The decline in total fertility rates in Western countries, particularly the Nordic countries, has puzzled demographers. Researchers assume that the decline is associated with increasing perceptions of uncertainties about the future. In this study, we explore whether childbearing intentions have also declined and whether individuals have become more uncertain about future childbearing. To do so, we compare childbearing intentions expressed by participants in the 2012 and 2021 Swedish Generations and Gender Surveys. We present multinominal logistic regressions of respondents’ answers to the question whether they definitely or probably intend to have a(nother) child in the next three years and (if not) whether they (ever) intend to have a(nother) child in the future. Our findings indicate that the intentions to definitely have a(nother) child have declined across socio-demographic groups, and that uncertainties about future childbearing have increased. These changes were particularly pronounced among young people and among childless respondents, indicating a growing indecision as well as a growing tendency to remain childfree among groups that are relevant for future fertility development. The decline in intentions and the increase in uncertainties about childbearing indicate that the ongoing fertility decline cannot be classified as a temporary phenomenon. Rather, the results suggest that the decline will continue, because childbearing intentions are rarely fully realized. Our results are a step toward unraveling the puzzle of declining fertility in the Nordic region and beyond. The findings reveal that individuals have become more uncertain about future childbearing and that they have become more likely to retreat from childbearing.
