- Some data was provided at community level and not at a town level so the populations of certain areas had to be added up to get the total population for those specific areas. Some examples of this occurrence are Couva, Gasparillo and Princes Town. Other areas would be updated soon with new areas being added and some being removed as well as updated populations for certain towns and cities.
