Tracking in Longitudinal Household Surveys Firman Witoelar World Bank
Why tracking? Attrition is an inherent in problem in longitudinal surveys, primary cause: respondent moving from original location Tracking: following respondents who move out of their original dwelling Why tracking? helps lower attrition: minimize reduction in statistical power by keeping sample size mitigate potential biases in the analysis if attrition is selective Example: a panel study on income mobility that only includes respondents who did not move will underestimate income mobility, if those who moved are younger, more highly educated people potentially valuable information from movers: information about long distance movers who were tracked and interviewed may be valuable those who were not found at all
Why tracking? surveys may have specific study aims that require tracking Example: survey that aims to study migration require tracking of respondents who move and migrate survey that aims to study marriages may require tracking of young respondents if, for example. marriages and migration decisions are closely linked
Recent experience suggest that tracking is important and valuable for longitudinal household surveys Ongoing and future longitudinal surveys should seriously consider tracking respondents who move, in particular not only track those who move from their old dwellings, or move within the same village, but also those who move outside the localities. However, Tracking is hard: population are mobile, infrastructure poor, address system/official records may not exist Tracking is costly: monetary, time, and also require high capacity of the organization that conduct the survey
Common approach in tracking Common approach in tracking in: to track households over time Some conceptual problems with following households households split, dissolve, and combine arbitrariness of original household panel household a vague concept
Wave 1 Wave 2 John (head of household) Mary (spouse of head) Adam (son 1) Bob (son 2) Cindy (daughter) John (head of household) Mary (spouse of head) Adam - left Bob (son 2) Cindy (daughter) Adam (head of household) Elizabeth (spouse of head), new respondent John (head of household) Mary (spouse of head) Adam (son 1) Bob (son 2) Cindy (daughter) John - left Mary (head of household) Adam - left Bob (son 2) Cindy (daughter) Adam (head of household) Elizabeth (spouse of head), new respondent John (head of household)
Wave 1 Wave 2 John (head of household) Mary (spouse of head) Adam (son 1) Bob (son 2) Cindy (daughter) John - left Mary - left Adam (head of household) Bob - left Cindy - left Village A Village A John (head of household) Mary (spouse of head) Bob (son 2) Cindy (daughter) Village B John (head of household) Mary (spouse of head) Adam (son 1) Bob (son 2)Cindy (daughter) John - left Mary (head of household) Adam - left Bob (son 2) Cindy (daughter) Adam (head of household) Elizabeth (spouse of head) John (head of household)
Conceptual difficulties in defining panel households Lead to practical problems: assigning household ID More useful to view tracking as following individuals: even though in many cases, entire household moves and the whole household is tracked
Who to track Baseline survey is representative of particular population Who to track: depends on the aims of the study Who to track: affects cost and length of the survey Difficult to set the rule before actually know the numbers Important to note that the rule on who to track may affect representativeness of the sample Methods exist to re-weight the sample to recover some of the representativeness Definitions: tracking targets and interview targets Tracking target: a respondent who, when he/she moves, has to be followed. Whether an individual is a tracking target has to be clearly identified in the household rosters. Interview target: a respondent that needs to be interviewed. Some interview target may not be tracking target. Example
Study aim: to focus on migration of youth. Tracking rule: track anyone age 10-29, interview anyone interviewed in wave 1, also spouse and children of tracking target Wave 1 Wave 2 John (head, 55 years) Mary (spouse, 51 year) Adam (son, 22 years) Bob (son 19 years) Cindy (daughter, 18 years) John - left (Not a tracking target) Mary (head) Adam - left (Tracking target) Bob (son 2) Cindy (daughter) Adam (head of household) Elizabeth (spouse) new respondent, interview target John (head) Not tracked
Some criteria used in existing survey Based on list of interview targets in the baseline survey Based on the relationship to the household head Based on certain demographic characteristics
Organizing tracking operation Fieldwork organization: fieldwork typically conducted by several teams each responsible for a number of sample EAs, with predetermined routes and time schedule (mobile teams) With tracking: more coordination is needed from the survey organizer teams may need to interact with each other routes and schedule more flexible: coordinated and decisions made by survey organizer
Organizing tracking operation Possible survey phases main survey phase : teams go to assigned sample EAs Possibly local tracking (movers who live near sample EAs) Respondents from other teams (especially in urban areas) tracking phase: smaller teams more places, longer distance outside sample EAs,
