In the Indian administrative framework, the Economic Census and various sample surveys act as the primary tools for capturing data on the unorganized sector, entrepreneurial activities, and household characteristics. While National Income accounting provides the “macro” view of the economy, these censuses and surveys provide the “micro” granular data necessary for targeted policy intervention and base-year revisions of GDP.
The Economic Census (EC)
The Economic Census is a complete enumeration of all entrepreneurial units (establishments) located within the geographical boundaries of India. It provides a comprehensive inventory of the economy, covering both agricultural (excluding crop production) and non-agricultural sectors.
Key Objectives of the Economic Census
- Creating a Sampling Frame: The primary purpose is to develop a Business Register and a sampling frame for follow-up surveys like the Annual Survey of Industries (ASI) and various NSSO rounds.
- Mapping Unorganized Sectors: It captures data on establishments that are not covered under the Factories Act, 1948, providing insights into the “hidden” part of the Indian economy.
- Geographic Distribution: It identifies the regional concentration of specific industries, aiding in the development of industrial clusters.
Historical Timeline and Authority
The Economic Census is conducted by the National Statistical Office (NSO) under the Ministry of Statistics and Programme Implementation (MoSPI).
| Census Round | Year | Notable Feature |
| First EC | 1977 | Covered only non-agricultural establishments. |
| Second EC | 1980 | Conducted along with the House-listing operations of the 1981 Population Census. |
| Sixth EC | 2013 | Highlighted the massive role of proprietary and self-employed units in India. |
| Seventh EC | 2019-21 | First digital census using a dedicated mobile application and IT platform (implemented by CSC e-Governance Services India Ltd). |
Major Economic Surveys for National Accounting
While the Economic Census is a total count, several sample surveys provide high-frequency data on specific economic variables.
Annual Survey of Industries (ASI)
The ASI is the principal source of industrial statistics in India for the organized manufacturing sector.
- Coverage: It covers factories registered under Sections 2(m)(i) and 2(m)(ii) of the Factories Act, 1948, where manufacturing processes are carried out with or without the aid of power.
- Data Points: It provides information on capital investment, employment, wages, input costs, and value of output.
- Role in GDP: It is the primary data source for calculating the Gross Value Added (GVA) for the “Registered Manufacturing” sector.
Periodic Labour Force Survey (PLFS)
Launched in April 2017, the PLFS replaced the earlier quinquennial (five-yearly) employment-unemployment surveys.
- Frequency: Quarterly for urban areas (Current Weekly Status) and Annual for both rural and urban areas (Usual Status and CWS).
- Metrics: It tracks the Labour Force Participation Rate (LFPR), Worker Population Ratio (WPR), and Unemployment Rate (UR).
Household Consumer Expenditure Survey (HCES)
Conducted by the NSSO, this survey captures the consumption patterns of Indian households.
- Significance: It is used to determine the “basket of goods” for the Consumer Price Index (CPI) and to estimate poverty lines.
- Recent Update: The HCES 2022-23 results showed a significant shift in spending, with the share of food in total expenditure declining in both rural and urban India, indicating a rise in discretionary spending.
Differences Between Census and Surveys
| Feature | Economic Census | Economic Surveys (NSSO/ASI) |
| Coverage | Complete enumeration (Total count). | Sample-based (Representative group). |
| Depth | Broad but basic info on all units. | Deep and detailed info on specific parameters. |
| Purpose | To create a frame/directory. | To estimate trends and rates (e.g., inflation, unemployment). |
| Cost & Time | Very high; conducted every 5-10 years. | Lower; conducted annually or quarterly. |
Sector-Specific Surveys
All-India Survey on Unincorporated Sector Enterprises (ASUSE)
This is a critical survey that focuses specifically on the vast informal sector in India. It covers non-agricultural establishments in manufacturing, trade, and other service sectors that are not incorporated (i.e., not registered under the Companies Act).
Services Sector Surveys
Given that services contribute over 50% to India’s GVA, the NSO conducts specific surveys to capture the production and price changes in various service industries, which are often harder to measure than physical goods.
Facts and Trivia for UPSC Aspirants
- Establishment vs. Enterprise: In the Economic Census, an “establishment” refers to a unit situated in a single location and involved in one primary economic activity. An “enterprise” can have multiple establishments across different locations.
- The Seventh EC Innovation: The 7th Economic Census utilized Geo-tagging for the first time to map the exact location of every entrepreneurial unit in India.
- The “Sample Registration System” (SRS): While not purely economic, it provides vital data on birth and death rates, which are essential denominators for Per Capita Income calculations.
- Exclusions: Crop production and plantation, public administration, defense, and compulsory social security are typically excluded from the Economic Census as they are covered by other administrative records.
- National Business Register: A key outcome of the recent Economic Censuses is the creation of a dynamic National Business Register that syncs with GST and EPFO data for real-time economic monitoring.
