municipal level

Abstract

This is a study on SBS-Survey, one of the main surveys of the national statistical program of

Albania. The main objective of it is to suggest improvements on the sample design of SBS with

the aim to use it on level of municipalities. The hypotheses included in this study are based on

empirical analysis, where the information used is limited, compared to the traditional method

used in the business structural survey. Suggestions for alternative, indirect methods are well

provided and are suggested to be used on the future.

Introduction

Dierent methods can be used for SBS sampling techniques despite the diculties

we may encounter due to the lack of auxiliary information, in order to ensure a

good sample allocation and to guarantee accuracy in municipal level according to

the new administrative division. Although being practical and objective, indirect

methods are not always very accurate. Among them, probably the combination of

the current method, by adding in stratication the municipal level, and, on the other

hand, considering the number of employees taken from business register (instead of

turnover estimates from previous year) can give us an identication of the economic

situation at the municipal level, which nevertheless remains to be seen.

Whichever method chosen to study structural business data at municipal level, it

will always reveal dierent levels of accuracy and precision, as well as dierent cost–

benet ratios and advantages and disadvantaged.

A good choice of a survey method requires clear research objectives and the awareness

about the method eciency and limitations towards the desired objectives. Limitations

may vary as much as from operational conditions (lack of human recourses, longer

time for eld work management, time added for data cleaning), such as accessibility

to the area or the interaction with local people (in the respective municipalities), to

the project execution timing, or the available budget.

In this sense, this study aimed at investigating the strengths and weaknesses of these

three methods; (1) Detailing further the actual stratum by adding the municipal level

(with a grouping of micro enterprises 1-4 employees) and the required accuracy at

the publication domain (according to the method applied so far in SBS), (2) detailing

the stratum as in case one, but the required accuracy for this case is at the municipal

level, (3) detailing the stratum as in case (1) and (2), but the required accuracy for this

case is at the municipal level and publication domains according to current SBS.
