Note: This year the sample design was revised by weighting the sample to reflect the distribution of firms reported by the U.S. Census. Data from the U.S. Census indicated that the Dun & Bradstreet sample frame used in years past had overestimated the influence of small employers (who have a relatively low offer rate) on the total results.
