Constructing period parity progression ratios from household survey data.

Abstract

"An own-child analysis is applied to the household composition data of two rounds of the U.K. Labour Force Survey, each of which has a sample size of about 200 thousand people. Period parity progression ratios and the corresponding total fertility measure (TFPPR) are derived for up to twenty years before the survey date. The biases that arise when using such a source are discussed and assessed by replication using surveys in different years. Methods for correcting bias are developed. Analysis of the standard errors of the measures suggests that such sources provide the most precise, routine and timely indicators of period fertility in many situations...."
