As is the case in many other countries, mortality has been undergoing substantial, though not precisely understood, changes in Pakistan. In the absence of a reliable and adequate system of vital registration in the country, the precise measurement of these changes is well nigh impossible. In Pakistan, an attempt to estimate levels of fertility and mortality on a sample basis was made through the Population Growth Estimation (PGE) project undertaken from 1962 through 1965 [5, 12]. Subsequently, another demographic survey, called the Population Growth Survey (PGS), was initiated and carried out from 1968 through 1971 [13]. In the PGE a dual system of data collection was utilized based on continuous (Longitudinal) registration and a periodic (Cross-Sectional) survey. In the PGS, data were collected through periodic surveys only. Data from the PGS have only recently been made available to researchers. The present set of life tables is based on the mortality statistics collected in 1968 and 1971 field operations of the PGS.

The Population Growth Estimation (PGE) experiment of Pakistan, launched in 1961 to collect data on births and deaths through a sampling approach, yielded estimates of vital rates for the years 1962 through 1965. The statistics obtained through the PGE for each of the former two wings of the country namely West Pakistan (now Pakistan) and East Pakistan (now Bangla¬desh) were included in the two reports on PGE which also provided a description of the project design and some of the results [4, 5]. The overall aim of the PGE was to arrive at reliable estimates of birth and death rates through improved coverage by the simultaneous use of Longitudinal Registration (LR) and retrospective Cross-sectional Survey (CS), which were each independently carried out in the same sample areas. The purpose behind using the two systems was that either the registration or the survey when used alone would miss some events of births and deaths which had actually occurred, whereas under the dual system if one system failed to cover some events, the other was likely to pick these up and vice versa.
