I am wondering whether there is an error with the ASECWT variable in the 2014 ASEC data. Using the weight to create time-series statistics leads to some odd results. As a check, I calculated means for asecwt for several years and the 2014 weight is much larger than adjacent years (the following is Stata output):

. mean asecwt, over(year)

Mean estimation Number of obs = 1,948,983
