Pakistan (2005): National Survey on Family Planning and Reproductive Health

The survey was requested to collect data on reproductive health, fertility and family planning and their determinants in order to provide the sponsors with information useful for evaluating and improving their programs and activities relating to reproductive health and family planning. Initially, it was envisaged to use the services of Federal Bureau of Statistics to draw upon their sampling frame and sampling strategy and pulling out a representative sample. When this could not materialize, Oasis was asked to construct a sampling frame and pull out a representative sample. FBS follows a two stage probability sampling design for its studies. In the first stage it draws PSUs within each stratum using random sampling procedure. In second stage it prepares the list of all households (SSUs) within each selected PSU to draw a systematic sample of households.
