1 Module B-3 Designing and ICT Business Survey TRAINING COURSE ON THE PRODUCTION OF STATISTICS ON THE INFORMATION ECONOMY Unctad Manual Chapter 7

2 Module B3: Designing an ICT business survey UNCTAD 2 After completing this module you will be able to: Design a survey on ICT use in business (sample design) Build a questionnaire using internationally agreed indicators Decide on interviewing method Define outcome indicators Objectives Contents of this module B3.1. Survey design Coverage, target population, statistical units Use of statistical frames Stratification criteria Sample size and sample selection methods B3.2. Model questions and questionnaires Questions for a module on ICT Questionnaires for stand-alone surveys

3 Module B3: Designing an ICT business survey UNCTAD 3 Coverage, target population and statistical units As with other business surveys, the scope and target population of the ICT use surveys are defined in terms of: 1.Industry (economic activity) 2.Business size 3.Geographical location (sometimes) B3.1. Survey design Remember: The target population is the group of statistical units that are of interest The scope is the conceptual definition of the target population, the set of attributes that seize the target population Page 69

4 Module B3: Designing an ICT business survey UNCTAD 4 Industry scope The Partnership recommends: The core industries: The OECD core industries (ISIC Rev 3.1 D, F, G, H, I, K) The non core industries: ISIC rev 3.1 section J and division 92. In developing economies: The scope of ICT business surveys may deviate from the OECD recommendation to better suit country requirements. Partnership also encourages a broader scope, beyond OECD core and non-core industries. B3.1. Survey design Page 70

5 Module B3: Designing an ICT business survey UNCTAD 5 Business size A common scope criterion is business size based on number of employees. Partnership recommends a minimum size scope of 10 or more employees for international comparability. Some developing economies may decide to include microenterprises (<10 employees) if they represent a large share of the in-scope population. B3.1. Survey design Page 71

6 Module B3: Designing an ICT business survey UNCTAD 6 Geographical location The geographic scope of the business sector (and its parts) should in principle include the entire territory of the country. Include both urban and rural areas. It is necessary to establish a definition or urban/rural at country level. No international harmonized definition exist yet. B3.1. Survey design Page 77

7 Module B3: Designing an ICT business survey UNCTAD 7 Statistical units The Partnership recommends the “enterprise” as the statistical unit. It is the most common. The SNA93 concept of enterprise: “An institutional unit in its capacity as a producer of goods and services” With autonomy in decision-making One or more legal units involved in one or more activities at one or more locations A corporation or an unincorporated enterprise. B3.1. Survey design Page 75

8 Module B3: Designing an ICT business survey UNCTAD 8 Use of population statistical frames Business registers should be improved through the coordination with other sources General administrative registers: taxes, registrations, licenses, social security, etc. Specific registers: licenses for operating telecommunications businesses Statistical databases: updated from economic censuses. B3.1. Survey design

9 Module B3: Designing an ICT business survey UNCTAD 9 If no business register is available Population frames can be obtained from other sources Lists of live units in economic censuses External directories oCommercial telephone listings oIndustry association lists The frame should be checked in terms of coverage oComparison with external sources oAdjusting of the estimates (reweighting) If the population frame lacks information on industry or size oThe survey should include questions to classify the respondent unit B3.1. Survey design

10 Module B3: Designing an ICT business survey UNCTAD 10 Sample Design Sample selection should be made using probabilistic techniques This guarantees that the sample is truly representative of the population Only probabilistic (random) sampling allows calculation of estimates of the sampling error The design of a random sample should consider: The structure of the population of businesses (its stratification), The cost of collecting data and, The maximum acceptable statistical error associated with estimates. B3.1. Survey design

11 Module B3: Designing an ICT business survey UNCTAD 11 Stratification criteria Optimal stratification for ICT use business surveys Basic stratification variables oIndustry and oSize of business Additional stratification variable oGeographical location of the business B3.1. Survey design Page 77

12 Module B3: Designing an ICT business survey UNCTAD 12 Sample size Methods for deriving the sample size and design: Bottom-up procedure Use of estimates of sampling error and auxiliary information Setting the required precision (CV); no international recommendations Eurostat recommendations (page 78, number 208) Adjusting of total sample size Top-down Procedure Calculation of the overall sample size Available budget and collection unit cost Allocation of the sample by strata B3.1. Survey design

13 Module B3: Designing an ICT business survey UNCTAD 13 Sample Selection Methods Simple random samplingSimple random sampling Random draw of n numbers between 1 and N Generation of random numbers Statistical software Random numbers tables B3.1. Survey design

14 Module B3: Designing an ICT business survey UNCTAD 14 Sample Selection Methods Systematic samplingSystematic sampling Procedure Arrangement of units from 1 to N Obtain: - Interval K=N/n - Starting point t (random number between 1 and K) Selection of units t+i*k (i=0,1,...,n) Advantage: it may improve representativeness of the sample Disadvantage: it produces biased estimates (unless the weighting factor is adjusted) B3.1. Survey design

15 Module B3: Designing an ICT business survey UNCTAD 15 Topics covered by Sub-module B3.2 Building a questionnaire using internationally agreed indicators Selecting topics to be included in the questionnaire Preparing topic-related questions Choosing appropriate wording Preparing answer patterns Deciding on interviewing method Defining outcome indicators B3.2. Model questions and questionnaires
