Despite the fact that Denmark is a small country, historically there have been fairly consistent regional differences in fertility rates. We apply the statistical age-period- cohort model to include the effect of these three time-related factors to concisely illuminate the regional differences in first-time births in Denmark. From the Fertility of Women and Couples Dataset we obtain data on the number of births by nulliparous women by year (1980-1994), age (15-45) and county of residence. We show that the APC-model describes the fertility rates of nulliparous women satisfactorily. To identify the regional variation an interaction parameter between age and county is necessary, and this provides a surprisingly good description, suggesting that the county-specific age-distributions of first-time fertility rates differ. Our results are in general agreement with the 'moral geography' concepts of Tonboe (2001).
