Operational Definitions
The percentage of total household income earned by the lowest five deciles of the distribution of monthly household income of domestic households, based on the General Household Survey which covers the land-based non-institutional population of Hong Kong.
All figures are collected from Census and Statistics Department since 1986. Figure for 1981 is extracted from Hong Kong 1991 Census Main Report and is therefore based on census data. Comparison across years is therefore subject to statistical error.

Further to the reply from C &SD (15 May 2008), the data previously collected by HKCSS are compiled from the results of the General Household Survey (GHS).  A recent review on the quality of such data has been conducted.  Given the smaller sample size of the GHS and thus its limitations in identifying sufficient number of households in the two tails of the distribution, the estimates concerned are considered not reliable enough and they are no longer released.  Users are suggested to refer to the results of the population census/by-census for statistics on income distribution.