Organizing tracking operation Important to have a group of people/someone responsible in managing tracking Tracking management team/ a tracking shop / a tracking manager Responsibilities: Combining information from Tracking Forms Solving conflicting information Evaluating quality of information (completeness and of Tracking Forms) Prioritizing tracking cases Evaluating trade-offs between cases: e.g. 2 households nearby or 5 far away? Assigning cases to teams Keep track of the extent of mobility/migration: may need to have a break after a few weeks to assess mobility
Organizing tracking operation One alternative to breaking the survey midway: conduct a pre-survey tracking pilot where interviewers use household rosters from previous round to see how many households/household members have moved can select several EAs instead of all EAs: the goal is to make rough assessment of the extent of mobility if there household listings are updated between rounds, this tracking pilot can be conducted in conjunction with the listing activities
Organizing tracking operation Possibility of dedicated tracking teams In specific areas known to be destination areas for migrant (e.g. urban, industrial centers) Tracking teams: Higher quality interviewers if no supervisors for small teams (e.g. 2 people) Mobile, persistent Have knowledge of the areas
How far should respondents be tracked? Establish the limits on how far targets should be tracked Administrative boundaries: to establish the administrative units outside which the track targets will not be followed by any team only district which is part of the study area? out of sample districts? out of country? implications: permissions from local government, etc. Geographical boundaries: within which all tracking targets will be followed e.g distance, terrains Allow some flexibility: suppose a cluster of households move just outside the district. Valuable information will be lost if these households are not tracked. Tracking Manager has to make decision whether to track these households even they are located outside the predetermined limits
Tracking protocols Verifying the dwellings For example, when interviewers go back to the village and look for John s family, the person who answers the door says that John s family don t live there. Interviewers have to verify that: they indeed come to the correct dwellings where John s family used to live verify that John s family do not live there Identifying movers: interviewers use household rosters to identify who have moved If those who live in the dwelling say that John s household have moved, interviewers still need to verify that each household members have really moved If only some of John s family have moved, identify the movers and check whether the movers are tracking targets
Tracking protocols Getting information about where the household/household members move to: Obtain multiple informants Collect information from informants (Tracking Forms)
Potential informants The entire household move: neighbors, village officials, relatives, places of work, schools, stores/markets, people from the same church/mosque, people in places the target usually spend time/hang out, etc. Only some household members move: household head, other household members. But also: neighbors, village officials, relatives, places of work, schools, stores/markets, people from the same church/mosque, people in places the target usually spend time/hang out, etc.
Collecting information Household Rosters/Forms with pre-printed/pre-loaded information Tracking Forms : to record information about households or individuals who move, may also have tracking forms for informant Send completed Tracking Forms to the headquarters immediately/as soon as possible Information collected About the informants: phone numbers, address/route, phone numbers, email address, work place and work numbers, informants relationship to the tracking targets About the tracking targets: street address of the tracking targets, telephone numbers, route to reach the new address, maps/sketch of location new and old work places: names of the companies/employers/places of work, addresses and phone numbers. places where the tracking targets used to spend time/hang out, or new places the tracking targets are known to spend time

Tracking Other ways to improve tracking: - official/unofficial records: birth, marriage, death, church membership, schools, etc - use information from other modules in the survey collected in previous rounds - use mobile phones: to contact informants and tracking targets, verify addresses, make appointments - GPS backtracking: may depend on the feature of the GPS device - incentives to households - incentives to teams
Conducting interview with the tracked respondents Assigning household and individual ID Completing household rosters Conducting the interview Assigning household and individual ID: very critical but could be overlooked Household and individual ID have to uniquely identify household and individual within round IDs have to be designed so that the households and individuals from different rounds/waves can be linked correctly Examples
Assigning household and individual ID Household ID and individual ID must uniquely identify household and individual With tracking, need to assign new HHID to split off HH Several options on how to assign HHID in the next wave IFLS: original HH get same HHID, others get new ones KHDS: all HH get new ID by adding 01, 02, to the end of the old HHID MTM: all HH get new ID using old HHID and old roster number
Some different ways to assign HHID (1) Assign original HHID to one of the households, and assign new HHIDs to the split-off households.
