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.\",\n \"columns\": {\n  \"city\": \"str\",\n  \"YEAR\": \"float64\",\n  \"occ\": \"str\",\n  \"name\": \"str\",\n  \"govt\": \"float64\",\n  \"pop\": \"float64\",\n  \"treat_assign\": \"float64\",\n  \"treat_actual\": \"float64\",\n  \"bandwidth\": \"float64\"\n }\n}"}
