Core Welfare Indicators Questionnaire [hh/cwiq]
Series Information
The Government of Sierra Leone is committed to the system of tracking and measuring poverty reduction strategy (PRS). Statistics Sierra Leone (SSL) has the task of providing information for the management of Sierra Leone economy and society. CWIQ survey was one of the instruments adopted by SSL for assessing and monitoring welfare and poverty by proving indicators on poverty.
The CWIQ Survey covered all four Sierra Leone administrative regions and nineteen Local Councils. Five hundred twenty (520) Enumeration Areas (E.A.s) covering rural and urban areas in each of the Local Councils were sampled. Fifteen households were sampled in each EA and resulted in an overall sample of 7,800 households.

Abstract
The Core Welfare Indicators Questionnaire (CWIQ) is an instrument designed to collect minimum information not only for providing basic indicators for monitoring poverty alleviation programs, but more specifically for providing indicators for monitoring welfare and other social trends for the different sub-population groups across the country including provision of rapid information for programmes and policy decisions. This survey was designed to provide timely and reliable information on key economic and social indicators that underpins the planning, monitoring and revision of Government of Sierra Leone programmes, if the PRSP targets and goals are to be achieved.
The overall objective for conducting the CWIQ survey in Sierra Leone was to provide timely information for monitoring the implementation of the Sierra Leone Poverty Reduction Strategy and to begin a process of capacity building for the design, implementation, processing and analysis of household surveys within SSL to strengthen the Poverty Reduction Strategy Monitoring and Evaluation System.
The specific objectives included:
- Elaborating main indicators for social welfare and basic needs of the socioeconomic groups of the population;
- Identifying target groups for benefiting special action programmes designed by decision makers to address their needs;
- Monitoring changes happening in the households’ welfare overtime;
- Providing a database for social research;
- Elaborating on numerous sector programmes aimed at improving the welfare of the population across the country;
- Building models to stimulate the global impact of policy choices and the distribution of this impact.

Sampling
Sampling Procedure
The 2007 CWIQ Survey was carried out on a nationally representative sample of 7,800 households located in 520 E.A.s/Clusters. The survey was based on a stratified two stage sampling design using existing SSL sample frame (2004 Population and Housing Census). E.A.s were selected from each Local Council (LC). It should be stated that some of these LCs are rural areas while some are urban areas. In each LC, the first stage of sampling was a selection of E.A.s. The number of EAs selected in each LC was determined proportionately using the square root of the household population of the LC and that of the locality (Urban, Rural).
At the second stage of sampling, 15 households were selected for each EA for inclusion in the sample. The selection in each cluster included additional households, as substitutes, to take into account e.g. households that may have moved between the time of listing and the date of enumeration. Below is the distribution of total number of EAs, sampled EAs and total number of households in each LC.

Response Rate
A total of 7,797 households were successfully enumerated from a sample of 7,800 households giving the survey coverage rate of 99.96 percent. Three households could not be located at the time of data processing.

Supervision
Field quality control measures were established at two levels. The first level was the supervisors work at the data collection stage. The second level of quality control was the monitoring of field work by senior managers from SSL head office.
Data Collection Notes
Training for Fieldwork
Training for fieldwork was conducted at two levels. The first level of training was a 5-day CWIQ Pilot Survey Interviewer training program which was undertaken at SSL head office from 19 to 23 February 2007. This training included twenty six (26) trainees that were selected among SSL staff. The plan was to train 20 of them as Interviewers for the Pilot Survey and appoint them as Supervisors for the Main Survey. In addition it was planned that they should assist in the training of Interviewers for the Main survey. This training was therefore viewed as training of trainers for the CWIQ main survey. Also included in the training program was 6 SSL Data Processing staff that were selected to participate in the verification and data processing of the CWIQ Pilot and Main Survey data. It was considered important for them to participate so that they could be trained on the tasks they were expected to perform. Therefore, a total of 26 SSL staff were trained for the CWIQ Pilot survey.

Questionnaires
Questionnaires
The Generic scannable CWIQ questionnaire supplied by the World Bank was modified and used for the CWIQ Pilot survey. The CWIQ Pilot survey questionnaire was further modified on the basis of experience during the pilot survey conducted just before the main survey. This modified questionnaire was used as the main data collection instrument and contains pre-coded multiple-choice responses. The questionnaire is divided into modules covering subject areas including interview information, list of household members, education, health, employment, household assets, household amenities, poverty predictors, children under five, maternal child health and agriculture.
Data Processing
Data Editing
Data processing was organized to run concurrently with the fieldwork and commenced a week after the commencement of the fieldwork. The CWIQ data processing system resembled a typical survey data processing system with three main stages: data entry, validation and tabulation. Unique features if CWIQ data processing included use of optical scanners, eliminating the need for manually keying data; the system used a relational database management system (Microsoft Access) to store the survey data instead of text or proprietary file formats; The system was programmed in a general purpose programming language (Microsoft Visual Basic for Applications) instead of a generalized survey data processing package. The data processing procedure involved: Reception of questionnaire; Data preparation; Scanning and evaluation; Verification and committing; Conversion of data; and Validation of data.
