In Hungary, where current fertility is below replacement, it is important to explore
the fertility intentions of potential future parents. In our paper, we use a novel
representative database to explore the future childbearing intentions of young adult
Hungarians (18–29) and to estimate the potential effect of a wide range of demographic,
socioeconomic and value-related independent variables. According to our results, fertility
intentions are shaped by the individual’s economic status, current domicile, parental
education, religiosity, parental separation, relationship status and positivity towards
Hungary. Additionally, interaction models show that fertility intentions vary by age
and gender: a critical period of late young adulthood is highlighted when stronger
intentions notably decline for women. Finally, using subsamples, we examine the effect
of climate anxiety and green behaviour. Results suggest that those who plan to have
more children are more likely to behave in an environmentally conscious way.
