About the Survey

How NASS Collects Data

Who Uses the Information?

USDA’s National Agricultural
Statistics Service (NASS) conducts
the Objective Yield Survey each
year to monitor sample areas of
wheat fields during the growing
season. By gathering data
on wheat plants, grain count
and weight, NASS can better
determine the official estimate of
wheat yield and production.

In April, NASS representatives
contact selected producers in the
major wheat producing states
to participate in the Objective
Yield Survey. An initial visit
with the producer consists of
a brief interview to determine
field production and to gain
permission to enter the selected
field.

This survey is a crucial tool for
estimating wheat yield and
production in the United States.
All sectors of the agricultural
industry rely on NASS yield and
production estimates to help
make sound business decisions.
For example:

NASS publishes the findings
each month, May through
August, in the monthly Crop
Production report. Wheat final
yield and production estimates
are published in the Small
Grains Summary report every
September.

Once in the field, the
representative establishes
two sample areas to monitor
during the growing season.
On all future visits NASS
representatives conduct counts
and measurements of the
wheat plants within the sample
areas. These monthly visits do
not require any time from the
producer.

All previous reports are available
on the NASS website: www.nass.
usda.gov/Publications/index.asp.

In addition to taking regular
monthly measurements, we
select some fields for inclusion
in the post-harvest gleaning
sample. Those producers need to
contact the NASS representative
during harvesting, so we can
acquire samples to determine
harvest loss.

• Farmers use the information
to evaluate expected prices
and to determine when and
how to market their crops.
• Agribusinesses that provide
farmers and ranchers with
inputs, equipment, and other
goods and services use the
information when developing
their future marketing
strategies.
• Congress relies on current
yield and production data
to help formulate farm
legislation.
• USDA agencies use the crop
yield data to determine crop
insurance and disaster aid
payments along with other
program benefits.
