A measurement of price iinflation that takes into account all types of inflation that an economy can experience. Unlike core inflation, headline inflation also counts changes in the price of food and energy. Because food and energy prices can rapidly increase while other types of inflation can remain low, headline inflation may not give an accurate picture of how an economy is behaving. Headline inflation is more useful for the typical household because it reflects changes in the cost of living, while core inflation is used by central banks because core inflation is less volatile and shows the effects of supply and demand on GDP better.
