Actually that is NOT normal. Deleted account space if returned to
the pool of free space and "defragmentation" is "online and automatic."

1 Gig of NTDS.dit is equivalent to about 250,000 users. (Or other
objects but they usually don't amount to the largest portions).

The online degrag does not however "shrink" a database -- but that
is not really an issues unless you add tens of thousands (or more)
users and then delete them and want the space back.

The misnamed "offline defragmentation" procedure will shrink
the database, but it's needed for the normal "add a 100, delete
a 100 users" pattern in a large production system.

Not really, since you must boot in Directory Services Restore mode
which doesn't seem to be scriptable.

How many Users and/or Computers do you have?

1 Gig is quite large for a database in most companies.
