This article is extensive but surprisingly doesn't discuss religion at all, which we know has been in steep decline in the west. While not specific to young people, it seems birth rates are strongly correlated to religiosity. > Model 1 confirms that women for whom religion is important in daily life have higher fertility intentions (table 4). Compared to non-religious women, who intend two children on average, women for whom religion is somewhat important intend 0.31 additional children and women for whom religion is very important in daily life intend 0.69 additional children. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2723861/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2723861/
