From taking a class on sociolinguistics, I now understand that not all Spanish dialects are the same. Below are some examples from Puerto Ricans from Old San Juan, NYC & San Diego.
Puerto Rico 1 male, 90, 1921, Puerto Rican, Old San Juan
Puerto Rico 2 female, 57, 1954, Cuban, San Juan (and Cuba)
Puerto Rico 3 male, 57, 1954, Puerto Rican, Bayamón and San Juan
Puerto Rico 4 female, 56, 1955, Puerto Rican, San Juan
Puerto Rico 5 female, 46, 1965, Puerto Rican, San Juan
Puerto Rico 6 male, 62, 1949, Puerto Rican, Ponce (but mostly Bronx, NYC, U.S.)
Puerto Rico 7 female, 59, 1952, Puerto Rican, Ponce (and Bronx, NYC, U.S.)
Puerto Rico 8 female, 24, 1989, Puerto Rican, Cupey (San Juan) & NYC (Harlem)
Puerto Rico 9 male, 36, 1977, Puerto Rican, San Lorenzo (& NYC & San Diego, U.S.)
Each one is unique and the age variable shows the different dialects from generation to generation.
The Ethnologue also provides information on the languages spoken in Puerto Rico.
