Gallup's Economic Confidence Index is a composite of two questions that Gallup asks daily of a nationally representative sample of 500 adults, aged 18 and older, and reports weekly based on approximately 3,500 interviews. One question asks Americans to evaluate current economic conditions; the other measures their perceptions of whether the economy is getting better or getting worse. The two questions have equal weight in the index, and are reported without revisions or seasonal adjustments. They can also be analyzed separately, providing insight into changes in the overall index. The survey is conducted with respondents contacted on landlines and cellphones
In today's fast-moving, information-loaded environment, consumer attitudes can, and often do, change multiple times between the beginning and the middle or end of a month, and the Gallup index keeps up with these fluctuations. Followers of the metric therefore develop a keen understanding of the degree to which various economic and political events -- including monthly BLS jobs reports, major changes in the stock market, and significant congressional budget actions -- affect consumer attitudes.
