Introduction
• The labour force estimates are obtained from a
quarterly sample survey of households
• Survey Name - CSSP Continuous Sample Survey of
Population
• The Continuous Sample Survey of Population
(C.S.S.P) was designed as a multi-purpose
household survey in 1963 with its primary
objective being to provide up-to-date data on the
labour force characteristics of the population of
Trinidad and Tobago on a continuing basis

Sample Frame
• The Sample is drawn from a master sample frame
which was derived from the 1990 Population and
Housing Census
• The Frame comprising a listing of EDs
• The master sample frame contain approx. 2/3 of
all EDs
Sample Design
• The CSSP is based on a stratified cluster design
in which clusters of households or
Enumeration Districts (EDs) consisting
approximately 150 to 200 households
constitute the Primary Sampling Units (PSUs)
and the households within each ED constitute
the Ultimate Sampling Units (USUs.)
Sample Design
• Households are sampled utilizing a two-stage
selection process. At the first stage ED’s are
sampled with probability proportional to size
(PPS). Using the available size estimates of
households in the ED’s. At the second stage
households within each selected ED are sampled
with probability inversely proportional to size
(PPS-1)
• the probability of selection of second state units
remain fixed throughout the life of the sampling
frame
Sample Size
• Currently, the sample size for the labour force
survey is approximately 3,044 households per
quarter selected from approximately 378 EDs,
an average of 8.1 households per ED.
• The sample is geographically representative by
Administrative area
• Enumeration during a quarter is conducted in 6
periods or rounds
Coverage
• All administrative areas in Trinidad and Tobago
• Non-Institutional population of individuals who
are 15 years of age or older
• Unit of analysis: Private Households within
private dwellings
• Reference period is the past week

Paper questionnaires
EDs listed before enumeration
Number of households in the Ed is used to
compute the number of USU/households to
be interviewed
• Field supervision
• Return of questionnaires to office
Survey Processing
• Edited and coded
• Manual data entry
• Electronic data is then edited and verified by
a validation program
• Apply raising factors
• Tabulations produced
Questionnaire
• Demographic characteristics – age, sex, ethnic
group, education, place of birth, marital status
• Economic activity – type of worker,
occupation, industry, hours worked, income
• Housing – tenancy, type of dwelling, toilet
facilities, water supply, source of lighting
Estimation
• Estimation of the number of persons employed is
done by gender
• Sample estimates are inflated to population
estimates by sex based on the population ratio
estimation method
• Separate raising factors for Trinidad and Tobago
allows the provision of independent quarterly
estimates of the Labour Force by island
• The estimate of the number of persons in the
population aged 15 and over, by gender, which is
obtained from a source that is independent of the
labour force survey, is centered at the middle of
each quarter
Concept of the Unemployed
• Total Unemployed = Persons Seeking Work +
Other Unemployed
Persons Seeking work:
• Persons without jobs during the reference week
and were actively seeking employment during
the said reference week
Concept of the Unemployed
Other Unemployed
• Persons who were without jobs during the
reference week, who did not look for work during
the reference week, but who did look for work at
most three months before the reference week.
Such persons must provide valid reasons for not
looking for work during the reference period which
are limited to the following:
Concept of the Unemployed
• They were discouraged from seeking work
• They were awaiting results of previous
applications for employment
• They were temporarily ill and could not look for
work during the reference week
• They wanted jobs but did not know of anywhere
to get suitable employment
Concept of the Unemployed
• The unemployed is classified into occupational
and industrial groupings according to ISCO and
ISIC respectively according to last occupation/job
held if employed previously, or according to
occupation/job sought if never was employed
Employed
• Total Employed = Persons with jobs who
worked during the reference period + Persons
with jobs who did not work during the
reference period
• A Job is defined as any economic activity, in
which a person is engaged for pay whether in
cash or kind, regardless of the duration of
work, since work takes precedence over any
other activity
