The Index of Current Economic Conditions (ICC) is a sub-index in the University of Michigan Surveys of Consumers.
It is published by the Survey Research Center in the Institute for Social Research. Its siblings are the headline Index of Consumer Sentiment (ICS) and the outlook Index of Consumer Expectations (ICE).
It covers a national sample of American households in the 48 coterminous states plus DC, excluding Alaska and Hawaii. It uses a rotating panel with telephone interviews through the month, about 1,000 interviews and about 50 core questions. It tracks attitudes and expectations, not actual spending or the inflation rate itself.
Inflation expectations sit alongside it and do not enter it, and it carries no buy or sell threshold.
