title: Estimation of parity progression ratios from the truncated distribution of closed and open birth intervals.
abstract: A procedure to estimate parity progression ratios in a population from the truncated distribution of open and closed birth intervals is presented. The approach is quite simple in computation and data needs. It does not require any separate data on age at last birth to the women of completed fertility as in earlier methods. The procedure is illustrated with an observed set of data.
