The UN Volume (Bogue, Arriaga and Anderton, l993)
on population methodology has elaborated different methods for
interpolation of population data. There were two methods in
interpolating empirical data frequently discussed, that are mid-
point method and cumulation-differencing method In some cases
mid-point method was not recommended and cumulation-
differencing method was recommended only on the basis of limited
data. This study tries to explore other methods in manipulating
population data for different nature of data. The paper when at
one instance, finds that the method which was not recommended by
the said volume was acceptable using different nature of data. In
other 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 appropriate
interpolation formulae were recommended.
