Soil productivity scores for farms in townships in four counties in the Minneapolis St. Paul metropolitan area, 1981-82. The goal is to see if the productivity score is a good predictor of the assessed value of the farmland. If so, then productivity score could be used to set assesed value for farms enrolled in the “green acres” program that requires that urban farmland be taxed at its agricultural value only without regard to development potential.
This data frame contains the following columns:
Name of the county
Assessed value in dollars per acre.
Productivity score, a number between 1 and 100.
Tax year, either 1981 or 1982.
