New Delhi (Agencies): The government will come up with two new series of monthly consumer price inflation this month—rural and urban—Chief Statistician TCA Anant stated.

"The two new series of consumer price index, one for rural and other for urban households, would be launched by this month," said Anant.

The two new index series would be later clubbed into a national consumer price index (CPI-N), which would become the basis for fixing dearness allowance and pay structure, said an official closely involved with development.

Presently, the pay commissions and government use Consumer Price Index for Industrial Workers (CPI-IW) for determining dearness allowance and fixing pay structures.

The national CPI, which has been made more capturing by updating and spreading the basket, will highlight all aspects of economy in a single window, the official said.

The government has decided to make CPI-National applicable for the seventh pay commission.

The figures for CPI-Urban would be collected by the National Sample Survey Organisation (NSSO) whereas for CPI-rural the Ministry of Statistics and Programme Implementation has made arrangements with the postal department for collection of price data from villages.

There are four CPI inflation series—CPI for industrial workers, CPI for agricultural and rural labourers and CPI for urban non-manual employees. Moreover, wholesale prices are measured by WPI index.

"The details of this launch would be divulged at a Press meet being held on Monday after the inauguration of four- day long Commonwealth Statisticians Conference here," he said.

Retail inflation for items consumed by industrial workers increased to 9.47 per cent in December 2010 from 8.33 per cent in the previous month, mainly due to dearer food cost. The rate of price rise has been a concern for both the government and the common man.

The wholesale price index based inflation increased to 8.43 per cent in December from 7.48 per cent in the previous month. WPI food inflation rose to 17.05 per cent for the week ended January 22, on account of rising vegetable prices, particularly, onion.
