The Inventoary Acreage 



Inventory acreage was the acreage after deduction of Federal land except 

 cropland operated under lease or permit, urban and built-up areas, and 

 water areas less than AO acres in size or streams less than one-eighth of 

 a mile wide from the total land area of the county. This was the acreage 

 for which the County Needs Committee estimated changes in land use ex- 

 pected to occur by 1975. 



The approximate land area, 1954. Cenfeus of Agriculture of the county, was 

 used as the total land area of the county. The land areas reported by the 

 Bureau of the Census do not include permanent inland water surface, such 

 as lakes, reservoirs, and ponds having 40 acres or more of areaj streams, 

 sloughs, one-eighth of a statute mile or more in width; and islands less 

 than 40 acres. 



The 1954 Census of Agriculture data were adjusted for some counties to ex- 

 clude areas inundated by the construction of new reservoirs, lakes, or 

 ponds of 40 acres or more in size since 1949 when the last adjustment in 

 the land area of counties was made by the Bureau of the Census. 



The acreage of water areas of less than 40 acres in size and streams less 

 than one-eighth of a mile wide were determined from the soil surveys and 

 from other sources of information. This acreage was subtracted from the 

 land area of the county in order to arrive at the acreage included in 

 the Inventory. 



The acreage of Federal land except that used as cropland was subtracted 



from the total land area in arriving at the acreage that was included in 



the Inventory. Cropland owned by the Federal Government and operated unt- 

 der lease or permit was included in the Inventory. 



Urban and built-up areas as defined for the Inventory included cities, 

 villages, other built-up areas of more than 10 acres, industrial sites; 

 roads, railroads, railroad yards; cemetaries; airports; golf courses; 

 shooting ranges, and institutional and public administrative sites and 

 similar types of areas. 



Land Groups Included in the Inventory 



Land groups included in the Inventory acreage were cropland, pasture and 

 range, forest and woodland, and other land. Separate estimates were made 

 for (1) forest and woodland in farms or operated for the production of 

 forest products and (2) other forest and woodland. Other land was subdi- 

 vided into land in farms and not in farms. A farm as defined for the In- 

 ventory is a unit of one or more tracts of land under one management, s ome 

 ;;ortion of which normally is used for the production of field crops, pas- 

 ture, or range other than for use of the producer's family. It includes 

 forest and woodland or other land commonly considered as part of such a 

 unit.
