```There is a variable which isolates those that were born in 1988 and those
with missing values (coded as 88).

85 |        487        3.08       41.93

88 |        650        4.12       53.07
89 |        525        3.32       56.39

history data

I have a substantive query in return, fired
by idle curiosity.

In your data for -year- (below) there is a big peak in 1988.

On another variable, it seems that "88"
was used to code missing, as you excluded
it from tabulation. Is it possible
that the real 88s for -year- (i.e. born in 1988)
have got mixed up with missings (coded 88) ?
