For sample persons aged 18 and older who worked at a civilian job last year and who had at least one on-the-job injury last year resulting in medical attention beyond minor first aid, OR inability to do some work activities, OR loss of consciousness, OR transfer to another job, WI1DA reports the day when the first injury happened last year.

Users should combine WI1DA with WI1MO and WI1YR, which reports the month and year when the first injury happened, to get complete information on the date of the first injury last year.

This variable was included in the 1988 Occupational Health supplement.
