|Dissemination of terms and
conditions under which
official statistics are
produced, including those
relating to the confidentiality
of individually identifiable
0.1.1 Responsibility for collecting, processing, and disseminating statistics
In accordance with the Government of India (Allocation of Business) Rules, 1961, as amended from time to time, it is the responsibility of the Ministry of Labour to compile and release the data on the CPI for Industrial Workers and the data on the CPI for Agricultural/Rural Labourers. Further, it is the responsibility of the Ministry of Statistics and Programme Implementation to compile and release the data on the broad based CPI (Rural,Urban,Combined).
0.1.2 Data sharing and coordination among data producing agencies
There is no ongoing data sharing between the divisions in the Labour Bureau responsible for the CPI-IW and CPI-AL/RL or between the Labour Bureau and Central Statistics Office, which compiles CPI.
0.1.3 Confidentiality of individual reporters' data
The confidentiality of individual respondents' data is maintained through Data Dissemination Policy approved by Union Government of India. The index series are published on a level of aggregation that prevents direct or indirect disclosure of individual data. Group,sub group indices of CPI(R,U,C) and item level CPI(C) are available on the website of Ministry of Statistics and Programme Implementation.
0.1.4 Ensuring statistical reporting
There is no formal legal authority to obtain requested data from respondents. Data are collected on a voluntary basis by making visits.
0.2.1 Staff, facilities, computing resources, and financing
The number of the staff is adequate to perform the required tasks. Senior as well as junior staff is knowledgeable about CPI concepts and methods of index calculation. There is high awareness of the need to ensure as far as possible consistency between the concept and purpose of the index and the methods applied. Also considerable efforts are devoted to ensure a robust production process in order to ensure the collection, compilation and publication of the index on a timely basis.
Further, sufficient computer resources and financial resources for compiling the statistical series have been allocated for performing the required tasks.
0.2.2 Ensuring efficient use of resources
Rules of data validation as well as index compilation procedures and data file formats are harmonized so that the reporting of prices, validation of the data and compilation of indices can be undertaken efficiently and timely.
0.3.1 Monitoring user requirements
New or emerging data requirements as well as methodological issues are deliberated and decisions taken in the meeting of the Technical Advisory Committee on Statistics of Prices and Cost of Living (TAC on SPCL). Meetings of this Committee are periodically convened with the main users of the index to review existing statistical series and methods. Users are also welcome to raise questions and to give suggestions to the concerned Departments.
0.4.1 Quality policy
Officers and staff are carefully instructed to comply strictly with all rules regarding integrity and confidentiality to prevent any influence from other parties. Consistency in concepts as well as in published data are also an issue of high priority as even very small discrepancies or ambiguities in the published indexes may have considerable effect as many wages and allowances are adjusted according to the different CPIs. Staff are, therefore, trained and instructed to follow rules and procedures in the compilation of the index to ensure the quality.
0.4.2 Quality monitoring
Measures are in place to monitor the quality of the various statistical stages. Through the regional offices and the price supervisors, efforts are continuously made to ensure that the guidelines for price collectors are followed. The processing of data is carefully checked each month according to a fixed schedule for checking and validation of data, both manually and automatically. Indexes down to item level are checked and cross-checked across item groups and centers. Before publication the final index figures are doubly checked to prevent mistakes.The TAC on SPCL provides guidance and recommendations on the quality of the index series and on strategies for improving data production. Although this body is advisory, its recommendations are followed in practice.
1.1.1 Impartiality of statistics
The Government of India (Allocation of Business) Rules, 1961 address the general need for the professional independence of the data producing agency and prohibits interference from others, including other government agencies, in the compilation and/or dissemination of the Consumer Price Indices. There is thus a long standing tradition of non-interference and impartiality.
1.1.2 Selection of sources, methodology, and modes of dissemination
The choice of source data and statistical techniques for sampling, processing and validation is based solely on statistical considerations. Methodological documents are also available in respect of these indices on homepages of Ministry of Statistics and Programme Implementation [for CPI (Rural,Urban,Combined)] and the Labour Bureau [for CPI (IW) and CPI(AL/RL)].
1.1.3 Commenting on erroneous interpretation and misuse of statistics
Efforts to prevent misinterpretation or misuse of statistics are made by providing explanatory materials and documentation.
1.2.1 Disclosure of terms and conditions for statistical collection, processing, and dissemination
The terms and conditions under which the index is compiled and disseminated, are publicly available in homepages of Ministry of Statistics and Programme Implementation [for CPI (Rural,Urban,Combined)] and the Labour Bureau [for CPI(IW) and CPI(AL/RL)].
1.3.1 Guidelines for staff behavior
Guidelines for staff behavior are outlined in the Civil Services Conduct Rules, which are implemented and followed in the daily work in the data producing agencies and in the contact with users and respondents.
|Identification of internal
government access to data
1.2.2 Internal governmental access to statistics prior to release
The Index is released through Press Note at fixed date and time. Pre release access of CPI (R,U,C) is given only to the Ministry of Finance, about one hour before the release in sealed cover.

detail, reconciliations with
related data, and statistical
frameworks that support
and provide assurance of
4.2.1 Internal consistencyBoth the center-level and the all-India CPIs are consistent with the weighted average of the sub-indexes of the index. The overall all-India CPI is also consistent with the weighted average of center-level indexes.
4.2.2 Temporal consistencyConsistent time series data till the latest released index are available on the concerned Department’s website, including linking factors on center-level and for all-India between the new and the old CPI series.
4.2.3 Intersectoral and cross-domain consistencyDue to the specific index population coverage, the three CPIs – CPI-IW, CPI-AL/RL and CPI(Rural,Urban,Combined) are not consistent or reconcilable with each other. Divergences in the growth rates have been found in the three CPIs.
