<jats:p>The socio-economic databases in Pakistan, as in most
countries, can be classified into three broad categories, namely
registration-based statistics, data produced by different population
censuses and household survey-based data. The registration system of
births and deaths in Pakistan has historically been inadequate [Afzal
and Ahmed (1974)] and the population censuses have not been carried out
regularly. The household surveys such as Pakistan Demographic Survey
(PDS), Labour Force Survey (LFS) and Household Income Expenditure Survey
(HIES) have been periodically conducted since the 1960s. These surveys
have filled the data gaps created by the weak registration system and
the irregularity in conducting censuses. The data generated by the
household surveys have also enabled social scientists to examine a wide
range of issues, including natural increase in population, education,
employment, poverty, health, nutrition, and housing. All these surveys
are, however, cross-sectional in nature so it is not possible to gauge
the dynamics of these social and economic processes, for example the
transition from school to labour market, movement into or out of
poverty, movement of labour from one state of employment to another. A
proper understanding of such dynamics requires longitudinal or panel
datasets where the same households are visited over time. Since panel
surveys are complex and expensive to carry out, they are not as commonly
conducted as the cross-sectional surveys anywhere in the world and in
Pakistan they are even rarer</jats:p>
