KHDS: An Introduction
The Kagera Health and Development Survey (KHDS) is a study into the long-run wealth dynamics of households and individuals within North West Tanzania. This study entails the resurvey of a panel of households, originally interviewed for 4 rounds from 1991 to 1994. Resurveys were then organised in 2004 and 2010. A multi-topic household questionnaire is administered to all split-off households originating from the baseline households, including those that have moved out of the baseline location.
This constitutes one of the longest-running (if not the longest) African panel data set of this nature and offers an unprecedented set of research opportunities for examining long-run (nearly 20 years) and intergenerational (as the children of the original respondents have now formed their own households) trends in and mechanisms of poverty persistence and economic growth in rural households. Interviewing people who moved out of their baseline location is important for understanding how migration and economic development interlink. Finally, of note to survey innovation, the 2010 round of the survey was conducted using electronic survey questionnaires administered on handheld computers. Caeyers et al. (2010) do a detailed, formal comparison of electronic versus paper-based data collection methods, through a randomized survey experiment.
KHDS has maintained a highly successful tracking rate. The table below shows that in 2010 88% of the original 6353 respondents had either been located and interviewed, or, if deceased, sufficient information regarding the circumstances of their death collected.
Table: Status of the 6353 original respondents
|interviewed||4430 (70%)||4336 (68%)|
|deceased||961 (15%)||1275 (20%)|
|untraced||962 (15%)||742 (12%)|
|TOTAL||6353 (100%)||6353 (100%)|
The KHDS 2010 was primarily funded by the Rockwool Foundation and the World Bank, with additional funds provided by the Hewlett Foundation through the Agence Inter-établissements de Recherche pour le Développement (AIRD). The 2004 round was funded by the Knowledge for Change Partnership Trust Fund at the World Bank and DANIDA. The baseline 1991-1994 KHDS was funded by the World Bank Research Committee.

At the start of KHDS details of all respondents listed on the KHDS-1 roster in 1991/94 were recorded on a Household Tracking Form. For each member that was not living in the original village or in the immediate vicinity of it an Individual Tracking Form was filled in containing detailed information on how to reach the individual. Very often the interviewers were instructed to speak to other informants. In case this informant him or herself lived far away, an Informant Tracking Form was filled to reach him or her.
The main KHDS instrument was an elaborate Household Questionnaire. Two cards were inserted in the questionnaire. Each of these cards lines up with the rows in certain sections. The Household Roster shows the name, sex, age and ID number of each current household member. When a KHDS1 respondent is currently found to be living apart from other members his/her 1991/94 household, then these people are recorded on the Network Roster. Except for these split-off household members this roster also includes children previously recorded as living elsewhere. The network roster allows for the collection of linked relational data on the extended family.
Anthropometric measurements of all current household members were taken (even if they were not KHDS-1 respondents). These measurements were recorded on the Anthropometric Questionnaire. For all KHDS-1 respondents who died between 1991/94 and 2004 information on the circumstances of their death was collected in a Mortality Questionnaire.
Price data was collected at local markets and recorded in the Price Questionnaire. For each KHDS-1 cluster a Community Questionnaire was administered to a group of key informants, as well as a School Questionnaire in the primary school(s) in the community.
KHDS collects longitudinal data by revisiting respondents interviewed nearly 20 years ago. It is one of the few household surveys that has data over such a long period and that can address questions concerning long-term effects of childhood circumstances. It provides a unique opportunity to assess who stayed in poverty over this period and why; who moved out of poverty and how.
The sampling strategy in KHDS 2004 and KHDS 2010 was to re-interview all individuals who were household members in any wave of the KHDS 91-94, a total of 6,355 people. The Household Questionnaire was administered in the household in which these Previous Household Members (PHHMs) lived. For all household members alive during the last interview in 1991-1994, but found to be deceased by the time of the fieldwork in 2004 and 2010, information about the deceased would be collected in the Mortality Questionnaire. The next sections provide statistics of the KHDS 2004 and 2010 households.
Although the KHDS is a panel of individuals and the concept of a household after 10-19 years is a vague notion, it is common in panel surveys to consider re-contact rates in terms of households. Table 1 shows the rate of re-contact of the baseline households in KHDS 2004, where a re-contact is defined as having interviewed at least one person from the household.
