Private consumption makes up roughly 60 percent of total GDP. Therefore, a timely and precise assessment of the developments in private consumption is deemed important for making judgments on business cycles in the macroeconomy.

From this viewpoint, the Research and Statistics Department of the Bank of Japan provides research data titled "Consumption Activity Index (CAI)" on a regular basis. The CAI is compiled by using a variety of sales and supply-side statistics on goods and services as its source statistics and is provided as a measure for capturing short-term consumption activity on both monthly and quarterly bases. The CAI traces movements of consumption in the household side of the economy, much like those in the Annual Report on National Accounts (ARNA) -- which represents consumption activity in Japan in the most comprehensive manner -- but is made available in a more timely fashion. The CAI shows only small fluctuations emanating from samples rotations, and also exhibits a high correlation with a number of confidence survey measures.

Various series of the CAI -- such as nominal and real indexes, indexes with/without adjustments of travel balance, and a breakdown by type of goods/services -- are available to meet various analytical needs.

The data are, in principle, released at 2:00 p.m. on the fifth business day of each month; however, this release schedule is subject to change.

Details on the compilation methodology are available in the following research papers.
