The Collection of Statistics (Central) Rules, 1959 framed under the 1953 Act provided for, among others, a comprehensive Annual Survey of Industries (ASI) in India. This survey replaced both the CMI (Census of Manufacturing Industries) and SSMI (Sample Survey of Manufacturing Industries). The ASI was launched in 1960 with 1959 as the reference year and is continuing since then except for 1972. For ASI, the Collection of Statistics Act 1953 and the rules frame there-under in 1959 provides the statutory basis. ASI Time-Series Data was collected from 1998-99 to 2007-2008.
The Annual Survey of Industries (ASI) is the principal source of industrial statistics in India. It provides statistical information to assess changes in the growth, composition and structure of organised manufacturing sector comprising activities related to manufacturing processes, repair services, gas and water supply and cold storage. The Survey is conducted annually under the statutory provisions of the Collection of Statistics Act 1953, and the Rules framed there-under in 1959, except in the State of Jammu & Kashmir where it is conducted under the State Collection of Statistics Act, 1961 and the rules framed there-under in 1964.
Kind of Data
Sample survey data [ssd]
Unit of Analysis
The primary unit of enumeration in the survey is a factory in the case of manufacturing industries, a workshop in the case of repair services, an undertaking or a licensee in the case of electricity, gas & water supply undertakings and an establishment in the case of bidi & cigar industries. The owner of two or more establishments located in the same State and pertaining to the same industry group and belonging to census scheme is, however, permitted to furnish a single consolidated return. Such consolidated returns are common feature in the case of bidi and cigar establishments, electricity and certain public sector undertakings.
- v2.1: Edited, anonymous dataset for public distribution.
The scope of the Annual Survey of Industries includes:
Primary Characters :- Number of Factories, Fixed Capital, Working Capital, Invested Capital, Outstanding Loans, Number of Workers, Mandays-Workers, Number of Employees, Mandays-Employees, Total Person Engaged, Wages to Workers, Total Emoluments, Old Age Benefits, Social Security Benefits, Other Benefits, Fuels Consumed, Material Consumed, Total Inputs, Products, Value of Output, Depreciation, Net Value Added, Rent Paid, Interest Paid, Net Income, Net Fixed Capital Formation, Gross Fixed Capital Formation, Additon in Stock of - (i) Material, Fuels etc., (ii) Semi Finished Goods, (iii) Finished Goods, (iv) Total, Gross Capital Formation, Profits
The ASI extends to the entire country
The ASI covers all factories registered under Sections 2m(i) and 2m(ii) of the Factories Act, 1948 i.e. those factories employing 10 or more workers using power; and those employing 20 or more workers without using power. The survey also covers bidi and cigar manufacturing establishments registered under the Bidi & Cigar Workers (Conditions of Employment) Act, 1966 with coverage as above. All electricity undertakings engaged in generation, transmission and distribution of electricity registered with the Central Electricity Authority (CEA) were covered under ASI irrespective of their employment size. Certain servicing units and activities like water supply, cold storage, repairing of motor vehicles and other consumer durables like watches etc. are covered under the Survey. Though servicing industries like motion picture production, personal services like laundry services, job dyeing, etc. are covered under the Survey but data are not tabulated, as these industries do not fall under the scope of industrial sector defined by the United Nations. Defence establishments, oil storage and distribution depots, restaurants, hotels, café and computer services and the technical training institutes, etc. are excluded from the purview of the Survey.
From ASI 1998-99, the electricity units registered with the CEA and the departmental units such as railway workshops, RTC workshops, Govt. Mints, sanitary, water supply, gas storage etc. are not covered, as there are alternative sources of their data compilation for the GDP estimates by the National Accounts Division of CSO.

A new sampling design has been adopted from ASI 2006-07 is as under:
i) Units with 100 or more workers will be categorized as census sector and the rest of the units will be treated as sample sector, without any change in the existing criteria;
ii) In the sample sector, the units will be stratified at 4 digit level of NIC-04 in each State separately and 1/5th of the units in each strata will be selected circular systematically for coverage in each ASI subject to a minimum sample size of 6 units in each stratum;
iii) This design will ensure that the whole universe of units is covered in five years;
iv) The classification of the units in the frame into census and sample sectors should be done in the beginning of the 5-year cycle and it should not be disturbed during the course of the cycle;
v) At the end of the cycle when the data on the all the units in the frame become available the frame should be updated and then the composition of census and sample sector should be re-drafted;
vi) In respect of the new units getting registered each year of the last 4 years in the 5-year cycle, a supplementary frame has to be prepared for each year and units for coverage from this supplementary frame of each year may be selected using the same criteria as was applied to the main frame.
Deviations from the Sample Design
The sampling design has undergone changes in the past on several occasions.
Dates of Data Collection
Data Collection Notes
Data for the ASI are collected through a comprehensive schedule. In the initial rounds, the schedule sought particulars relating to manufacturing activity only. Over the years, additions were made to meet the specific data requirements of various organisations. By 1973-74, the schedule consisted of five Parts: Part I on manufacturing, Part II on labour turnover, Part III on stocks & consumption of components and accessories in small scale sector, Part IV on construction expenditure and Part V on indirect taxes, sales, subsidies and capacity of power equipments installed. It was felt that the ASI schedule had become too unwieldy and complicated. So a modified schedule with three parts on manufacturing, labour and construction was adopted with effect from ASI 1974-75. Further modifications in the schedule were carried out in 1987-88, and again in 1997-98. Part III schedule relating to construction has been discontinued from 1998-99. The schedule from ASI 2003-04 also incorporated some minor changes.

Ministry of Statistics and Programme Implementation
Data submitted by the factories undergo manual scrutiny at different stages.
1) They are verified by field staff of NSSO from factory records.
2) Verified returns are manually scrutinized by senior level staff before sending to data processing centre.
3) At the data processing centre these are scrutinized before data entry.
4) The entered data are subjected to computer editing and corrections.
5) Tabulated data are checked for anomalies and consistency with previous results
Scrutinizing officer checks the following points:
1. Examine the Industry Code with reference to production/Process and check whether Industry Code is reported in 5digit NIC 2008 against item 5 of Block A.
2. Checks whether Proper remarks for all important parameters such as GVA, Working Capital, wage rate, number of workers, distributive expenses, depreciation etc. are given.
3. Check basic entries where Output/ Input ratio is less than 0.5.
4. Check Ratio of distributive expenses to gross sales where this ratio exceeds 20%.

The ASI data at factory level are strictly confidential and are to be used only for statistical purposes after aggregation.
The collection of Statistics Act assures confidentiality of the data to the factories.
To ensure confidentiality, data of factories with less than three units in an industry are merged. Location of the unit is also not divulged in the micro data.
