SRI-Hitotsubashi consumer purchase indices, are calculated based on the POS data of 4000 stores, such as supermarkets, convenience stores, drug stores, and large retail stores. In SRI-Hitotsubashi consumer purchase indices, we break down changes in consumer expenditures into price, quantity, and the effect of product turnover, which are shown in "Consumer-purchase Expenditure Index", to see the change in the price of consumer purchases, which are shown in "Consumer-purchase Price Index ", to see the change in the quantity of consumer purchases "Consumer-purchase Quantity Index ", to see the effect of products turnover in consumer purchases, which are shown in " Consumer-purchase Turnover-effect Index ".
From May 28, 2015, we published "Unit Value Price Index (Preliminary)". The indexes can capture the impact of capacity changes and replacement of new products and the old products on the price inflation.
Note: Both expenditure and price indices are net of tax (Value Added Tax). Information of perishable food, lunch, convenience store coffee, etc. are not included.
