The consumer price index, typically known just as the CPI, is a crucially important way to measure changes in the cost of living in South Africa – but the way it is calculated has surprising elements.
To arrive at an accurate number, Statistics South Africa (Stats SA) updates its basket of typical household goods every four years.
The current basket from which SA CPI is calculated has 412 products, up slightly from the previous 396.
Price statistics manager at Stats SA, Marietjie Bennet tells Business Insider South Africa that the basket is made using an income and expenditure survey, to figure out what South Africans are buying – and what they aren't.
These products and services are among thosethe statistical authority has just added to the basket because – weird as they seem – Stats SA found to reflect South African spending habits.
Products that Stats SA booted from the basket include electric fans, teapots, blank CDs and DVDs, postal stamps and board games.