Excluding households in which all previous members are deceased (17 households and 27 respondents), the KHDS 2004 field team managed to re-contact 93 percent of the baseline households. Not all 915 households received four interviews. Unsurprisingly, households that were in the baseline survey for all four waves had the highest probability of being re-interviewed. Of these 746 households, 96 percent were re-interviewed.
Turning to re-contact rates of the sample of 6,353 respondents, Table 2 shows the status of the respondents by age group (based on their age at first interview in the 1991-1994 waves). Re-interview rates are monotonically decreasing with age, although the reasons (deceased or not located) vary by age group. The older respondents were much more likely to be located if alive. Among the youngest respondents, over three-quarter were successfully re-interviewed. Excluding people who died, 82 percent of all respondents were re-interviewed.
Table 1: KHDS 2004 and 2010 Households
|KHDS 91-94||KHDS 2004 Re-interview Rates||KHDS 2010 Re-interview Rates|
|Number of interviews during 1991-1994||Re-interviewed||Deceased||Untraced||Re-interviewed||Deceased||Untraced||Total|
|54 %||10 %||37 %||54 %||10 %||37 %|
|83 %||4 %||13 %||78 %||4 %||17 %|
|86 %||1 %||13 %||78 %||3 %||19 %|
|94 %||2 %||4 %||93 %||2 %||5 %|
|91 %||2 %||7 %||89 %||3 %||8 %|
|Notes: “Re-interviewed” means that at least one member of the baseline household was re-interviewed. “Deceased” means that all Previous Household Members are reported to be dead. “Untraced” means that no Previous Household Member was re-interviewed.|
Table 2: KHDS 2004 and 2010 Individuals by Age
|KHDS 2004||KHDS 2010|
|Age at baseline 1991-1994||Re-interviewed||Deceased||Untraced||Re-interview rate among survivors||Re-interviewed||Deceased||Untraced||Re-interview rate among survivors|
|Notes: Sample of individuals interviewed in KHDS 91-94. Age categories are based on age at first interview. “Re-interviewed” means that the person was found and was re-interviewed. “Untraced” means that the person was not found or refused to be re-interviewed.|
The re-contact rates in the KHDS 2010 are in line with the ones achieved in KHDS 2004. Table 1 shows the KHDS 2010 re-contacting rates in terms of the baseline households. Excluding the households in which all PHHMs were deceased, 92 percent of the households were re-contacted.
As in KHDS 2004, households that were interviewed four times at the baseline were more likely found in 2010. Excluding the households in which all members had died, 95 percent of these households were re-interviewed in 2010.
The KHDS 2010 re-contact rates in terms of panel respondents are provided in Table 2. As in 2004, the older respondents, if alive, were much more likely to be re-contacted than younger respondents. In the oldest age category, 60 years and old at the baseline, the interview teams managed to re-contact almost 98 percent of all survivors. The length of the KHDS survey starts to be seen in this age category however, as almost three quarters of the respondents had passed away by 2010.
Table 3 provides the KHDS 2010 re-contact rates by location. More than 50 percent of the re-interviewed panel respondents were located in the same community as in KHDS 91-94. Nearly 14 percent of the re-contacted respondents were found from other region than Kagera. The survey team also tracked panel respondents in Uganda where one percent of the interviewed panel respondents were located.
The location of the untraced respondents is based on the tracking data. More than half of the untraced respondents are reported to be living in Kagera.
Table 3: KHDS 2010 Re-Contact Rates by Location
|Elsewhere in Kagera||24|
|Dar es Salaam||9|
|Other country (b)||8|
|Notes: Location for untraced respondents is reported by other household members from the baseline survey who were successfully located, interviewed, and able to provide location information on the respondent. In some cases, this information comes from other relatives or neighbours residing in the baseline communities.
a. KHDS 2010 tracked international migrants in Uganda only.
b. Countries to which the 58 untraced respondents had moved are: Burundi, Denmark, Kenya, Norway, Rwanda, South-Africa, Sweden, UK and USA.
