A long-term database describing the structure of labor input and labor compensation in the Japanese economy from 1955 to 2023.
For each year, labor input is categorized into a cross-classification of 20,240 attributes defined by sex (2 categories) × educational attainment (4 categories) × age group (11 categories) × employment status (5 categories) × industry (46 categories). Each attribute includes information on the number of workers (N), average hours worked (h), and wage rate (w).
