Table 2-1 Live Births by State of Occurrence Distributed According to State of Residence: United States and Each State
Residence is defined as "Unit of residence is defined as the county or county equivalent of which the mother was a resident"
Under the explanation of the tables and the source of data is the following - Birth data for the United States are confined to events registered within the United States and include events occurring to nonresident aliens. The data do not cover any vital events for U.S. citizens occurring outside the United States. Similarly, the data for Puerto Rico and the Virgin Islands are confined to events registered in these areas.
The Hawaii entries for Table 2.1
Total births occurring in the State - 17578
Birth to Residents occurring in County of Residency - 17,508
Births to non-residents - Total - 70
Births to non-residents - Intra-state non-residents - 50
Apparently in 1961 not a lot of late-stage pregnant women (50) went from the mainland to Hawaii for vacation and while there went into labor. In fact only 20 women went from one Hawaiian county to another Hawaiian county to have their babies.

Also I transposed the numbers - 50 women went from one Hawaiian county to another Hawaiian county to have their babies and only 20 women came from the mainland and had their babies.
So you don't think Hawaii is doing any "gateway" citizenship for foreigners?
Well we can all wish that were so, but I tend to be cynical. Also this theory does not comport with other articles I have read on the topic elsewhere.
I find the probability better than zero. I just don't have your kind of faith.
