2. Methodology
The paper will show the duplication of data problem and how to solve it
by generating the MEF. Because there are different frames of establishments
are overlapped and the same establishment exists in different frames in
addition to having more than one source of data. Therefore, CAPMAS seeks
unified sources of data to become the main source of data because it is the
national statistical office and deletes any duplication in data of establishments
and covers all activities (public sector – governmental sector – private/
investment sector); so the steps to achieve that with generating the MEF by
creating a unique code for each establishment. This can be done as follows:
Firstly; integrating the frames of the Egyptian economic census (8 frames)
which was made by sampling technique because plans for the 2013 Economic
Census were based on having a sample size of up to 180000 establishments,
in order to provide reliable results for as many four-digit ISIC activities as
possible with creating the comprehensive economic frame: using seven frames
to ensure a comprehensive coverage of all establishments in the private sector
as follows:

1. Area sample
The area sample design is used to cover small-sized establishment, the
area sampling frame of EAs that was used for the 2013 Economic Census was
based on the data and cartographic information and GIS from the 2006 Census
of Establishments and has been selected in two stages:

a. The first stage
- Selecting a sample size of 1,800 counting area (EA) from the 2006
census facilities to be allocated proportionally among the
governments according to any number of small establishment in
each government taking into account the division of government
to urban and rural areas. After that, the sample of small
governments is increased with a minimum of 40 counting area and
decreasing the sample of big governments. Next, the selection
process is done with probability proportional to size (PPS) taking
into account the relative importance of economic activity as a
measure of the size of the counting area. The field implementation
in selected regions of the sample is necessary to prepare a list of
all of the establishments in the area in 1800 (sample areas as well
as to determine the geographic information and data of economic
activity and the number of employment) for each establishment.
- After the completion of the field work and the collected data have
been electronically recorded, and after the completion of the full
process, a sample of second stage is selected.
