What is Panel Data (Longitudinal or cross-sectional time series data)?
Data where multiple cases ( p (individual, households, etc.)
,
,
)
were observed at two or more time periods.
What is the main purpose of Panel Data?
Helpful in monitoring the status of each household over time through analysis of several phenomena such as dimensions of poverty di i f t

Advantages of pre-survey panel data preparations ti
1.Saves more time compared to matching the households after the data collection
2.Helps ensure that all households will be covered 3.Facilitates identification of new households
(Note:
(N t new households should b given a h h ld h ld be i new HH ID)

CBMS Panel Data
Household panel data is a collection of several information about the same household over time.
Generating p g panel data entails a rigid definition of g what constitutes the same household.

Definition of “same household” over time

Guidelines on survey operations
Requirements:
1.Master li t (
1 M t list (containing HH ID names of t i i
IDs,
f members, and addresses) from first round of
CBMS
2.Spotmap with spatial locations of households and landmarks (e.g., health centers, schools,
( g churches, etc.)

Guidelines on identifying the same household
1.
1 Find at least one matched member based on the masterlist. 2.
2 If there is at least one member that matched check if that matched, household lives in the same dwelling unit as in the previous round.
3. If there is at least one member that matched and lives in the same dwelling unit, get the HH ID in the previous round of the matching member and assign it to the household. 4. If the first and the second condition are not satisfied at the same time, assign a new HH ID.

Guidelines on identifying the same household
5. For split households, use the same HH ID for the original household and assign a new ID for the new household 6. For merged households, use the same HH ID previously assigned to the HH of the current head