Wave 1 Wave 2 HHID: 11010200 01 John (head of household) 02 Mary (spouse of head) 03 Adam (son 1) 04 Bob (son 2) 05 Cindy (daughter) HHID: 11010200 01 John (head of household) 02 Mary (spouse of head) 03 Adam - left 04 Bob (son 2) 05 Cindy (daughter) HHID: 11010201 01 Adam (head ) 02 Elizabeth (spouse), new respondent HHID: 11010200 01 John (head of household) 02 Mary (spouse of head) 03 Adam (son 1) 04 Bob (son 2) 05 Cindy (daughter) HHID: 11010200 01John - left 02 Mary (head) 03 Adam - left 04 Bob (son 2) 05 Cindy (daughter) HHID: 11010201 Adam (head) Elizabeth (spouse, new respondent) HHID: 11010202 John (head)
Wave 1 Wave 2 HHID: 11010200 01 John (head of household) 02 Mary (spouse of head) 03 Adam (son 1) 04 Bob (son 2) 05 Cindy (daughter) Village A which one is original? HHID: 11010200 01 John - left 02 Mary - left 03 Adam (head of household) 04 Bob - left 05 Cindy - left HHID: 11020201 01 John (head of household) 02 Mary (spouse of head) 03 Bob (son 2) 04 Cindy (daughter) Village A Village B HHID: 11010200 01 John (head) 02 Mary (spouse ) 03 Adam (son 1) 04 Bob (son 2) 05 Cindy (daughter) Watch out for duplicate HHIDs John - left Mary (head of household) Adam - left Bob (son 2) Cindy (daughter) Adam (head of household) Elizabeth (spouse of head) John (head of household)
Some different ways to assign HHID (2) Assign new HHIDs to all households in each round by simply adding two digits (01, 02, 03, ) at the end of the old HHID: for example HHID number was 110102, then the 3 new households interviewed will be numbered: 11 01 02 01 11 01 02 02 11 01 02 03
Wave 1 Wave 2 HHID: 11010200 01 John (head of household) 02 Mary (spouse of head) 03 Adam (son 1) 04 Bob (son 2) 05 Cindy (daughter) HHID: 11010201 01 John (head of household) 02 Mary (spouse of head) 03 Adam - left 04 Bob (son 2) 05 Cindy (daughter) HHID: 11010202 01 Adam (head ) 02 Elizabeth (spouse), new respondent HHID: 11010200 01 John (head of household) 02 Mary (spouse of head) 03 Adam (son 1) 04 Bob (son 2) 05 Cindy (daughter) HHID: 11010201 01John - left 02 Mary (head) 03 Adam - left 04 Bob (son 2) 05 Cindy (daughter) HHID: 11010202 Adam (head) Elizabeth (spouse, new respondent) HHID: 11010203 John (head)
Some different ways to assign HHID (3) Assign new HHID to all households by using the old HHID and add to that the roster number of the tracked respondents in that households (could be 01, 02, 03... up to how many members were in baseline).
Wave 1 Wave 2 HHID: 11010200 01 John (head of household) 02 Mary (spouse of head) 03 Adam (son 1) 04 Bob (son 2) 05 Cindy (daughter) HHID: 11010201 01 John (head of household) 02 Mary (spouse of head) 03 Adam - left 04 Bob (son 2) 05 Cindy (daughter) HHID: 11010203 01 Adam (head ) 02 Elizabeth (spouse), new respondent HHID: 11010200 01 John (head of household) 02 Mary (spouse of head) 03 Adam (son 1) 04 Bob (son 2) 05 Cindy (daughter) HHID: 11010202 01John - left 02 Mary (head) 03 Adam - left 04 Bob (son 2) 05 Cindy (daughter) HHID: 11010203 01 Adam (head) 02 Elizabeth (spouse, new respondent) HHID: 11010201 01 John (head)
Linking individuals between rounds/waves Need to be able to link individuals between rounds/waves Typically done after fieldwork Very important to get this right An example:
Wave 1 Wave 2 HHID: 11010200 01 John 1101020001 02 Mary 1101020002 03 Adam 1101020003 04 Bob 1101020004 05 Cindy 1101020005 HHID: 11010201 01 John 1101020001 02 Mary 1101020002 03 Adam 1101020003 04 Bob 1101020004 05 Cindy 1101020005 HHID: 11010202 01 Adam 1101020003 02 Elizabeth 1101020202
Completing household rosters Which information should be fed-forward to the new roster: age, sex, birth date, etc. What to do with conflicting information Identifying tracking targets (are there any tracking targets who still need to be tracked) Collect basic information about those who are still not found (very valuable): Birth date (can be preloaded and confirmed during the interview) Sex Date when they left Village/City/Region where they moved to Reason they left Highest education known by informant Working status, marriage status, and other key information Identifying interview targets Conduct interviews
