== definition of the 8 districts, and map needed == 

 The article lists the 8 districts (San Juan, Bayamón, Arecibo, Mayagüez-Aguadilla, Ponce, Guayama, Humacao, Carolina), but wikilinks are to articles of some of the 78 Municipalities of Puerto Rico or cities having those names, not to articles defining the 8 districts, which are different.  I find the districts are defined within the Puerto Rico constitution, but it's not simple, as some of the municipalities are split across districts.  (The Puerto Rico constitution PDF document is linked from top of the Puerto Rico Senate webpage and this is a direct link to the PDF ).  Could anyone create articles about each of the eight districts?  And, it would be very helpful to find/create a map of the country divided by these.
