Wage distribution within the Swedish State Railways, 1877–1951: Material and methods.
For nine decades, the Swedish State Railways (SJ) produced wage records containing all its permanent employees. SJ employed more people than any private employer in Sweden, and the records contain individual-level information across hundreds of occupations: full name, yearly wage, occupational status, year and date of birth, occupational status, time of employment at SJ, etc. This paper serves as a background to a project on wage distribution within SJ, with the aim of tracking the development of, on the one hand, occupational or class-based wage inequality and, on the other, gender-based wage inequality. In this paper, we present the source material in detail, discuss its strengths and weaknesses, and describe the methods used to develop and process the wage records into data. Special attention is given to the adoption and application of HISCLASS, the historical, international social class scheme.
