How is worker age determined?
Worker age is determined by matching 2006 workers with historical PFD files. Only those workers with age data are used to determine the percent of workers older than age 45 or 50. Occupations with a significant number of nonresident workers will have less reliable age information since age data is not available for nonresident workers.
