Explanation:  

It presents that first comprehensive, long-run payroll knowledge on Swedish middle-class employees ere the twentieth century. Our data cover, for example, academy teachers, instructors, assistants, policemen and porters in Stockholm and Sweden, ca. 1830–1940.

We utilise the current data to analyse the annual incomes of these middle-class workers with the annual incomes of farmworkers, uneducated production operators and manufacturing workers.
