The source writes:

The index is designed to reflect all non-institutional households in the Republic of Mauritius (foreign and national born). The calculation follows ILO standards (CPI Manual).

The basket composition used for calculating CPI uses data obtained at by the Household Budget Survey (HBS) that was conducted from January to December 2017. HBS included data from 7,000 households. The weights are fixed and updated every 5 years after HBS is updated.

The basket of commodities are classified according to the UN COICOP (Classification of Individual Consumption according to Purpose) at four levels with 12 divisions, 42 groups, 80 classes and 180 items. Goods produced by the household, second hand goods (not including reconditioned motor vehicles) and good received for free are excluded. 

Household consumption expenditure (used to calculation weights) excludes direct taxes (income tax, social security contribution, life insurance premiums, saving bank deposits, disbursement for investors, gambling losses and cash grants to other households). Owner occupied dwellings are excluded.

With regards to CPI weights, consumption expenditure is valued at purchasers’ prices.
The observed prices are transaction prices, that is, those that any member of the public would be paying to purchase the specified goods or services in specific outlets and regions. Any value added tax or excise duty attached to the goods is included.

Prices of perishable items are collected on a weekly basis. Non-perishabke items are recorded once per month between the 12th and 20th. 

The lowest level indices are aggregated according to the Laspeyres formulae. The reliability of data processing is verified by compiling the indices independently in an Excel-based system.

Moody's Analytics supplements

We have back-extended the NSA fundamental over the interval 1962m7 to 1979m12 using the corresponding series from the IMF "International Financial Statistics" (IMFIFSIPCPIUM.IMUS). From the enhanced fundamental, we have constructed an SA counterpart using X-13ARIMA-SEATS.

Yes.

During the revision of weights exercise which usually takes place at intervals of five years, data are gathered from outlets, importers and other stakeholders on new goods/services that need to be included in the updated basket.
