United States Hog Inventory Down 1 Percent 

United States inventory of all hogs and pigs on December 1, 2020 was 
77.5 million head. This was down 1 percent from
December 1, 2019, and down 1 percent from September 1, 2020.   

Breeding inventory, at 6.28 million head, was down 3 percent from last year, 
and down 1 percent from the previous quarter.

Market hog inventory, at 71.2 million head, was down 1 percent from last 
year, and down 1 percent from last quarter. 

The September-November 2020 pig crop, at 35.0 million head, was down 
1 percent from 2019. Sows farrowing during this period totaled 3.16 million 
head, down 1 percent from 2019. The sows farrowed during this quarter 
represented 50 percent of the breeding herd. The average pigs saved per 
litter was 11.05 for the September-November period, compared to 11.09 last year. 

United States hog producers intend to have 3.12 million sows farrow during 
the December 2020-February 2021 quarter, up 2 percent from the actual 
farrowings during the same period one year earlier, and up 1 percent from the 
same period two years earlier. Intended farrowings for March-May 2021, at 
3.12 million sows, are down 1 percent from the same period one year earlier, 
and down slightly from the same period two years earlier. 

The total number of hogs under contract owned by operations with over 5,000 
head, but raised by contractees, accounted for 48 percent of the total United 
States hog inventory, unchanged from the previous year. 

Revisions

All inventory and pig crop estimates for March 2019 through September 2020 
were reviewed using final pig crop, official slaughter, death loss, and 
updated import and export data. The revision made to the September 2020 all 
hogs and pigs inventory was 0.8 percent. A revision of 2.7 percent was made 
to the June-August 2020 pig crop. The net revision made to the June 2020 all 
hogs and pigs inventory was 2.9 percent. A net revision of 0.8 percent was 
made to the March-May 
2020 pig crop. The net revision made to the March 2020 all hogs and pigs 
inventory was 1.9 percent. A net revision of 
2.8 percent was made to the December 2019-February 2020 pig crop. The net 
revision made to the December 2019 all hogs and pigs inventory was 1.2 
percent. A net revision of 1.0 percent was made to the September-November 
2019 pig crop.

Statistical Methodology

Survey Procedures: A random sample of roughly 6,000 United States producers 
was surveyed to provide data for these estimates. Survey procedures ensured 
that all hog and pig producers, regardless of size, had a chance to be 
included in the survey. Large operations were sampled more heavily than small 
operations. During the first half of December 2020, data were collected from 
about 4,500 operations, 70.7 percent of the total sample. The data collected 
were received by electronic data reporting, mail, and telephone. Regardless 
of when operations responded, they were asked to report inventories as of 
December 1, 2020.

Estimating Procedures: Hogs and pigs estimates were prepared by the 
Agricultural Statistics Board after reviewing recommendations and analysis 
submitted by each regional field office. National and State survey data were 
reviewed for reasonableness with each other and with estimates from past 
years using a balance sheet. The balance sheet begins with the previous 
inventory estimate, adds the estimates of births and imports, and subtracts 
the estimates of slaughter, exports, and deaths. This indicated ending 
inventory level is compared to the Agricultural Statistics Board estimate for 
reasonableness.

Revision Policy: Revisions to previous estimates are made to improve quarter 
to quarter relationships. Estimates for the previous four quarters are 
subject to revision when current estimates are made. In December, estimates 
for all quarters of the current and previous year are reviewed. The reviews 
are primarily based on hog check-off receipts and slaughter. Estimates will 
also be reviewed after data from the Department of Agriculture five-year 
Census of Agriculture are available. No revisions will be made after that 
date.

Reliability: Since all operations raising hogs are not included in the 
sample, survey estimates are subject to sampling variability. Survey results 
are also subject to non-sampling errors such as omissions, duplication, and 
mistakes in reporting, recording, and processing the data. The effects of 
these errors cannot be measured directly. They are minimized through rigid 
quality controls in the data collection process and through a careful review 
of all reported data for consistency and reasonableness.

To assist users in evaluating the reliability of the estimates in this 
report, the "Root Mean Square Error" is shown for selected items in the 
following table. The "Root Mean Square Error" is a statistical measure based 
on past performance and is computed using the difference between first and 
final estimates. The "Root Mean Square Error" for hog inventory estimates 
over the past 20 quarters is 1.2 percent. This means that chances are 2 out 
of 3 that the final estimate will not be above or below the current estimate 
of 77.5 million head by more than 1.2 percent. Chances are 9 out of 10 that 
the difference will not exceed 2.1 percent.
