Most of the September gain was among households with incomes in the bottom third, whose index value of 96.3 was the highest since November 2000. In contrast, the Sentiment Index among households with incomes in the top third lost a total of 8.1% during the past seven months since reaching its cyclical peak of 111.9 in February 2018. This divergence across income subgroups has been observed in past economic cycles and indicates that the expansion has now benefitted nearly all population subgroups.
