The Relationship Between Firm Size and Age of Workforce: A Cross-industry Analysis for Canada

Using an employer–employee matched dataset of administrative tax records on most Canadian firms and the full populations of their workers, this paper documents relationships between firm size, industry, and the typical ages of firms’ workforces. In particular, the paper considers both differences in levels for the calendar years 2003 to 2010 inclusive, as well as changes in the age composition of firms’ workforces over this time as observed in a longitudinal analysis.
