Note regarding the variables in the 2004 SCF for planned retirement ages of the head and spouse.

Thinking now of the future, in what year or at what age

(do you/does your [husband/wife/partner]) expect to stop working full-time?

X7728(#1) *Code age
X7727(#2) -2. *NEVER STOP
0. Inap. (not doing any work for pay: X4105=5/X4705=5;/
no spouse; not currently working full-time: X4511^=1/
X5111^=1)

When we use X7728 (planned retirement age for head/husband/male partner/older partner in same sex couple) no problem.

However, when we try to use X7727 (planned retirement age for wife/female partner/younger partner in same sex couple) we get the message "Variable X7727 not found"

Response from SCF staff:
Thanks for finding that!! It will be fixed the next time we update the dataset.

Luckily it can be easily calculated:
if X5124=-2 then X7727=-2; else X7727=X19+MAX(0,X5124);
