Researched from primary sources

Trans Data Initiative research. Researched from primary sources (enacted text, the code on official sites, executive orders, court orders), starting from the Trans Data Initiative legislation tracker's bills. Each determination was checked independently by a second researcher; disputes were settled by a third review. No other tracker's descriptions were used.

A record is what a source reported on the date it was captured, not a legal effective date. An unobserved record is not a finding that no restrictions exist.
