Dun & Bradstreet's database of U.S. organizations with 100 or more employees defines the "universe" described in Training magazine's Annual Industry Report. (Note: There are 155,013 companies in this database. Because Dun & Bradstreet does not include companies with fewer than 100 employees, we do not report on budget activity at those organizations.) Because we over-sample bigger companies, a weighting formula is applied to our raw data to correct for that bias. When we report findings for the overall survey, or break down data by industry, responses from small organizations are weighted more heavily than those from large organizations.
