Other Household Survey [hh/oth]
The 2012/2013 Tanzania National Panel Survey (NPS) is the third round in a series of nationally representative household panel surveys that collect information on a wide range of topics including agricultural production, non-farm income generating activities, consumption expenditures, and a wealth of other socio-economic characteristics. All three rounds of the NPS have been implemented by the Tanzania National Bureau of Statistics (NBS).
The first round of the survey was conducted over twelve months, from October 2008 to September 2009. The main fieldwork of the second round of the NPS started in October 2010 and finished in September 2011, with specialized tracking teams remaining in the field until November 2011. Similarly, the duration and timing of the field work for the third round of NPS was from October 2012 to November 2013.
The main objective of the NPS is to provide high-quality household-level data to the Tanzanian government and other stakeholders for monitoring poverty dynamics, tracking the progress of the MKUKUTA II poverty reduction strategy1, and to evaluate the impact of other major, national-level government policy initiatives.
As an integrated survey covering a number of different socioeconomic factors, it compliments other more narrowly focused survey efforts, such as the Demographic and Health Survey on health, the Integrated Labour Force Survey on labour markets, the Household Budget Survey on expenditure, and the National Sample Census of Agriculture.
Secondly, as a panel household survey in which the same households are revisited over time, the NPS allows for the study of poverty and welfare transitions and the determinants of living standard changes.

Sampling
The original sample size of 3,265 households was designed to be representative at the national, urban/rural, and major agro-ecological zones. The total sample size of 3,265 households is clustered in 409 Enumeration Areas (2,063 households in rural areas and 1,202 urban areas) across Tanzania and Zanzibar. The NPS sample allows analysis at 4 primary domains of inference, namely: Dar es Salaam, other urban areas on mainland Tanzania, rural mainland Tanzania, and Zanzibar.
The eligibility requirement for the National Panel Survey is defined as any household member aged 15 years and above, excluding live-in servants. Households with at least one eligible member where completely interviewed, including any subsequent non-eligible members present in the household. Any household or eligible members that had either moved or split away from a primary household were tracked and interviewed in their new location.
The resulting sample size for the third round of National Panel Survey, including National Panel Survey 2008/2009 and National Panel Survey 2010/2011 households plus new, or split-off, households in NPS 2012/2013, is 5,015 households.
No deviation. The sample was covered

The expansion factors for the NPS 2012/2013, variable "y3_weight", has been integrated into Section A, "HH_SEC_A" of the household dataset. Additionally, unique identifiers for the first-stage sampling units, "clusterid", and for the sampling strata, "strataid" can also be located in Section A of the household dataset.
The methodology used to calculate the panel weights for the NPS 2012/2013 was developed as part of the LSMS-ISA work program. Details on the methodology can be found in the paper: Himelein, Kristen. 2013. "Weight Calculations for Panel Surveys with Subsampling and Split-off Tracking." Statistics and Public Policy, vol(1), pp40-45.
Survey instrument
The third round of the National Panel Survey consists of four Questionnares: a Household Questionnaire, Agriculture Questionnaire, Livestock/Fishery Questionnaire, and a Community Questionnaire.
The Household Questionnaire is comprised of thematic sections.
Agriculture Questionnares collected information at both the plot and crop level on inputs, production and sales, consistent with key phases in the agricultural value chain.
The Livestock / Fisheries Questionnaire is administered to all households participating in these activities and asks about the inputs, outputs, labour, and sales related to these activities.
The Community Questionnaire collects information on physical and economic infrastructure and events in surveyed communities.

The survey was primarily implemented by seven mobile field teams, each composed of: one supervisor, five or six enumerators, one data entry technician, and one driver. In addition, there were also two dedicated mobile tracking teams that were each composed of: one supervisor, two enumerators, one data entry technician and one driver.
For the third round, households from the second round were grouped into clusters. These third round clusters are very similar to the enumeration areas from the second round in that they both consist of primarily the same households. However, each cluster also included both distance and local tracking cases from the second round that reside nearby but not in the same exact enumeration area as the other households in that cluster. Efforts were made in the groupings to maintain the timing of the previous rounds survey.
Field teams visited each cluster for between 4-5 days. The questionnaires were administered to the selected households over the course of that time. This allowed the field team to make return visits to the household to complete the entire Household questionnaire, Agriculture questionnaire for farming households, and Livestock/Fisheries questionnaire for households engaged in livestock or fisheries activities.
To ensure the depth and quality of each section of the survey, the questionnaire was administered across multiple respondents to the most knowledgeable about each topic. For all of the sampled households, areas of all owned and/or cultivated agricultural plots were measured via GPS unless the household refused, the terrain was too difficult, or if the plot was more than 1 hour from the location of the household. Anthropometric measurements were taken for all individuals that were at home, not too ill, and willing to participate.
The main data collection began in October 2012 and finished in October 2013, with tracking fieldwork continuing until the end of November 2013. The survey was primarily implemented by seven mobile field teams, each composed of: one supervisor, five or six enumerators, one data entry technician, and one driver.
In addition, there were also two dedicated mobile tracking teams that were each composed of: one supervisor, two enumerators, one data entry technician and one driver.
