Fitted fertility rates over socio-economic status. Fertility rate over socio-economic status (SES) as fitted by our combined parametric and semi-parametric model, for age values of 18, 28, and 38, and years 2001, 2005, and 2009. Parametrically bootstrapped confidence intervals (from 1000 samples of the model) are shown for the 50% level (dashed lines) and 95% level (dotted lines). The model manages to capture various details of the fertility-SES pattern, such the time trends of fertility for the different age groups
