Main Objective of the Sample
Measure the Information and Communication Technology (ICT) usage by the employees of private enterprises in the Egyptian community.
Frame
It has been acquired from the census of enterprises for the year 2006.
Sample Design
Stratified sample, where the sampling unit measurement in the enterprise is determined according to the definition used by CAPMAS.
Stages for Drawing the Sample
1. Sample Size Criteria:
According to international organizations recommendations and international comparison requirements, it is preferred to focus on small, medium and large enterprises that have more than 9 employees when measuring ICT usages, which entails not focusing on the micro enterprises in the sample.
Hence, the sample consists of 80% (small, medium and large enterprises) whose employees exceed 9 employees and 20% (micro enterprises) whose employees are less than 9 employees. Micro enterprises were included in the sample because they employ a large portion of the employees included in the frame; therefore, they were not excluded from the sample.
Therefore, there are four strata:
1. Micro enterprises in urban areas.
2. Micro enterprises in rural areas.
3. Small, medium and large enterprises in urban areas.
4. Small, medium and large enterprises in rural areas.
To determine the number of enterprises included in each of the above mentioned strata, relative weights are used representing the relative importance of each of those strata in the frame or the population from which the sample is drawn, based on the number of included enterprises.
2. Economic Activity Criteria
Economic activities inside each stratum are distributed according to its normal distribution inside of each stratum in the frame. So if the activities in the micro enterprises in urban areas are distributed as follows: 40% manufacturing, 20% trade, 10% finance and insurance, then these weights will be used for micro enterprises in urban areas. Those weights will differ from a stratum to another according to the relative importance of activities inside each stratum, as explained in the frame.
Note: the sampling error should not exceed +/- 1.5 %.
