Summary (NLx corpus)
Aggregate evidence from the NLx corpus. This top-level page is a hub for profilers and corpus-level checks using aggregate data from the national NLx corpus; USAJOBS-only federal evidence is kept in the USAJOBS section. The NLx corpus represents approximately 162 million source postings before monthly expansion; dashboard rates use monthly active posting-month rows.
