Abstract

The ECVMA is an integrated multi-topic household survey done for the purpose of evaluating poverty and living conditions in Niger. The main objectives of the ECVMA are to: - Gauge the progress made with achievement of the Millennium Development Goals (MDGs); - Facilitate the updating of the social indicators used in formulating the policies aimed at improving the living conditions of the population; - Provide data related to several areas that are important to Niger without conducting specific surveys on individual topics ; - Provide data on several important areas for Niger that are not necessarily collected in other more specific surveys.

The ECVMA involves two visits, which means that each household is visited twice. The first visit takes place during the planting season. The second visit takes place during the harvest season. The household and agriculture/livestock, as well as, the community/price questionnaire are administered during the first visit. During the second visit, only the household and agriculture/livestock questionnaires are administered.

Sampling procedure

The ECVMA 2011 has been designed to have national coverage, including both urban and rural areas in all the regions of the country. The domains are defined as the entire country, the city of Niamey; and other urban areas, rural areas, and in the rural areas, agricultural zones, agro-pastoral zones and pastoral zones. Taking this into account, 26 explicit sampling strata were selected: Niamey, and urban, agriculture, agro-pastoral and pastoral zones of the seven regions other than Niamey. The target population is drawn from households in all 8 regions of the country with the exception of certain strata found in Arlit (Agadez Region) because of difficulties in going there, the very low population density, and collective housing. The portion of the population excluded from the sample represents less than 0.4% of the total population of Niger. Out of a total of 36,000 people not included in the sample design, about 29,000 live in Arlit and 7,000 in collective housing. The sample was chosen through a random two stage process.

In the first stage a certain number of Enumeration Areas (known as Zones de Dénombrement or ZDs) were selected with Probability Proportional to Size (PPS) using the 2001 General Census of Population and Housing as the base for the sample, and the number of households as a measure of size. In the second stage, 12 or 18 households were selected with equal probability in each urban or rural ZD respectively. The base for the sample was an exhaustive listing of households that will be done before the start of the survey. The total estimated size of the sample is 4,074 households. The fact that this is the first survey with panel households to be revisited in the future was taken into account in the design and therefore it is possible to lose households between the two surveys with minimal adverse effects on the analyses.

Cleaning operations

The data entry was done in the field simultaneously with the data collection. Each data collection team included a data entry operator who entered the data soon after it was collected. The data entry program was designed in CSPro, a data entry package developed by the US Census Bureau. This program allows three types of data checks: (1) range checks; (2) intra-record checks to verify inconsistencies pertinent to the particular module of the questionnaire; and (3) inter-record checks to determine inconsistencies between the different modules of the questionnaire. The data entry from the first passage was completed in September 2011 and data cleaning was completed in December. The data cleaning process took longer than expected because it was done simultaneously with preparing for the second visit. Data entry from the second visit was completed in January 2012 and the data cleaning for both rounds was completed in August 2012.

Abstract

Niger is part of the Living Standards Measurement Study - Integrated Surveys on Agriculture (LSMS-ISA) program. This program has developed a household level survey with a view to enhancing our knowledge of agriculture in Sub-Saharan Africa, in particular, its role in poverty reduction and the techniques for promoting efficiency and innovation in this sector. To achieve this objective, an innovative model for agricultural data collection in this region will need to be developed and implemented. To this end, activities conducted in the future will be supported by four main pillars - a multisectoral framework, institutional integration, analytical capacity building, and active dissemination.

• First, agricultural statistical data collection must be part of an expanded and multisectoral framework that goes beyond the rural area. This will facilitate generation of the data needed to formulate effective agricultural policies throughout Niger and in the broader framework of the rural economy.

• Second, agricultural statistical data collection must be supported by a well-adapted institutional framework suited to fostering collaboration and the integration of data sources. By supporting a multi-pronged approach to data collection, this project seeks to foster intersectoral collaboration and overcome a number of the current institutional constraints.

• Third, national capacity building needs to be strengthened in order to enhance the reliability of the data produced and strengthen the link between the producers and users of data. This entails having the capacity to analyze data and to produce appropriate public data sets in a timely manner. The lack of analytical expertise in developing countries perpetuates weak demand for statistical data.

• Consequently, the foregoing has a negative impact on the quality and availability of policy-related analyses. Scant dissemination of statistics and available results has compounded this problem.

In all countries where the LSMS-ISA project will be executed, the process envisioned for data collection will be a national household survey, based on models of LSMS surveys to be conducted every three years for a panel of households. The sampling method to be adopted should ensure the quality of the data, taking into account the depth/complexity of the questionnaire and panel size, while ensuring that samples are representative.

The main objectives of the ECVM/A are to:

• Gauge the progress made with achievement of the Millennium Development Goals (MDGs);

• Facilitate the updating of the social indicators used in formulating the policies aimed at improving the living conditions of the population;

• Provide data related to several areas that are important to Niger without conducting specific surveys on individual topics ;

• Provide data on several important areas for Niger that are not necessarily collected in other more specific surveys.

