    Abstract

    The Labour Force and Socio Economic Survey - 1985/86 provides
    comprehensive information on labour force charachteristics, Income
    and Expenditure and additional background information on demograhic
    characteristics of the population.

    The information on labour force are generally used to :

    (1) to study the situation and trends in employment, unemployment
    and under employment.
    (2) to quantify the magnitude and distribution of employment oppertunities
    at any point of time or over a given period of time.
    (3) to monitor the performance of employnlent programmes and of the
    economy in general.
    (4) to evaluate the impact of such programmmes on unemployment and
    under employment, income and the satisfaction of the basic needs.

    The information on income and expenditure usually serve the one or more
    of the following objectives.

    (a) To obtain weights and other useful data for planning,
    price collection or the construction or revision of
    consumer price indexes.
    (b) To supply basic data needed for policy making in
    connection with social and economic planning and to
    facilitate determination of needs or the establishment
    of targets.

    Sampling

    Sampling Procedure

    Sample Design

    Sample design is strtified two stage design. The first step was to define the sampling domains,
    for each of which an estimate desired. It was decided that the final
    estimates are required at district level and at the same time by
    sectors at all island level, In addition to this, seperat estimates are required for large
    large cities such as Colombo M.C., Dehiwala -Mt.Lavania M.C. and Kotte U.C.
    A total sample of 25,000 housing units were decided, to have 1000 housing units for
    each district on the average.

    Stratification
    Bach domain for which separate estimates are required were
    made a separate stratum. As such each sector within each district is
    a seperate stratum, in addition to the three large urban cities.

    Stages
    .,A two stage design is adopted, first stage units (PSU) being
    the Cens blocks prepared for 1981 Census of population and the
    second stage units (SSU) being the housing units. It was decided to select
    10 housing units from each. selected Census Block. Thus a first stage sample
    of 2500 census bolcks have to be selected from entire island.

    Deviations from the Sample Design

    Non completion schedules in Vavuniya, Trincomalee and Kilinochchi district were high due to the disturbances.

    Response Rate

    The response rate at all island level was 96.4%.

    Survey instrument

    Questionnaires

    The survey schedule which was canvassed to households comprised of four sections.
    The first page of the schedule collected the identification information of the household
    giving the District, Electorate, Assistant Government Agent's division, Grama Sevaka divison
    and if situated in an -urban sector, the name of the M.C., U.C. or T.C. arid if in the Rural or
    Estate sector name of the village or estate respectively. The census block number to which
    the household belongs and the number of households within that housing.unit were also recorded.

    In the control data section, information was sought on the date of visit to heusehold,
    result of the visit and the time taken to fill the schedule on each visit. The total number
    of visits made by an interviewer to a household was expected to be not more than six. visits.
    A code indicates the result of the visit in the following manner_: completed - 1, partly completed

    • 2, no competent respondent at home - 3, refused - 4, household is temporarily closed - 5
      house is demolished - 6 or any other reason under 'other' - 7. These data not only control
      the flow of the schedu les, as a schedu Ie had to be completed at least up to the control data
      for each of the selected households, but also enable to compute the different non-response
      rates such as refusal rate, demolished cases etc.

    The four major sections of the schedule are the Section 1, which deals with demographic
    characteristics of the household members, Section 2, which deals with the labour
    force which consists of persons 10 years and over, and supplementary questions in respect of
    children aged 5-14 years, youths aged 15-29 years and women in the age group 15-49,
    Section 3 deals with all sources of income received by the household members and
    Section 4 deals with the household expenditure incurred during different reference periods.

    Supervision

    The District S.Os were instructed to choose 10 housing units at random from
    5 different blocks, surveyed by 5 different Statistical Investigators for re-interviewing.
    Households in the housing units so selected were re-interviewed by the S.O. for selected
    questions of the survey schedule.
    In the instances where the responses so obtained were different from the original responses,
    they were entered in the schedule so that these entries could be clearly distinguished from
    those recorded at the initial interview. A summary report of his findings were sent to the Sample Survey Division each month. In this manner, weaker Statistical Investigators in performing field work were identified and were given instructions if it seemed necessary.

    Data Collection Notes

    Approximately 250 Statistical Investigators, who belong to the permanent
    field staff of the Department of Census and Statistics were primarily involved in the listing
    operation prior to the survey proper, and in the survey data collection operation itself. Each
    S.I. is incharge of all statistical activities in an administrative geographical unit called an
    Assistant Government Agent Division (A.G.A. Division). Each administrative district comprises
    of number of suchA.G.A. Divisions and there are altogether 256 A.G.A. Divisions
    in Sri Lanka (in the 25 administrative districts). These officers were given a thorough training
    before they were entrusted with the said survey operations. In each diStrict there is a Statistical
    Offi-cer (S.O.) who is incharge of the statistical activities in the district and one of his
    main functions is to supervise the work of the Statistical Investigators.
    The functions of the Statistical Investigators in the field for this survey were

    (a) Updating the lists of housing units of the selected blocks (PSU's) and preparation
    of listing forms (LFSE- L) as described in Part 1-3. (sample design
    and estimation procedure).

    (b) Interviewing the households in the selected housing ,units.

    A special feature in the interviewing process of the Labour Force and SocioEconomic
    Survey - 1985/86 was that, it was necessary for a Statistical Investigator to make
    at least three visits to each household allocated for him for the survey enumeration. This
    procedure was sq. adopted to enable each S.1. to collect reliable information on daily consumption
    expenditure on Food, Drink & Tobacco, for seven consecutive days, as required 'in
    the sub-section 4.1.01 of the survey schedule (see annexure for the schedule). On his first
    visit he was expected to collect necessary information under this sub-section correspondin-gto
    the day prior to the day 'of first vi'sit, which we may refer to as the first'day of the seven consecutive
    days. He was expected to make his second visit to the same household .on the third
    day after the day of first visit. On this visit he could collect the information necessary under
    this sub-section for the second, third and the fourth days of the seven consecutive days.
    On his third visit to the household which would take place on the third day after the day
    of the second visit he could collect the information necessary under the same sub-section for
    the fifth, sixth and the seventh days of the seve.n consecutive days. Investigators were expected
    to cover-up the other sections of the schedule also, during the time of. these three
    visits.

    Data processing

    Data Editing

    All completed schedules were subject to a comprehensive manual editing operation
    by a well trained group of officers at the Sample Survey Division. At this stage, schedules were checked
    for the skip pattern, impossible entries, unreasonably large values and also for internal consistency.
    The relevant field officers were contacted to get the necessary adjustment!; done, if
    it seemed necessary. Coding of the responses, to the questions which were not in the precoded
    form, was also done simultaneously with the editing operation.
    Most of the edits performed manually were incorporated in the computer edits
    and the data was 'thoroughly, cleaned before the working master files were created. The
    computer edit consisted of three parts.. ,
    (a) structural edit
    (b) range edit
    (c) edits for internal consistency, between and within sections
