To date this is the most detailed Agricultural Census carried out in Africa. The census was carried out in order to:\n\n\u00b7 Identify structural changes if any, in the size of farm household holdings, crop and livestock production, farm input and implement use. It also seeks to determine if there are any improvements in rural infrastructure and in the level of agriculture household living conditions;\n\u00b7 Provide benchmark data on productivity, production and agricultural practices in relation to policies and interventions promoted by the Ministry of Agriculture and Food Security and other stake holders.\n\u00b7 Establish baseline data for the measurement of the impact of high level objectives of the Agriculture Sector Development Programme (ASDP), National Strategy for Growth and Reduction of Poverty (NSGRP) and other rural development programs and projects.\n\u00b7 Obtain benchmark data that will be used to address specific issues such as: food security, rural poverty, gender, agro-processing, marketing, service delivery, etc.","coll_dates":[{"start":"2004-01-15","end":"2004-03-15","cycle":""}],"nation":[{"name":"United Republic of Tanzania","abbreviation":"TZA"}],"geog_coverage":"National Coverage","analysis_unit":"Households","universe":"Small scale and  Large Scale Farmers within the community.","data_kind":"Sample survey data [ssd]","notes":"The census covered agriculture in detail as well as many other aspects of rural development and was conducted using three different questionnaires:\n\u00b7Small scale farm questionnaire \n\u00b7Community level questionnaire\n\u00b7Large scale farm questionnaire"},"method":{"data_collection":{"time_method":"2002\/03 agricultural year.","sampling_procedure":"The Mainland sample consisted of 3,221 villages.

In Zanzibar a total of 317 Enumeration Areas (EAs) were selected and 4,755 agriculture households were covered.  Nationwide, all regions and districts were sampled except three urban district (two from Mainland and one from Zanzibar). \nIn both Mainland and Zanzibar, a stratified two stage sample was used. The number of villages\/Enumeration Areas (EAs) were selected for the first stage with a probability proportional to the number of villages in each district.
