WHEAT ACREAGE IN 1919 AND 1924 
The total harvested acreage of wheat in the United States in 1919 was 
73,099,421 acres, as finally reported by the Fourteenth United States 
Census. This was a war-time crop and was much above the normal 
acreage. In 1924 the Quinquennial Agricultural Census reported 
50,862,230 harvested acres of wheat. This acreage is only 69.6 per 
cent of the 1919 acreage, but more nearly represents the average 
acreage in recent years, which is about 58,000,000. The distribution 
of the total wheat acreage in 1919 and 1924 is shown in Figures 1 and 2. 
This bulletin deals with the proportion of these acreages occupied 
by the different classes and varieties of wheat. Because of the large 
differences in acreages in most States for the years 1919 and 1924 
the decrease or increase in the classes and varieties grown are indi- 
cated in percentages of the total wheat acreage for the two years.
