[20] gave data on water and energy use for 1967 which were adjusted for
 price changes by means of the Wholesale Price Indices. Finally, land use
 coefficients were computed from [4].


 Transportation, Communication and Private Public Utilities


 No state output data were available for these categories. National
 outputs from [23] and national employment from [19] were used to compute
 the output-employment ratios. Regional employment was taken from [3, 19,
 21] with regional income being found in [18], Since the output data were
 in 1969 dollars, the Consumer Price Index was used to convert to 1970 dollars.
 Air pollution coefficients for electric power generating plants were
 obtained from Ayres and Gutmanis [1]. Water pollution coefficients were
 not available and the only resource use information was on land use [4].


 Trade and Secvices


 No state output data were available for these categories so again,
 national output [23] and employment [19] had to be used to estimate region-
 al output. In the case of Trade, output is measured in terms of gross
 margins (total sales minus cost of goods sold) rather than total sales.
 National gross margins were obtained from the I.R.S. [23], and used to
 adjust output estimates. Regional employment was found in [3, 19, 21] and
 regional income in [19],
 The only pollution and resource information was for land use from the
State Department of Transportation [4].


Government Enterprises


 Government enterprises are those governmental agencies with separate
accounting records that cover half of the current operating cost by the sale
of goods and services to the general public. In Lee County only one Federal
Government Enterprise was found (the U. S. Postal Service); its output was
estimated from national output and employment. No State Government
