The Indian government reports the benchmark wholesale price index for April 2012 was at 7.23%, up from 6.89% in March. The wholesale price index measures bulk sales between corporations and is considered a better measure than the old consumer price index, which lacks representative data from all regions. The wholesale price index does not include services, which make up half of the economic output. A new CPI has been introduced, but more data has to be gathered for it to become a dependable measure of inflation. Core inflation excluding food and energy, which focusses on the manufacturing sector, increased 5.1%.
