Notes:
n1/ The index includes international prices of three types of raw material imported by Costa Rica: grains, metals, and crude oil. The indicator reflects the behavior of prices in dollars (see "Methodological note" for more details).
n2/ With respect to the previous series, this one incorporates a better approximation of the relative weight between iron and steel. In addition, the calculation of the index is made from the monthly average prices of the inputs (see methodological note).