Geographic coverage

The ECVM/A 2014 is a panel survey with the ECVM/A 2011. The ECVM/A 2011 was designed to have national coverage, including both urban and rural areas in all the regions of the country. The domains are defined as the entire country, the city of Niamey; and other urban areas, rural areas, and in the rural areas, agricultural zones, agro-pastoral zones and pastoral zones.

2011 Survey

The ECVM/A 2011 was been designed to have national coverage, including both urban and rural areas in all the regions of the country. The domains are defined as the entire country, the city of Niamey; and other urban areas, rural areas, and in the rural areas, agricultural zones, agro-pastoral zones and pastoral zones. Taking this into account, 26 explicit sampling strata were selected: Niamey, and urban, agriculture, agro-pastoral and pastoral zones of the seven regions other than Niamey. The target population was drawn from households in all 8 regions of the country with the exception of certain strata found in Arlit (Agadez Region) because of difficulties in going there, the very low population density, and collective housing. The portion of the population excluded from the sample represents less than 0.4% of the total population of Niger. Of a total of 36,000 people not included in the sample design, about 29,000 live in Arlit and 7,000 in collective housing.

The sample was chosen through a random two stage process:

• In the first stage a certain number of Enumeration Areas (known as Zones de Dénombrement or ZDs) was selected with Probability Proportional to Size (PPS) using the 2001 General Census of Population and Housing as the base for the sample, and the number of households as a measure of size.

• In the second stage, 12 or 18 households were selected with equal probability in each urban or rural ZD respectively. The base for the sample was an exhaustive listing of households that would be done before the start of the survey.

The total estimated size of the 2011 sample was 4,074 households. The fact that this was the first survey with panel households to be revisited in the future was taken into account in the design, making it possible to lose households between the two surveys with minimal adverse effects on the analyses.

2014 Survey

The ECVM/A 2014 is a panel survey with the ECVM/A 2011. All households are identified by three variables - GRAPPE, MENAGE and EXTENSION. GRAPPE is the cluster in which the household is located and MENAGE is the household number within that cluster. The GRAPPE and MENAGE identifiers of the households in 2014 are identical with the grappe and menage identifiers in 2011.

In the ECVM/A 2014, all households that had been interviewed in 2011 were tracked. Households that did not move were interviewed in their existing location. Households that had moved to other locations in Niger were followed and interviewed in their new locations if they could be found in the new location. Households that moved outside of Niger were not followed. Households are identified by the GRAPPE and MENAGE identifiers from 2011 even if they moved to a new location.

Individuals who moved from households, for example women who married and moved to their husband's household or men who moved out to form their own household, were also tracked. In the new location, the individual and all members in the new household were supposed to be interviewed. However in the final data set it is difficult to determine among the households of tracked individuals which one was in the original household and which are the new participants in the survey. While the GRAPPE and MENAGE are identical between the 2011 household and the movers from the 2014 survey, the individual identifiers within the household cannot be matched for these households.

Households that did not move are identified as code "0" in the variable EXTENSION. Households that moved as an entire household are identified as code "1" in variable EXTENSION. Households with an individual who moved from an original household and resided in a new household in 2014 are identified as code "2" in variable EXTENSION.

Within households, individuals should have the same identification numbers as they had in 2011. The variable MS01Q00 in the 2014 data contains the individual identification number within the household. In 2011, the variable is ms01q00. The identification numbers for members who left the household between 2011 and 2014 should not be found in the 2014 data. Their identification numbers should not have been reassigned to any other members. New members who joined the household after the 2011 survey will have identification numbers starting after the highest identification number found in the 2011 data. It is always possible that there were mistakes made in the identification of individuals in the households and the data may not be perfectly matched.

The households that moved maintain the GRAPPE (cluster) and MENAGE (household within the cluster) identification information from 2011 so that they can be matched back to information from the 2011 survey. They may have moved to a different region in the country, but are identified with their original location.

HOUSEHOLD QUESTIONNAIRES - FIRST VISIT

The ECVM/A involves two visits, which means that each household is visited twice. The first visit takes place during the planting season. The second visit takes place during the harvest season. The household and agriculture/livestock, as well as the community/price questionnaire are administered during the first visit. During the second visit, the household and agriculture/livestock questionnaires are administered in full, but the community questionnaire only collects price information.

The household questionnaire comprises 18 sections, not including the cover page which covers information of a general nature (identity, name of household head) and Section 0 which covers detailed information on household identification and the results of the survey. In the first visit, 16 of the sections were administered.

• Section 1 focuses on the socio-demographic characteristics of household members (gender, age, relations with household head, survival of relations);

• Sections 2 and 3 focus respectively on the education and health of household members;

• Section 4 focuses on the characteristics of the labor market and seeks to determine whether the subject is inactive (retirees, for example), unemployed or employed; and in the case of those in employment, to identify the characteristics of their employment (socio-professional category, seniority, working hours,