Location of households in 2004
Note to the figure above: “Traced” means that there was adequate address information for at least one surviving household member during the initial field visits in October – November 2004. Subsequent field work from January – May 2004 yielded additional information, which increased the number of traced households, and this is not reflected in the statistics presented here

RATIONALE: Absence of district level survey data does not rhyme with the devolution of power to districts. Tanzania is undergoing a decentralisation process whereby each of its roughly 128 districts is becoming an increasingly important policy actor. A district taking on this challenge needs accurate information to monitor and develop its own policies. Much relevant information is currently not available as national statistics are not representative at district level and many of the routine data collection mechanisms are still under development. CWIQ then provides an attractive, one-stop survey-based method to collect basic development indicators. Furthermore, the survey results can be disseminated – through Swahili briefs and posters – to a district’s population; thus increasing the extent to which people are able to hold their local governments accountable. Exciting new ground is being broken on such population-wide dissemination by the Prime Minister’s Office.
METHODOLOGY: The data are collected through a small 10-page questionnaire (downloadable below), called the Core Welfare Indicators Questionnaire (CWIQ). The questionnaire and data software constitute an off-the-shelf survey package developed by the World Bank to produce standardised monitoring indicators of welfare. The questionnaire is purposively concise and is designed to collect information on household demographics, employment, education, health and nutrition as well as utilisation and satisfaction with social services. Questionnaires are scannable, with interviewers shading bubbles and writing numbers later recognised by the scanning software. The data system is fully automated allowing the results to roll out within weeks of the fieldwork.
FUNDING: projects are typically funded by organisations that care about making decentralisation work in Tanzania. CWIQ is a method to promote evidence-based policy formulation and debate in the district and a tool for the population to hold their local governments accountable. With funding from the RNE (Royal Netherlands Embassy) and SNV (Stichting Nederlands Vrijwilligers), CWIQ surveys were implemented between 2003-2005 in 16 districts. In 2006/07 PMO-RALG (Prime Minister’s Office – Regional Administration and Local Government) commissioned EDI to cover a further 28 districts. In 9 of these districts this constituted a repeat survey and thus a unique opportunity arises to monitor changes that occurred in the district over this time period.
DISSEMINATION: EDI disseminated the results of CWIQ on posters and briefs to district level stakeholders (councillors, district officials, NGOs, CBOs, Advocacy Groups, MPs, ‘interested citizens’, etc.), with the aim at district level, to: (i) promote evidence-based policy debate, (ii) promote evidence-based policy formulation, (iii) provide tools for district level M&E and (iv) increase accountability of LGA to citizens.
PUBLIC DOMAIN: Currently in the public domain are (i) all CWIQ reports – note that Shinyanga 2004 and Kagera 2003 reports are organised into one region-wide report (ii) Swahili and English briefs for 5 pilot dissemination districts funded by the Prime Minister’s Office – and (iii) raw data for all CWIQs conducted between 2003 and 2007.

SHWALITA – probably the most exotic name that has ever been conjured up for an EDI research project – is short for ‘Survey of Household Welfare and Labour in Tanzania’. It is a unique experiment in survey design that Joachim De Weerdt and the team at EDI conducted on behalf of the University of Dar es Salaam and the World Bank. The project was developed by the Living Standards Measurement Study (LSMS) Team in the World Bank in collaboration with the University of Dar es Salaam and EDI. The survey experiment is an important component of the LSMS’ multi-year research agenda in survey methodology (LSMS Phase IV).
The consumption experiments in the survey benefited from substantial inputs from John Gibson at the Waikato Management School, Adolf Mkenda at the University of Dar es Salaam, Jed Friedman and Peter Lanjouw from the World Bank; the labor experiments from the inputs of Elena Bardasi from the World Bank and Andrew Dillon from IFPRI; and the subjective welfare experiment from inputs by and Adelbertus Kamanzi from Uganda Martyrs’ University. Kathleen Beegle of the LSMS team is task manager of the project. Other members of the LSMS team include Kinnon Scott, Calogero Carletto, Diane Steele and Kristen Himelein.
This 4,000 household survey randomly assigns 8 slightly different survey modules to its respondents. The survey modules reproduce 8 different ways in which research projects across the globe have aimed at measuring households’ welfare. In addition, the instruments aim at validating the way labour allocation and subjective welfare can be measured. By randomly assigning households to certain modules, the goal is to highlight differences in outcomes that are purely related to the research design, but do not reflect ‘real’ differences.
This survey consists of 3 separate experiments, carefully bundled into one survey: (i) consumption experiments (ii) labour module experiments (iii) subjective welfare experiments, conducted electronically on CWEST, which was EDI’s precursor software to Surveybe.
