Over the years included in this study, the percentage of filings including enrollment data grew continuously (Table 11). In the individual market, this percentage increased from 50.1 percent in 2008 to 80.0 percent in 2011. In the small group market, corresponding figures increased from 83.5 percent to 92.9 percent. However, the nature and apparent quality of data were inconsistent throughout the study period, with carriers reporting a mix of contracts held and covered lives, and many reporting identical enrollment figures for different books of business.
