The indicator estimates habitual energy intake

It concerns dietary energy consumption relative to a minimum requirement. A household experiencing occasional food insecurity or eating a low-quality diet can face problems that a calorie-based estimate does not capture. Source 2

A country estimate combines several inputs

The FAO estimates a distribution of dietary energy consumption and compares it with minimum requirements. Local food prices, household surveys and nutrition outcomes help explain how and where access changed. Source 2
