Does anyone know what changes they did in 2000 and 1992?

A key indicator of private home prices is being reviewed to ensure that it continues to accurately reflect values in Singapore.

The study, which The Straits Times understands began last year, could involve revising the way the Urban Redevelopment Authority's (URA) quarterly index is computed. It is believed that no concrete decisions have yet been made to overhaul the methodology.
The index was last modified in 2000, after changes in 1992.

The URA, which is the public agency responsible for tracking price trends, is undertaking the study to look at other methods and to test the robustness of its own index, a spokesman said yesterday.
