Annual US state union-membership density intelligence from the BLS Current Population Survey 'Union Members' releases (agent-curated Table-5 transcription, 2021-2025): union density and contract-representation rates for the 50 states and the District of Columbia, with year-over-year moves, 5-year organizing-trend slopes, per-year density ranks, a documented 0-100 organization-pressure score, and high/low density plus rising/falling flags. Caveats: CPS union data rest on one quarter of the CPS sample (broad characterizations only); 2025 is an 11-month average (October 2025 not collected — federal shutdown) and is not strictly comparable. BLS material is public domain (commercial reuse allowed); source: U.S. Bureau of Labor Statistics.

| Colonne | Type | Description |
|---|---|---|
| year | integer | Reference year (BLS annual average). Panel covers 2021-2025. (unit: year) |
| country_code | string | ISO alpha-3 country code (USA for every row). (unit: ISO 3166-1 alpha-3) |
| state_code | string | Stable geography code: USPS postal abbreviation, lowercase (ca, tx, ny, ..., dc). Primary join key with year. |
| state_name | string | State / District name as published by BLS. |
| employed_k | float | Employed wage and salary workers (BLS Table 5), thousands. (unit: thousands of workers) |
| union_members_k | float | Wage and salary workers who are union members (BLS Table 5), thousands. (unit: thousands of workers) |
| union_density_pct | float | Union members as a percent of employed wage and salary workers (BLS Table 5), kept verbatim as published. (unit: percent) |
| represented_k | float | Workers represented by a union (members plus workers covered by a contract who report no affiliation; BLS Table 5), thousands. (unit: thousands of workers) |
| represented_pct | float | Workers represented by a union as a percent of employed (BLS Table 5), kept verbatim. (unit: percent) |
| contract_premium_pp | float | represented_pct minus union_density_pct: the share of workers covered by a union contract without being members. (unit: percentage points) |
| density_yoy_pp | float | Year-over-year change in union density, percentage points. Null for 2021 (no base year). (unit: percentage points) |
| density_5yr_trend_pp_per_yr | float | OLS slope of union_density_pct on year over the available window (pp per year): the structural organizing drift, robust to single-year CPS noise. (unit: pp per year) |
| density_rank | integer | Per-year rank of union_density_pct across the 51 geos (1 = most unionized). (unit: rank) |
| organization_pressure_score | float | Documented 0-100 composite: 100 * (0.65 * min-max(union_density_pct) + 0.35 * min-max(clipped density_yoy_pp, +/-2 pp)), min-maxed within each year across the 51 geos. Higher = the most unionized / fastest-unionizing labor market that year. (unit: 0-100 score) |
| high_density_flag | integer | 1 when union_density_pct >= 15%. (unit: binary) |
| low_density_flag | integer | 1 when union_density_pct <= 5%. (unit: binary) |
| density_rising_flag | integer | 1 when density_yoy_pp >= +0.5 pp. (unit: binary) |
| density_falling_flag | integer | 1 when density_yoy_pp <= -0.5 pp. (unit: binary) |
| estimate_note | string | Collection caveat carried verbatim; set on 2025 rows (October 2025 CPS not collected — federal shutdown; 11-month average, interpret with caution), null otherwise. |
| source_url | string | BLS release URL the row was transcribed from (Table 5). (unit: URL) |
| row_hash | string | Deterministic 16-hex row hash of state_code + year (idempotency). |
