The UN Volume (Bogue, Arriaga and Anderton, l993)on population methodology has elaborated different methods forinterpolation of population data. There were two methods ininterpolating empirical data frequently discussed, that are mid-point method and cumulation-differencing method In some casesmid-point method was not recommended and cumulation-differencing method was recommended only on the basis of limiteddata. This study tries to explore other methods in manipulatingpopulation data for different nature of data. The paper when atone instance, finds that the method which was not recommended bythe said volume was acceptable using different nature of data. Inother case, the method which was recommended in the volume was_,round more sound in respect of other kind of data In addition,some new types of data have also been tried and appropriateinterpolation formulae were recommended. |
