Monthly Vintages (Index level, seasonally adjusted. Base period varies across vintages.)

The entire time-series history for each vintage (column) is available to the public at the vintage date shown in the column header.

First-, Second-, and Third-Release Values (Units indicated in the file)

For each observation, we report the appropriate values from each vintage that correspond with the statistical agency's first-, second-, and third-release values for that observation. (We also report the values as they appear in the most recent vintage available when we ran our programs.)
