”Boot(1000)” means that a different life table was calculated for each bootstrap sample. “CHS data” means that the same life table was used for all calculations. For lines 4c, 5c and 6c, the U.S. life table was used. Standard errors for Sullivan variance came from Table 1. Column 7 is the ratio of the Sullivan standard error to the Bootstrap standard error.
