NLRB Annual Reports

The U.S. National Labor Relations Board’s Annual Reports were the agency’s yearly account of its casework. This is an archive of those tables, each reconstructed in machine-readable format alongside its full-page source scan, so every figure can be audited against the original.

For union-election data, better sources exist. See LaborData’s NLRB election datasets and Thomas Holmes’s NLRB election records (1977–1999).

A · marks a cell whose original content could not be normalized to a number — check the source image. Blank cells were empty in the source.

The whole dataset is available as machine-readable files (plus a CSV on each table’s page):

• Bulk data (Parquet) — every table cell in long/tidy form.
• Bulk data (CSV, gzip) — the same, as gzipped CSV.
