title: Fertility decline in Germany: An econometric appraisal.
abstract: Summary   A re-analysis of Knodel's data provides some new results for the fertility decline in Germany and a new approach to testing hypotheses about the demographic transition. Two formulations of transition theory are compared: one emphasizing the importance of changing social and economic structure for fertility decline; the other, the changing relationships between fertility and its determinants over time. To evaluate these formulations, multivariate time series cross-sectional models are developed. The statistical models permit the estimation of relationships both cross-sectionally and over time. As a consequence, the ability of the independent variables to explain cross-sectional as against temporal differences is evaluated. Industrialization, urbanization, religious composition, migration, infant mortality and marriage patterns satisfactorily explain the fertility decline once regional differences have been taken into account. Persisting characteristics of regional units account for much of the unexplained variance. Industrialization is the main explanatory variable of fertility decline in Germany. In the period considered, its impact on fertility increased substantially.
