Other Household Survey [hh/oth]
Niger is part of the Living Standards Measurement Study - Integrated Surveys on Agriculture (LSMS-ISA) program.
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 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, only the household and agriculture/livestock questionnaires are administered.

Sampling
The ECVM/A 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. 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) will be 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 will be selected with equal probability in each urban or rural ZD respectively. The base for the sample will be 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.
Survey instrument
The household questionnaire comprises 13 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. The second visit household questionnaire is a reduced version of the version used in the first round. It includes information to determine if members who were in the household in the first visit are still in the household and if there are any new members. When there are new members, the questionnaire is used to collect basic information on their socio-demographic.
Like the household questionnaire, the agriculture/livestock questionnaire is divided into sections and sub-sections. The different sections, numbering 8 in all, address the issues of access to land, rainy season agriculture, "contre-saison" agriculture (dry season), livestock, forestry, agricultural equipment, access to agricultural extension services, and climate change. The agriculture and livestock questionnaire, second visit, collects information on harvests from the recently completed season and information on livestock rearing and production. In addition, information was collected on tree crops, agricultural extension, and climate change.
The community questionnaire has 7 sections. In addition, the cover pages collects general information (identification information, etc.) and section 0 provides the names of the respondents. In the second visit, the community questionnaire was used only to collect local prices.
Data collection
| Start | End | Cycle |
|---|---|---|
| 2011-07-18 | 2011-09-17 | First visit |
| 2011-11-03 | 2012-01-02 | Second visit |
First visit: Data collection was organized in teams. A team was composed of a supervisor, three enumerators, and one data entry operator. Each team was accompanied by a driver. The enumerator visited one household per day. During the first visit, each enumerator visited approximately 84 households using a cycle of 3 days in urban areas and 4 days in rural areas. After the teams collected data from three ZDs, they had a day of rest. Data collection was done between 18 July and 17 September 2011. In total, there were 48 enumerators, 16 data entry operators, 16 supervisors and 16 drivers divided in 16 teams.
Second visit: As with the first visit, the work to collect the data was done in teams. A team was composed of a supervisor, three enumerators, and one data entry operator. Each team was accompanied by a driver. The enumerators completed one household per day. The enumerators did 84 households during the visit in a cycle of 3 days in urban areas and 4 days in rural areas. After the teams collected data from three ZDs, they had a day of rest. The data collection period went from 3 November 2011 to 2 January 2012. In total, there were 48 enumerators, 16 data entry operators, 16 supervisors and 16 drivers divided in 16 teams.
The first visit used three questionnaires to collect data. The household questionnaire collected information at the individual level (demographics, education, health, and employment) and information at the household level (housing, durable goods, transfers, shocks, etc). The agriculture questionnaire collected information about the post-planting period (plots, crops, inputs, labor, etc). The community questionnaire collected information about characteristics of the community in which the households selected for the survey were found.
The second visit also used three questionnaires to collect data. These questionnaires were similar to those used in the first passage. Because the households visited in the first round were re-visited, the household questionnaire collected information at the individual level (demographics, education, health, and employment) only for those people who joined the household after the implementation of the first visit or for people who were in the household in the first visit, but who had not been interviewed. Some information that had been collected at the household level in the first visit - household enterprises, housing characteristics, durable goods, non-wage revenues, transfers and shocks - was not collected again in the second visit. Complete information was collected on non-food expenditures and food consumption. The agriculture questionnaire collected information about the post-harvest period (plots, crops, outputs, labor, etc) and livestock. While the community questionnaire in its entirety was not administered, the price data collection was done. The challenge for the second visit was to find the same households again. There is a large amount of migration during the year in order to find water and pasturage for livestock. The survey dates were designed so that the interviews were to be done during the period when households are in their home base, but between the two visits, 77 households could not be found.
Data processing
The data entry was done in the field simultaneously with the data collection. Each data collection team included a data entry operator who key 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.
