It might be quite difficult to navigate the ambivalences in the CDC dataset because the data provided by the fertility clinics are not accessible to the public and some clinics are not reporting data. Also, the dataset itself lacks explanation and contextualization.
Although the CDC data is open to access, it might only be circulated within academic circles. Also, the datasets lack elaborate descriptions and contextualization to be eligible for the broader population.
The CDC's ART data mostly focuses on total fertility rate based on the increasing age of the patient. Whereas the age is a significant factor, there are many other factors determining fertility, which are not covered in this dataset. This lack might cause a limited understanding of fertility.
