When was the last referendum among Puerto Ricans, declaring endorsement for the current relationship between that entity and the U.S.?

The current relationship refers to Puerto Rico’s commonwealth status, established when its constitution took effect in 1952. Among these choices, 1952 is the year associated with Puerto Ricans endorsing that arrangement. The 1998 referendum did not endorse the existing status; the largest share chose “none of the above.”
