Basket of goods and services and weighting pattern
The rate of price increase does not only depend on how the prices change. Another important factor is the weights with which the price trends of the individual types of goods are included in the overall index. The weighting pattern shows which kind of good enters with what weight into the overall index.

The basket of goods of the consumer price index is made up of about 700 goods. For each type of goods - for instance, for books, cinema tickets or for petrol - the price trend is calculated. The entire consumer price index is a weighted average of the price trends for all about 700 types of goods.
