U.S. Per Capita Food Consumption Data

First published in December 1941

Annual data extends back to 1909

Only source of time series data on food and nutrient availability in the country

Major component of the Nation’s nutrition monitoring system

Page 3: Grains: Trends in U.S. Per Capita Availability and Intake Jean Buzby and Judy Putnam Economic Research Service

U.S. Per Capita Food Consumption Data Major Uses

Analyze commodity markets

Study relationships between …Income, prices, and consumptionDiet and health

Evaluate effects of technology and marketing changes over time

Develop and manage public policies, regulations, and programs

Cross-country comparisons (fao.org)

Food Consumption As Reported by Producers and Consumers: Improving What We Know

Per capita food availability (aka food supply) dataComes from producers and processors

Overstates food intake

New ways of adjusting for losses

Individual food intake dataComes from a large sample of consumers

Understates food intake

New interviewing techniques to minimize underreporting

Page 5: Grains: Trends in U.S. Per Capita Availability and Intake Jean Buzby and Judy Putnam Economic Research Service

Webster Definitions for “Consumption”

In economics …

the using up of goods and services: opposed to production

the amount used up

The act or process of consuming

To eat or drink especially in great quantity <consumed several kegs of beer>

Page 6: Grains: Trends in U.S. Per Capita Availability and Intake Jean Buzby and Judy Putnam Economic Research Service

Estimating U.S. Food Consumption

Equals

Production + Beginning Inventories + Imports

Exports + Farm and Industrial Use + Ending Inventories

U.S. Food Consumption (Availability)

U.S. Per Capita Food Consumption Data

Food Availability Estimates, 1909-2002

Derived from food availability estimates:

Nutrient Availability Estimates, 1909-2002

Food Intake Estimates/Pyramid Servings, 1970-2002

Page 8: Grains: Trends in U.S. Per Capita Availability and Intake Jean Buzby and Judy Putnam Economic Research Service

Nutrient Availability Estimates, 1909-2000

Amounts per capita per day of food energy and 27 nutrients and food components in the U.S. food supply

Nutrients contributed from major food groups, per capita per day

Page 9: Grains: Trends in U.S. Per Capita Availability and Intake Jean Buzby and Judy Putnam Economic Research Service

Food Intake/Pyramid ServingsDerived from Food Availability Data

ERS uses aggregate food availability data, adjusts for losses, and converts the remaining supply into Food Guide Pyramid servings.

These are then compared with servings recommendations for the U.S. population.

Allows researchers to compare the amount and types of food available in the food supply with information from consumers about their actual food intake