On this page you will first find publications made on this dataset and then some more detailed explanations of each of SHWALITA’s components, its sample and cluster locations.
The rationale behind the CONSUMPTION EXPERIMENTS comes from the observation that there are large and growing gaps between micro and macro estimates of household consumption. These discrepancies have profound implications for measuring global progress in poverty reduction and the effect of economic growth on that process. Currently it is difficult to reconcile these differences due to the wide variation in methods used to measure household consumption. While macro measures are broadly consistent around the world, under the SNA framework, micro measures of household consumption have no such standardization. Household expenditure surveys vary widely across many dimensions, including: the method of data capture (diary versus recall), the level of respondent (individual versus household), the length of the reference period for which consumption is reported (varying from 3 days, to one week, to one year) and the degree of commodity detail in recall surveys (varying from less than 20 to over 400 items). These variations occur both across countries and also over time as statistical offices alter survey design, with little understanding of the implications of such changes for spatially and temporally consistent measurement of household consumption and poverty. This variation hampers both cross-country studies of poverty and well-being measures as well as measuring poverty trends within country. This experiment implements alternative methods to measure household consumption.
The researchers developed eight alternative consumption questionnaires which were randomly distributed across 4,000 households. These eight designs vary by method (3 diaries and 5 recall modules), length of reference period in recall modules, and the number of items in the recall modules. In addition to assessing how the alternative methods affect consumption calculations and household rankings, the evaluation will include a comparison of costs across numerous dimensions: length of field work (in part based on length of interview which will be recorded), coding and data entry inter alia. The study also assesses the sensitivity (robustness) of poverty line calculations where the food poverty is based on calorie assignment of food groups in turn affected by level of disaggregation of food items.
The LABOUR EXPERIMENTS assess the effect of different ways of collecting labour statistics. It uses two different modules, a long module and a short module, and administers each to either the person him/herself or to someone else in the household answering on their behalf (a proxy respondent). Both proxy respondents and self-reporting respondents are sampled randomly from the roster of household members.
The SUBJECTIVE WELFARE EXPERIMENTS use an innovative approach to enhance comparability of subjective welfare questions. The technique, developed in political sciences by Gary King, involves the respondent to provide scaled answers on qualitative questions (on a scale of 1 to 5, how do you feel about….). In order to ‘anchor’ the response the respondent is given a ‘vignette’ a short, but powerful story about a fictitious person and is then asked to place this person on the same scale. The placing of the vignette on the same scale allows answers to become more comparable across households, communities and countries. Data were captured electronically through CWEST.
Sampling & Module Assignment
The 7 districts covered in this project were previously surveyed through EDI’s CWIQ project (see tab at the top of this page for more detail), in which a sample of households was drawn to be representative at district level. Data from the 2002 Census was used to put together a list of all villages in the district. In the first stage of the sampling process villages were chosen proportional to their population size. In a second stage the sub-village (kitongoji) was chosen within the village through simple random sampling. In the selected sub-village, or cluster all households were listed. Shwalita makes use of CWIQ’s sampling frame to randomly select 24 clusters out of the 30 CWIQ clusters and draw its random sample of households from the CWIQ listing forms. The following table shows the selected districts and is sorted in the order in which they will be visited.

Finally, the subjective welfare questionnaire will be administered to 576 households (4 households in each of 24 clusters in each of 6 districts) and will be downloadable from this site soon.
The survey teams will visit 168 communities. In each community the nearby shops, stalls and markets will be visited to collect local price data (download price questionnaire). Additionally, a structured community questionnaire will be administered to key informants in each community (download English – download Swahili). The community questionnaire contains a price opinion section as an alternative way to collect prices. For a good discussion on various price collection mechanisms in surveys see Gibson and Rozelle’s WBER article.
EDI began piloting questionnaires and training interviewers from June 2007 onwards. Fieldwork started beginning of September 2007 and is expected to last till end of June 2008. In order to keep tight control implementation, the fieldwork is conducted by a relatively small number of 12 interviewers and spread over a longer time period. Such a set-up avoids the typical co-ordination problems faced by larger-scale fast-moving set-ups and allows for maximum control from the project management and co-ordination team. Ultimately it seems like a necessary condition to achieve an acceptable level of non-sampling error.
