The Retail Price Index

Other Goods
Man does not live by bread alone. He needs many other things apart from food. Your family will spend money on a variety of items.

  1. Write down a dozen items that your family buys apart from food.
  2. Try to classify these items into a smaller number of categories, such as travel or clothing.
  3. Try to estimate how much, out of every £1000 spent, your family spends on each category.

 

A Clothing Index
In earlier sections you have found how food prices have changed, measured as an index number.

  1. Write down in a few sentences how you did this. (A flow chart may help you.)
  2. Choose two categories, clothing and one other, from your list. Write down in a few sentences how you would estimate the change in prices of items in these categories. Consider the weighting of individual items.

One family has no children, another has two young children, while a third family has six children of different ages.

  1. How would a clothing index be different for these three families?

 

Mr Hill's Budget
Mr Hill made a careful study of how his family spent its money in 1977. For every £1000 spent, he recorded the
amounts spent on each major category in Table 6. He. is a typical family.

Catagory 1977

Food 233 107  
Alcoholic drink 85 109  
Tobacco 48 115

Fuel and light 60 111  
Durable household hoods 64 112  
Clothing and footware 80 110  
Transport and vehicles 140 111  
Miscellaneous goods 70 113  
Services 56 112  
Meals boought and eaten out 51 116  

Table 6 - Mr Hill's spending.

  1. For each group of items in Table 6 (except food and clothing), write down a few items it may contain. For example, 'Housing' includes rent, mortgages, rates and repairs in the home.
  2. Copy Table 6.
  3. Find the 1978 costs of each category. (Use the method in Section B4.)
  4. Total separately the 1977 costs and the 1978 costs.
  5. Find the combined price index for 1978, with 1977 as the base year.

The combined index of all major categories is called the RETAIL PRICE INDEX.

The Department of Employment calculates the Retail Price Index each month, using January 15, 1974, as the base time. They find out the prices in many shops throughout the country. Altogether there are about 350 items on their list. They calculate individual item indices and combine them to find category price indices. From the Family Expenditure Survey carried out annually, the amount spent in each category is found, and hence the Retail Price Index is calculated.
