I would try the following:
ALTER TABLE hewitt_1_0_factors_precalc_new SET STATISTICS 1000;
ALTER TABLE census_user SET STATISTICS 500;
ALTER TABLE census_output SET STATISTICS 500;
and analyzed them after. I hope I guessed ‘census_output’ name correctly.

And could you kindly share the plan after:
SET enable_nestloop TO off;
