Sorry, when I looked, the 96k was clearly labeled. You should be able to see the relevant numbers on your Employment page. Of course the incoming Corporation is built and it no longer shows the 96k as needed.
From January up to June, it shows your Schools increasing each month. This says to me you did indeed have things being built. Maybe on auto-build? A few incoming Schools, High Schools and so on could definitely make up the little difference from your latest example.
