Abstract
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 Five Year Development Plan (FYDP) II poverty reduction strategy1 and its predecessor plans, and evaluating 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 (DHS) on health, the Integrated Labour Force Survey (ILFS) on labour markets, the Household Budget Survey (HBS) on expenditure, and the National Sample Census of Agriculture (NSCA). 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
Sampling Procedure
The NPS sample was refreshed for NPS 2014/2015. a newly completed Population and Housing Census (PHC) in 2012 providing updated population figures, along with changed in administrative boundaries, emboldened an opportunity to realign the NPS sample.
The design consists of 51 design strata corresponding to a rural/urban designation for each of the 26 regions; however, Dar es Salaam is pure urban and therefore constitutes only one stratum. The allocation across the design strata was informed by the last round of the NPS and seeks to balance multiple survey objectives and maximize precision given survey parameters.
The intended sample design consisted of a new selection of 3,360 households corresponding to 420 EAs from the latest PHC in 2012. During the survey, one selected EA was demolished and subsequently not interviewed. The resulting sample consists of 3,352 households across 419 EAs.
This new cohort in NPS 2014/2015 will be maintained and tracked in all future rounds between national censuses.

Weighting
The NPS 2014/2015 household cluster weight, variable “y4_weight”, has been integrated into Section A (“HH_SEC_A”) of the household data files. 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 data files.

Mode of data collection
Face-to-face [f2f]
Supervision
The field team supervisors were trained for four days prior to the main enumerator training. The teams comprised of one supervisor, five or six enumerators, one data entry technician, and one driver.
Field teams visited each cluster for three to four 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.

Type of Research Instrument
1. Household Questionnaire: Comprised of thematic sections.
2. Agriculture Questionnaire: Collected information at both the plot and crop level on inputs, production and sales, consistent with key phases in the agricultural value chain.
3. Livestock/Fisheries Questionnaire: Administered to all households participating in these activities and asks about the inputs, outputs, labour, and sales related to these activities.
4. Community Questionnaire: Collects information on physical and economic infrastructure and events in surveyed communities.

Data Processing
Cleaning Operations
The NPS 2014/2015 contains a robust, multi-level quality assurance and data management system. The NPS utilizes a concurrent field entry system known as CAFE, or Computer Assisted Field Entry. This system was selected to increase the availability of data for review by managing staff as well as to provide regular and consistent quality assessment of data directly to the field staff.
Regular feedback was supplied to data entry staff resulting in improved quality where needed and overall efficiency.
