What factors do you think contributed to the steady increase in births to unauthorized immigrants from the S's to the early 2000s?

The steady increase in births to unauthorized immigrants from the 1970s to the early 2000s can be attributed to several factors, including higher Immigration rates during this period, as many individuals sought better economic opportunities and family reunification. Additionally, many unauthorized immigrants tend to be of childbearing age and often have larger families due to cultural norms and limited access to family planning resources. The relative stability of certain immigrant communities also encouraged family growth, as individuals felt more secure in their environment.
