Each observation identifies a city and census year, an occupation class, and a demographic group, and reports group shares in the municipal population and in the local government workforce; the file also includes binary flags recording whether a state-level mandate applied and whether a municipal civil service commission was in place, plus a numeric distance-from-cutoff measure used for threshold-based comparisons. The underlying sources include full-count census enumerations (industry/occupation and birthplace fields), historical surveys of municipal civil service adoption, and compiled state session-law information assembled to create a harmonized longitudinal dataset on municipal staff composition.","file_sha256":"d5035ee26421d944dd396fa22c1f412e72a32f59388ef130ad486a3c851a813b","frame_sha256":null,"role":"agent","transforms":[]},"ref_iv":{"description_shown":"","file_sha256":"d5035ee26421d944dd396fa22c1f412e72a32f59388ef130ad486a3c851a813b","frame_sha256":null,"role":"reference","transforms":[{"args":{"query":"occ == 'blue_collar' and name == 'white_x_native_born'"},"op":"filter"},{"args":{"columns":["govt","treat_actual","treat_assign","pop","YEAR","city"]},"op":"select"},{"args":{"columns":["govt","treat_actual","treat_assign","pop","YEAR","city"]},"op":"dropna"},{"args":{"column":"YEAR","drop_first":true,"prefix":"YEAR"},"op":"dummies"},{"args":{"column":"city","drop_first":true,"prefix":"city"},"op":"dummies"}]}},"epoch":1,"event":"sample_init","question":"What is the causal effect of municipal civil service reform adoption on the share of blue-collar municipal government jobs held by native-born white workers, estimated for municipalities whose adoption was externally induced (local compliers)?","question_sha256":"00aff9a6acb5300043926f15ca4a01f3e1c8f4d25b4d46aa52b547a8f91e834f","run_id":"20261015T170957Z-suite-crb_papers-baseline-dae0c1","seq":0,"skills":[],"task_id":"crb_papers.q074","task_sha256":"c34219b8aa9595071fae1232f2af4919c9aaf06dc623116c1e56d21fd5ce22fc","timestamp":"2026-10-15T17:09:59.379125Z"}
