The first individual of the first line of the year 1981 is the same

How is this consistent with an unbalanced panel as the subject line
states? Are there blank lines for the missing observations?

I don't know if I understood the data structure correctly, but if I
do, this should produce a tsset that you can then use with xtreg or
other panel data tools. There's probably a better way to do this than
what I'm suggesting.
gen individual_ID = 1
replace individual_ID = individual_ID[_n-1] + 1 if (_n>1) & (year[_n]
== year[_n-1])
quietly sum individual_ID
replace individual_ID=individual_ID + (id - 1)*r(max)
tsset individual_ID year
Peace,
