Implementation Report for Afghanistan 2014 updated on 3 February 2014. 3.
Three levels of stratification were used in this country: industry, establishment size, and region. The original sample design with specific information of the industries
and regions chosen is described in Appendix C. 4.
Industry stratification was designed in the way that follows: the universe was stratified into manufacturing, retailwholesale, construction, and other
services. 5.
Size stratification was defined following the standardized definition for the rollout: small 5 to 19 employees, medium 20 to 99 employees, and large more than
99 employees. For stratification purposes, the number of employees was defined on the basis of reported permanent full-time workers.
6.
Regional stratification was defined in 5 regions Kabul, Hirat, Kandahar, Mazar, Jalalabad which include both city and the surrounding business areas.
III. Sampling implementation
7.
Given the stratified design, a sample frame containing a complete and updated list of establishments as well as information on all stratification variables number of
employees, industry, and region is required to draw the sample.
Great efforts were made to obtain the best source for these listings
. The quality of the sample frame was not optimal due to its being slightly out of date and due to the fact that individuals register their
“business” for visa purposes but in fact do not have a business at all.
8. Nielsen India Pvt. Ltd. was hired to implement the Afghanistan 2014 Enterprise
Survey. The team comprised of seven supervisors and sixteen interviewers. 9.
The sample frame used in Afghanistan was combined from 3 sources. The list of manufacturing firms was obtained from the Afghanistan Investment Support Agency AISA
and was updated in April 2012. The list for retail firms was generated by the implementing contractor for the 5 cities of fieldwork. The constructionother services list was obtained
from the implementing contractor and is largely based on firms registered with AISA. The records obtained from AISA contained the following information
- Business name; - Business address;
- Business sector classification code; - Total numbers of male and female employees;
- President and Vice President;
- Phone number and sometimes FAXemail address.
Counts from sample frame are shown below.

10. The sample frame, consisting of mostly AISA-register businesses, was used for
the selection of a sample with the aim of achieving 360 interviews with establishments of five or more employees.
11.
The quality of the frame was assessed at the onset of the project through visits to a random subset of firms and local contractor knowledge. The sample frame was not
immune from the typical problems found in establishment surveys: positive rates of non- eligibility, repetition, non-existent units, etc.
12.
Given the impact that non-eligible units included in the sample universe may have on the results, adjustments may be needed when computing the appropriate weights for
individual observations. Breaking down by stratified industries, the following sample targets were achieved using a4a and a6a:
