How is this data produced?
The primary Gini coefficient at state-level is computed based on the distribution of households' gross monthly income, where:
- Gini coefficient values are bounded within 0 and 1, with higher values indicating greater income inequality.
- A value of 0 indicates perfect equality (i.e. that every household has the same income).
- A value of 1 indicates total inequality (i.e. that 1 household earns all the income while all others earn nothing).
Because the computation of the Gini coefficient relies on household income data, Malaysia's Gini coefficient statistics are produced and published together with statistics on household income derived from the Household Income and Expenditure Survey (HIES), which is conducted at least twice within any 5-year period. For full details on the methodology, especially the computation of the PLI and its evolution and nuances, please refer to the technical notes.
What caveats I should bear in mind when using this data?
Given that the data is produced from surveys spanning over half a century, it should be noted that:
- Kuala Lumpur was gazzeted as a Federal Territory on 1 February 1974. Accordingly, data for W.P. Kuala Lumpur is only available from 1976. Prior to that, data for residents of W.P. Kuala Lumpur was included under Selangor.
- Labuan was gazetted as a Federal Territory on 16 April 1984. However, due to limitations in sampling, data for W.P. Labuan is only available from 2007. Prior to that, data for residents of W.P. Labuan was included under Sabah.
- Putrajaya was gazzeted as a Federal Territory on 1 February 2001. However, due to limitations in sampling, data for W.P. Putrajaya is only available from 2007. Prior to that, data for residents of W.P. Putrajaya was included under Selangor.
