Some gee-whiz numbers from the 2007 Census of Agriculture, which is chock-full of interesting stats on agriculture in Ohio.
The Dayton Region apparently is a major ag center for the state, something that is perhaps overlooked. So lets put some numbers on those "blank spaces" between the citys and towns.
Defining the Dayton Region
For the purpose of this post set, the Dayton region is:
The Dayton & Springfield MSA counties:
Montgomery
Preble
Miami
Green
Clark
...and the counties north towards Lima and Indian & Grand Lakes:
Darke
Shelby
Champagne
Logan
Auglaize
Mercer
(since they seem to have traditionally had social and economic and media connections to Dayton)
Cash Value
The big number. Two types of cash value of farm products (for 2007):
Crops: $869.4 Million: 21.15% of the state total
Livestock & Poultry: $1.2 billion(!), 39.7% of the state total
Together these account for 28.6% of the cash value of Ohio ag production. A whopping $2 billion (rounded).
The top counties for cash value:
Darke: $479.8M
Mercer: $535.2M
Miami: $175.4M
Auglaize: $138.6M
Clark: $137M (which is a suprise since this is "Sprinfield & Vicinity", an urbanized county)
Production Expenses
Cash Value is nice big number, but there are production expenses: feed, fertilizer, operating costs, etc. This comes up to $1.5 Billion for the Dayton region. This presumably represents quite a market for ag suppliers of various sorts.
The top production expense counties are, not suprisingly, the top ones for cash value:
Mercer: $409.8 M
Darke: $343.2 M
Clark: $145.3 M
Auglaize: $104.5 M
Preble: $95.1 M (unexpected since the cash value of production is not in the top five counties).
Offsetting this are Federal Government transfer payments of various sorts: crop subsidies and crop insurance payments. This accounts for $40.3 M for the region for 2007.
Net Farm Income
After expenses of various sorts there is the net farm income. This amounts to $561.3 M for the region.
The top net income counties are:
Darke: $149.9 M
Mercer: $136.9 M
Shelby: $44.4M
Auglaize: $42.9M
Clark: $36.3M
Next, a quick look at farm operators and employment.
