The GHS - Panel will be conducted every two years.\n\nThis first wave consists of two visits to the household: the post-planting visit (August - October 2010) occurred directly after the planting season to collect detailed information on household characteristics including preparation of plots, inputs used, labour used for planting and other issues related to the planting season.  The post-harvest visit (Feburary-April 2011) occurred after the harvest season and collected additional information on household characteristics along with information on crops harvested, labour used for cultivating and harvest activities, and other issues related to the harvest cycle.  \n\nThe survey is the result of a partnership that NBS has established with the Federal Ministry of Agriculture and Rural Development (FMA&RD), the National Food Reserve Agency (NFRA), the Bill and Melinda Gates Foundation (BMGF) and the World Bank (WB)."},"study_info":{"topics":[{"topic":"consumption\/consumer behaviour","vocab":"","uri":""},{"topic":"economic conditions and indicators","vocab":"","uri":""},{"topic":"income, property and investment\/saving","vocab":"","uri":""},{"topic":"agricultural, forestry and rural industry","vocab":"","uri":""},{"topic":"employment","vocab":"","uri":""},{"topic":"unemployment","vocab":"","uri":""},{"topic":"working conditions","vocab":"","uri":""},{"topic":"compulsory and pre-school education","vocab":"","uri":""},{"topic":"vocational education","vocab":"","uri":""},{"topic":"housing","vocab":"","uri":""},{"topic":"children","vocab":"","uri":""},{"topic":"gender and gender roles","vocab":"","uri":""},{"topic":"religion and values","vocab":"","uri":""},{"topic":"health policy","vocab":"","uri":""},{"topic":"plant and animal distribution","vocab":"","uri":""},{"topic":"transport, travel and mobility","vocab":"","uri":""},{"topic":"basic skills education","vocab":"","uri":""},{"topic":"post-compulsory education","vocab":"","uri":""},{"topic":"information society","vocab":"","uri":""},{"topic":"accidents and injuries","vocab":"","uri":""},{"topic":"general health","vocab":"","uri":""},{"topic":"health care and medical treatment","vocab":"","uri":""},{"topic":"nutrition","vocab":"","uri":""},{"topic":"migration","vocab":"","uri":""},{"topic":"specific social services: use and provision","vocab":"","uri":""},{"topic":"information technology","vocab":"","uri":""}],"abstract":"Towards the goal of improving agricultural statistics, the World Bank, through funding from the Bill and Melinda Gates Foundation (BMGF), is supporting seven countries in Sub-Saharan Africa in strengthening the production of household-level data on agriculture. \n\nThe General Household Survey (GHS), is a cross-sectional survey of 22,000 households is carried out annually throughout the country.  Under the work of the partnership, a full revision of the questionnaire was undertaken and, at the same time, a sub-sample of the GHS now forms a panel survey. The panel component (GHS-Panel) applies to 5,000 households of the GHS collecting additional data on multiple agricultural activities and household consumption.  As the focus of this panel component is to improve data from the agriculture sector and link this to other facets of household behavior and characteristics the GHS-Panel drew heavily on the Harmonized National Living Standards Survey (HNLSS - a multi-topic household survey) and the National Agricultural Sample Survey (NASS - the key agricultural survey) to create a new survey instrument to shed light on the role of agriculture in households' economic wellbeing that can be monitored over time.\n\nThe first wave of the revised GHS and GHS-Panel was carried out in two visits to the panel households (post-planting visit in August-October 2010 and post-harvest visit in February-April 2011) and one visit to the full cross-section (in parallel with the post-harvest visit to the panel). The GHS panel will be carried out every two years while the GHS-cross section is usually carried out annually.","coll_dates":[{"start":"2011-02-10","end":"2011-04-15","cycle":"eight weeks"}],"nation":[{"name":"Nigeria","abbreviation":"NGA"}],"geog_coverage":"National Coverage Local Government Sector (Urban\/Rural)","analysis_unit":"Households","universe":"Household","data_kind":"Sample survey data [ssd]","notes":"The survey covered a wide range of socio-economic topics which are highlighted  two different questionnaires administered to the household.

The sample size of the panel, General Household Survey (GHS), is not adequate for state-level estimates, unlike the full GHS.  \n\nThe sample was derived using a 2-stage sampling method. In the first stage, Enumeration Areas (EAs) were selected as  Primary Sampling Units (PSUs). Selection was based on probability proportional to size (PPS) of the total EAs in each state and FCT, Abuja and the total households listed in those EAs. A total of 500 EAs were selected using this method. In the second stage, households were selected randomly using the systematic selection of ten (10) households per EA. This involved obtaining the total number of households listed in a particular EA, and then calculating a Sampling Interval (S.I) by dividing the total households listed by ten (10).  The next step was to generate a random start 'r' from the table of random numbers which stands as the 1st selection. Consecutive selection of households was obtained by adding the sampling interval to the random start.   \n\nDetermination of the sample size at the household level was based on the experience gained from previous rounds of the GHS, in which 10 households per EA are usually selected and give robust estimates.  \n\nIn all, 500 clusters\/EAs were canvassed and 5,000 households were interviewed. These samples were proportionally selected in the states such that different states had different samples sizes.  The distribution of the samples are shown in Table 3.1 below which shows the size of the sample in each state, by geopolitical zone and urban\/rural break-out. \n\nHouseholds were not selected using replacement. Thus the final number of household interviewed was slightly less than the 5,000 eligible for interviewing.  The final number of households interviewed was 4,986 for a non-response rate of 0.3 percent.  A total of 27,533 household members were interviewed.  In the second, or Post Harvest Visit, some household had moved as had individuals, thus the final number of households with data in both points of time (post planting and post harvest) is 4,851, with 27,993 household members.","coll_mode":"Face-to-face paper [f2f]","weight":"Population weight was calculated for the panel household.  This weight variable (WGHT) has been included in household dataset: Section A (SECTA).  When applied, this weight will raised the sample households and individuals to national values.\n\nFor any analysis, the SECTA data set will need to be merged with the file that is to be used.","cleaning_operations":"The data cleaning process was done in a number of stages.  The first step was to ensure proper quality control during the fieldwork.  This was achieved in part by using the concurrent data entry system designed to highlight many of the errors that occurred during the fieldwork.  Errors that are caught at the fieldwork stage are corrected based on re-visits to the household on the instruction of the supervisor.  The data that had gone through this first stage of cleaning was then sent from the state to the head office of NBS where a second stage of data cleaning was undertaken.  \n\nDuring the second stage the data were examined for out of range values and outliers.  The data were also examined for missing information for required variables, sections, questionnaires and EAs.  Any problems found were then reported back to the state where the correction was then made.  This was an ongoing process until all data were delivered to the head office.  \n\nAfter all the data were received by the head office, there was an overall review of the data to identify outliers and other errors on the complete set of data.  Where problems were identified, this was reported to the state.  There the questionnaires were checked and where necessary the relevant households were revisited and a report sent back to the head office with the corrections.\n\nThe final stage of the cleaning process was to ensure that the household- and individual-level data sets were correctly merged across all sections of the household questionnaire.  Special care was taken to see that the households included in the data matched with the selected sample and where there were differences these were properly assessed and documented.  The agriculture data were also checked to ensure that the plots identified in the main sections merged with the plot information identified in the other sections.  This was also done for crop-by-plot information as well."},"analysis_info":{"response_rate":"The response rate was 99.9% including replacement at household level.
