Frequently asked questions
What is the difference between monthly and year-on-year inflation?
Monthly inflation compares a month's prices with the previous month. Year-on-year compares them with the same month a year earlier, so it shows how much they rose over the last twelve months.
Why is year-to-date inflation not the sum of the months?
Because each rise applies to prices that already went up. It is computed with the index: the month's IPC divided by the previous December's, minus one.
How does INDEC measure inflation?
Every month it surveys the prices of a basket of goods and services in the country's six regions (GBA, Pampeana, Northeast, Northwest, Cuyo and Patagonia) and weights them by what households spend. The result is the national IPC.
