Among cities with observed reform status at both censuses, how did adopting a civil service commission after 1930 and by 1940 affect the change from 1930 to 1940 in the share of blue-collar city jobs held by foreign-born white residents, compared with cities that had not adopted by 1940, adjusting for the city's foreign-born white population share?

   Among cities with observed reform status at both censuses, how did adopting a civil service commission after 1930 and by 1940 affect the change from 1930 to 1940 in the share of blue-collar city jobs held by foreign-born white residents, compared with cities that had not adopted by 1940, adjusting for the city's foreign-born white population share?

   | Variable Name | Description | | --- | --- | | treat | Binary indicator equal to 1 if the municipality had established a municipal civil service commission (merit-based personnel system) by the given census year; 0 if not yet established. Values are weakly increasing over time within a city. Sourced primarily from U.S. Civil Service Assembly municipal surveys (1937, 1940, 1943) and corroborated by state statutes; may be missing (blank/NA) where adoption year could not be determined. | | pop_prop | Proportion (0–1) of the city’s residents who are foreign-born whites in that census year. Constructed from full-count decennial U.S. Census microdata using birthplace (foreign-born) and enumerated race (white). Available for decennial years 1850–1940 except 1890 (destroyed census). | | govt_prop | Proportion (0–1) of blue-collar municipal government employees who are foreign-born whites in that census year. Computed from full-count decennial U.S. Census microdata by identifying residents employed in local public administration and classifying blue-collar occupations (e.g., craftsmen, mechanics, service workers, laborers); police and fire personnel are excluded due to distinct recruitment regimes. Counts reflect resident workers and assume city employment generally coincides with residence in this era. | | city | Municipality name and two-letter state abbreviation in the standardized format “city, st” (e.g., “aberdeen, sd”). Standardization facilitates consistent tracking across sources and decades; cities with the same name are distinguished by state. | | YEAR | Decennial census year for which measures are calculated (integers from 1850 to 1940; 1890 absent due to the lost census). | Dataset Context: This dataset follows U.S. municipalities at ten-year intervals from the mid-19th to early-20th centuries, a period spanning patronage-based municipal staffing through the widespread diffusion of merit-oriented civil service systems. Municipal adoption of civil service rules was recorded by the U.S. Civil Service Assembly in nationwide surveys conducted in 1937, 1940, and 1943 and supplemented by state-level statutes that, in many cases, mandated adoption using population thresholds. The “treat” indicator reflects whether a city had a functioning municipal civil service commission by a given census year; because commissions, once established, typically persisted, the indicator does not toggle back to zero for later years. Demographic and employment composition measures are derived from the full-count decennial U.S. Censuses (1850–1940, with 1890 unavailable). The census enumerated every resident and captured birthplace, race, industry, and occupation, allowing identification of local public administration workers and classification of blue-collar positions. Blue-collar categories include craftsmen, mechanics, service workers, and laborers; police and fire employees are excluded because their hiring, promotion, and protection rules often followed distinct legal frameworks. Because the census does not name employers, municipal employment is inferred from the industry code “local public administration,” and, consistent with transportation realities of the era, employees are assumed to work in the municipality where they reside. The civil service systems cataloged here typically introduced commission oversight of hiring, promotion, and termination in “classified” services, commonly relying on publicly advertised examinations and shortlists (e.g., a “rule of three”). “Unclassified” roles (e.g., department heads, certain temporary staff) fell outside commission rules, and the scope of coverage varied across cities and over time. City names are standardized to “city, st” to harmonize historical references across sources and decades. Shares are expressed as proportions between 0 and 1 and are calculated at the city–year level to align with the decennial timing of the underlying census enumerations.
