LSMS-ISA: Tanzania Map

NEW - The data from the 2008-2009, 2010-2011, 2012-2013, and 2014-2015 National Panel Surveys are now available for downloading free of charge.

Overview

The LSMS-ISA project is supporting the design and implementation of the Tanzania National Panel Survey (TZNPS), with a focus on expanding the agricultural content of the TZNPS, and ensuring comparability with other surveys being carried out under the LSMS-ISA project in Sub-Saharan Africa. The emphasis is to ensure that information on agriculture and livestock, and data on food and nutrition security inter alia, are mainstreamed into the TZNPS, and that the quality and relevance of these data is further improved and sustained over time. The TZNPS is implemented every two years; the first round of data collection ran from October 2008 through September 2009. Donors for the first round of data collection included the Government of Tanzania, Kingdom of Denmark, United Nations Children’s Fund (UNICEF) and United Nations Population Fund (UNFPA). The second round of data collection was collected from October 2010 and completed in December 2011. Similarly, the third round of data collection lasted from October 2012 to December 2013. The main source of funding for the second and third round was the European Union with technical assistance funding provided by the World Bank with funding from the Bill and Melinda Gates Foundation.

Management

The TZNPS is implemented by the Tanzania National Bureau of Statistics (NBS). The LSMS team is responsible for the management and technical design of the project, as well as for the provision of technical assistance and the support of analytical work resulting from the collected data.

Design

Sampling and Survey Design

The TZNPS sample for the first round was 3,265 households, half of whom had been surveyed for the 2007 Tanzania Household Budget Survey (THBS). The sample is representative for the nation as a whole, and provides reliable estimates of key socioeconomic variables for mainland rural areas, Dar es Salaam, other mainland urban areas, and Zanzibar. For 25 percent of the sampled households, areas of all owned and/or cultivated agricultural plots were measured via GPS.

In the second round, all original households were targeted for revisit. Those members still residing in their original location were re-interviewed, and all adults who had relocated were tracked and re-interviewed in their new location with their new households. The sample size for the second round subsequently expanded to 3,924, and all accessible plots were measured via GPS. The third round adhered to the same tracking protocol as the second round resulting in a final sample size of 5,015 households.

In the fourth round, the sample was refreshed. The refreshing of the longitudinal sample realigns the sample with changes in administrative boundaries, demographic shifts and updated population information. Similar to the sample in NPS 2008/2009, the sample design allows analysis at 4 primary domains of inference, namely: Dar es Salaam, other urban areas on mainland Tanzania, rural mainland Tanzania, and Zanzibar. The new sample consists of 3,352 households corresponding to 419 EAs from the latest PHC in 2012. This new cohort in NPS 2014/2015 will be maintained and tracked in all future waves between national censuses.

Implementation

Field Work Implementation

The questionnaires for the TZNPS were administered via a single visit to the households. The field work is implemented with mobile teams and concurrent data entry, developed in CSPro. Additionally, one or two mobile tracking teams were responsible for tracking households and individuals that had moved far away from the local of their original EA. Second data entry is performed at NBS headquarters in Dar es Salaam.

Methodological Validation

For 25 percent of the sampled households, areas of all owned and/or cultivated agricultural plots within 25 kms of the household have been measured using GPS technology in the first round. In all subsequent rounds, all owned and/or cultivated plots within 1 hour of the household by any means of transportation are measured.

Dissemination

Data Documentation and Dissemination

All data generated are made publicly available (fully cleaned and with complete documentation) within twelve months of completion of each wave of data collection. The TZNPS data are disseminated via the LSMS and NBS websites.

The data from the 2008-2009, 2010-2011, 2012-2013, and 2014-2015 National Panel Surveys are now available for downloading free of charge.
