Value and volume indexes of sales at retail establishments in Hong Kong. Monthly from 2004, plus predecessors.
Retail sales statistics are primarily intended to measure the sales receipts of goods sold by local retail establishments, for gauging the short-term business performance of the local retail sector. They cover consumer spending on goods, but not on services. They include spending on goods by visitors in Hong Kong but not by Hong Kong residents outside Hong Kong, so are not a comprehensive indicator of overall consumer spending.
Source: The Monthly Survey of Retail Sales (MRS), using a sample of establishments drawn from all the retail establishments registered with the Business Registration Office of the Inland Revenue Department, the Food and Environmental Hygiene Department and the Housing Department.
Industry classification: statistics are compiled based on the Hong Kong Standard Industrial Classification (HSIC) Version 2.0, the 2008 localization of UN ISIC Rev. 2.
Value indices measure the changes in value terms. The volume indexes are deflated by specially constructed price indices and as of 2016 use a chain-linked approach.
The base year (reference period) is updated every five years.
Seasonally adjusted series are produced using the X-12 ARIMA method.
Data are provisional when first published and are subject to revision.
Seasonally adjusted measures are revised each year upon publication of the January period, for the prior three years.
Retail sales show pronounced volatility in the first two months of the year (January and February) due to the variable timing of the Lunar New Year festival.
