The index commonly uses a base year figure of 100, with periods of higher price levels shown by an index greater than 100 and periods of lower price levels by

## Index numbers are values expressed as a percentage of a single base figure. In index terms, output in the two years was 100 and 135 respectively. The arithmetic is straightforward, as shown in Table 1. The following is an example of a base-weighted price index for single-person household consumption of wine and

The deflator is usually expressed in terms of an index, i.e. a time series of index numbers. Percentage changes on the previous year are also shown.

Today, lets talk about indexing, a technique used to compare changes in values over time. What is indexing? Lets say you want to compare prices of Gold & Coffee over last few years. Gold price in 2011 (oct) is $1,655 per ounce. And now (sept 2012) it is $1,744. Like wise, Silver price in 2011 is $32.06 and in 2012 it is $33.61. How do we compare such diverse numbers? Enter indexing. First we The index is then calculated by dividing the price of the basket of goods and services in a given year (t) by the price of the same basket in the base year (b). This ratio is then multiplied by 100, which results in the Consumer Price Index. In the base year, CPI always adds up to 100. This becomes obvious if we look at our example. An index number is the measure of change in a variable (or group of variables) over time. It is typically used in economics to measure trends in a wide variety of areas including: stock market prices, cost of living, industrial or agricultural production, and imports. Index numbers are one of the most used statistical tools in economics. A price index is a series of numbers used to show general movement in the price of a single item, or a set of goods. 5, over time. Thus, insofar as every good has a price that changes . 4. For instance we can say ‘a 5% real increase’ without a base year, but ‘a £5 million real increase’ needs a base A Consumer Price Index of 158 indicates 58% inflation since 1982, while a CPI index of 239 would indicate 139% inflation since 1982. The commonly quoted inflation rate of say 3% is actually the change in the Consumer Price Index from a year earlier.

## 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.
