GC is a bit before my involvement in Traveller; when I tried to pursue a
copy with DGP, I was advised that it and Grand Survey had been consolidated
into a single work, and WBH was it.
Well, yes and no. Like Grand Survey which lost some stuff on volcanoes etc (shame, I liked that bit!), Grand Census did not make it in its entirety to World Builders' Handbook.
A quick (don't take this as exhaustive - and lots has been shifted round so I may have missed it somewhere) look through reveals:
front cover image to 1/4 page b/w
p.8 paragraph beginning "Linguistics..." removed
p.8 para beginning "Conclusive studies..." removed
p.8 para beg "In interstellar commerce..."
p.9 whole page on Linguistics skill and sample tasks removed
p.15 image of portable NAS sensor removed; NAS handset image revised
p.16 TL15 grav belt description reduced
p.20 some numbers regarding the TL15 g-carrier remove e.g. "Covered by 1cm thickness of light weight composite laminate, with amour factor of 10" & "120" ultraheavy grav modules
1/2 page illustration by Rob Caswell of Scout vessel in space with cut out of scout and alien and "stripes" of vehicles mentioned in book and logo of IISS
p.23 section on Creating the Cultural Profile removed (including note on Balkanized worlds)
p.24 three paras beg: "It's impractical..."

p.26 section on Law considerably reduced

p.28 section on Intelligent Native Life: Minor Races removed along with a partial list of Minor Races
p.29 section on The Roots of of Imperial Culture removed
p.30 section on The Terran Impact removed; section on Referee's Notes removed

p.37-39 three pages of rather useful and dense tech charts removed
p.40 section on Economics removed; section on Religion (notes for the tables) removed; along with religious tasks

[p.48] there's no index in WBH as there was in GC
Hope this helps.
