What are index numbers? Index numbers are a useful way of expressing economic data time series and comparing / contrasting information. An index number is a figure reflecting price or quantity compared with a base value. The base value always has an index number of 100. The index number is then expressed as 100 times the ratio to the base value. To simply things, the economist changes the $33,125 to the base number, which is usually set at 100. All other numbers are similarly scaled down. In this example, the value for the second year is changed from $34,781 to 1.05, or a 5% increase from the prior year.
