Focusing on the phenomenon that childbearing-age people "do not want to give birth, ""dare not to give birth," and "are unable to give birth," we comprehensively consider the three dimensions of fertility—intention, conditions, and structure, build a fertility composite index according to the relevant theories of low fertility rate, observe and analyze the current situation of low fertility rate in China, and make inter-provincial comparisons. We find that the average national fertility composite index is 0.492. The fertility condition index is the lowest, reflecting the constraints on fertility caused by employment and income factors and lack of fertility support. The structural characteristics of the childbearing-age people are consistent in all provinces, while the fertility intention and fertility conditions are spatially heterogeneous. There is a positive association between fertility index and total fertility rate. With a 0.1 unit increase in fertility index, total fertility rate increases by 0.286 units. Improving fertility intention can help effectively increase the total fertility rate; however, the changes in fertility conditions and fertility structure have not been able to effectively promote the total fertility rate. It is thus necessary to establish, improve, and implement long-term fertility support in order to reshape the fertility intention and change the behavior of the population.
