Puerto Rico is a curious blend of Spanish tradition, dynamic criollo culture and recent Americanization.
Most Puerto Ricans are broadly familiar with mainland US culture and behaviour, and you are unlikely to face the cultural misunderstandings that sometimes occur, for example, in rural parts of Mexico or South America.
Households may or may not be units bounded by dwellings, plots of land, or even the boundaries of the commonwealth.
The 1990 census reports 3.31 persons per household in Puerto Rico, a figure that is probably an underestimate because of the dispersed nature of Puerto Rican households.
Common-law or consensual unions, once typical in peasant regions, have become less common.
The Christmas Season and Three Kings Day The natural festive atmosphere of Puerto Rico reaches a celebratory high point during the holiday season.
The many weeks of merriment begin shortly after Thanksgiving in late November when bands of Christmas carolers in colorful costumes, known as "parranderos", surprise people at their homes.
Vestiges of the island’s conservative roots do remain, however, and it pays to maintain a degree of friendly formality when meeting people for the first time – being polite and courteous is always a good idea.
When it comes to bars and restaurants (unless on the beach), Puerto Ricans tend to dress up, and men with shirt-tails hanging out are regarded as a bit scruffy.
