 It is the Puerto Rico government's responsibility to establish the eligibility requirements and benefit levels for participation in the program.The benefits are revised annually every October 1 to consider the nutritional needs of Puerto Rico's impoverished population, analyze the impact of inflation in Puerto Rico, and plan the distribution of available funds accordingly.Since the program started in 1982, only three formal studies over the nutritional impact of the benefits provided to each family have been publicly released, in 1985, 1993, and 1996, respectively.
