The Bloomberg Consumer Confidence Index measures Americans' perceptions of the economy, personal finances and their desire to purchase goods and services. It is derived from telephone interviews of roughly 250 adult consumers per week, and is based on a four-week moving average of 1,000 responses.
It is calculated by taking the percentage of negative views and positive views, and dividing the difference by 3. The results can range from 100 to minus 100.
