Micro-Enterprise Survey 2006 - Angola

Abstract
---------------------------

This research of private non-agricultural firms with less than five employees was conducted in Angola between June and July 2006, at the same time with 2006 Angola Enterprise Survey. Data from 115 establishments were analyzed.

Micro-Enterprise Survey topics include firm characteristics, gender participation, access to finance, annual sales, costs of inputs/labor, workforce composition, bribery, licensing, infrastructure, trade, crime, competition, capacity utilization, land and permits, taxation, informality, business-government relations, innovation and technology, and performance measures. The questionnaire also assesses the respondents' opinions on what are the obstacles to firm growth and performance.

Geographic coverage

National

Analysis unit
---------------------------

The survey targets manufacturing/services sector establishments with one to four employees.

Universe
---------------------------

The whole population, or the universe, covered in the Enterprise Surveys is the non-agricultural economy. It comprises: all manufacturing sectors according to the ISIC Revision 3.1 group classification (group D), construction sector (group F), services sector (groups G and H), and transport, storage, and communications sector (group I). Note that this population definition excludes the following sectors: financial intermediation (group J), real estate and renting activities (group K, except sub-sector 72, IT, which was added to the population under study), and all public or utilities sectors.

Kind of data
---------------------------

Sample survey data [ssd]

Sampling procedure
---------------------------

Sampling techniques are similar for Angola Micro-Enterprise and Enterprise 2006 surveys.

In the Enterprise Survey, the universe is stratified by industry sectors, establishment size and regions. In the Micro-Enterprise Survey, stratification by size is missing: all businesses surveyed have less than five workers.

For more technical details on the sampling strategy for the Enterprise Surveys, please review "Sampling Methodology" in "Technical Documents" folder.

Mode of data collection
---------------------------

Face-to-face [f2f]

Research instrument
---------------------------

The current survey instrument is available:
Angola Micro-Enterprise Survey Questionnaire 2006.

Cleaning operations
---------------------------

Data entry and quality controls are implemented by the contractor and data is delivered to the World Bank in batches (typically 10%, 50% and 100%). These data deliveries are checked for logical consistency, out of range values, skip patterns, and duplicate entries. Problems are flagged by the World Bank and corrected by the implementing contractor through data checks, callbacks, and revisiting establishments.
