Where can I pull this from? I am guessing it's just number of dead tuples /
row count, but Im not exactly sure. Would like to show these factors per
relation in an overall view I have.
Thanks.

The row count of the table is taken from pg_class.reltuples, and the number
of dead tuples is taken from the "pg_stat_get_dead_tuples" function.
Note that the autovacuum parameters can be overridden by storage parameters
on the table.
Yours,
