Trade statistics within the domestic economy require clear definitions of establishments, turnover, employment and physical activity. This topic is useful for ISS because it connects business statistics, classification and index-number concepts.
1. Scope of trade statistics
Domestic trade statistics can describe establishments, turnover, employment, inventories and transactions. The exact population and business units depend on the statistical operation.
2. Turnover
Turnover is a monetary flow over a specified period. It should not be confused with profit, stock of inventory or physical sales volume.
3. Value and volume
Turnover can change because quantities change, prices change, or both. Volume indicators are therefore useful for separating price effects from real activity.
4. Retail versus wholesale
Retail and wholesale activities differ in the stage of distribution and customer relationship. Statistical classifications help separate these activities consistently.
5. Business surveys and administrative data
Surveys can collect detailed business characteristics, while tax or registration records may provide administrative information. Integration requires common identifiers and concepts.
6. Exam approach
Identify whether the question asks for a stock, flow, value, volume, rate or ratio. Then state the business population and reference period.
Turnover
Monetary value of sales or business activity over a defined period.
Volume
Quantity or real activity measure separated conceptually from price.
Establishment
A defined business statistical unit used under a specified framework.
ISS Exam Focus
For official-statistics questions, always define the statistical unit, reference period, coverage, numerator and denominator. Distinguish counts, rates, ratios, stocks and flows before interpreting a number.
Exam tip
In numerical questions, write the formula first, substitute values second and finish with the correct unit. In descriptive questions, structure the answer around definition, methodology, data source, quality and interpretation.
Three important questions on this topic
Try each one on your own first, then tap the answer.
Why is turnover not a direct measure of physical sales volume?
Show answer
Because turnover is monetary and can change due to both prices and quantities.
Retail turnover rises from ₹80 crore to ₹92 crore. Calculate the growth rate.
Show answer
Growth = 12/80 × 100 = 15%.
Explain why trade statistics need both value and volume measures.
Show answer
Discuss price effects, quantity changes, deflation or volume measurement, classification, business coverage and the importance of consistent reference periods.
Key takeaways
- Definitions and statistical units determine what an official statistic actually measures.
- Coverage, reference period and denominator are essential for meaningful comparison.
- Administrative records, surveys and census-type operations have different strengths and limitations.
- Always separate a statistical observation from an explanation or causal interpretation.
