  2. The measure of occupational hazards is drawn from a sample of the 1970 Census which included occupational characteristics from the Dictionary of Occupational Titles (DOT). An indicator for a DOT occupation having hazards was averaged within each 1980 Census occupation code; we then convert this percentage measure to a Z-score
  3. Tenure is defined as the total number of weeks an individual has worked in a given occupation across all employers. The total number of jobs is measured since the last interview
  4. Wages are measured in constant dollars
