostly a Jeanne question, but thought I would post it to
the listserv to document protocols for handling this type of BaBase
correction . . .
Jeanne,
When you get a chance, could you please check my logic on the following
(I can show you the datasheets when you're back at Princeton). First,
I want to be sure that the changes I'm about to make are justified.
Second, I want to be sure I'm going about it the right way.
A note from Daphne indicates that Sister had an abortion in December
1988 and that this abortion was never entered into the BaBase Biograph
or Pregs tables. SIS's data in the Cycles table looks correct - the
problem is that it is not linked with a pregnancy. Looking back at the
sexskin datasheets, she conceived on 28 June 1988 (cid = 1688). The
abortion was 18 December 1988. Her resume cycle was cid = 1689.
If you agree that this abortion should be added reviewing the field
notes, here's how I'd go about correcting BaBase:
I would create a new row in Biograph for the abortion (same procedure as
on this as I follow during demography update with statdate = birthdate,
name field left blank, etc.). SIS had pregnancies both before and after
this abortion - this abortion will be inserted between SIS6 and SIS7.
Before SIS died in 1990, she had a total of 8 pregnancies (not including
this one). PID = SIS9 is the next pid in series. I would assign that
PID to this birth, but reorder the parity numbers such that the parity
for SIS6 is 6, SIS9 is 7, SIS7 is 8, and SIS8 is 9. I think this is
consistent with the protocols that Daphne explained last fall (never
change a PID but is ok to change the parity). These PID changes would
be made in both the Biograph and the Pregs tables. Finally, I would
also add a row to the Pregs table for PID = SIS9 with the conceive and
resume cycles entered in.
Thanks,
Catherine
