"The problems that can arise in documenting trends in mean family size, parity progression ratios, mean age at birth and interbirth intervals are examined by means of the maternity histories collected in the [U.K.] General Household Survey of 1989. Methods of removing the various biases are discussed. The advantages and disadvantages of adopting each approach are discussed. The period parity progression approach to fertility measurement is the most efficient way of using maternity history information to document trends, but it is a little more complex to apply than other methods."
利用1989年英国综合住户调查收集的生育史，研究了在记录平均家庭规模、生育递进比、平均生育年龄和生育间隔趋势时可能出现的问题。讨论了消除各种偏差的方法。探讨了采用每种方法的优缺点。生育测量的时期生育递进法是利用生育史信息记录趋势的最有效方法，但它比其他方法应用起来要稍微复杂一些。
