Fertility in Northern Ireland Total Births Age Specific Fertility Rates
Education and fertility Static economic analysis Children assumed to be normal ‘goods’ and the decline in fertility with income explained by child ‘quality’: the income elasticity of quality (+ve) being greater than the income elasticity of quantity (-ve). The home production framework allows the cost of children to be expressed as a function of the parents’ wages and their respective shares in the costs of producing child quality Education and fertility
Dynamic economic analysis The ‘user cost’ of a child now is a function of a sequence of prices such as the female wage rate The optimal profile of a woman’s stock of human capital will be jointly determined with the timing of the births of her children. Any empirical analysis should permit the demographic profile to vary with educational attainment Education and fertility

The NILS • The NILS potential mothers: those women with health card registrations, aged 16-44 years and whose DOB is one of the 104 in the systematic sample • Registrations downloaded biannually and constitute potential panel members • Details of any birth to a NILS mother are forwarded by the GRO to the NILS • 2001 Census: An attempt is made to link the Census details of all NILS mothers The NILS
