JANUARY ISSUE OF MONTHLY DIGEST OF STATISTICS
The Hong Kong Monthly Digest of Statistics issued today contains a
special review which discusses the ratio-to-moving average method of making
seasonal adjustment to the General Consumer Price Index.
It is one in a series of reviews on special subjects of interest
prepared for public pursuance by the Census and Statistics Department.
Introducing the review article, a spokesman for the department said:
"As the General Consumer Price Index is influenced by seasonal factors,
direct comparison of the index for any one month with that for any other month
can give a misleading impression of the way in which prices tended to move
over the period concerned,
"For this reason, it is advisable to adjust the General Consumer
Price Index for seasonality. The ratio-to-moving average method is one of the
noot widely used in measuring seasonal variation."
The Monthly Digest of Statistics is available from the Government
Publications Centre, Star Ferry Concourse, Hong Kong, at $5 per copy.
