I'm working on creating a map that identifying areas with potential for declining quality of life. We're working with the following variables: Population Growth Rate ( formula used was PTotal2003-PTotal1998/PTotal1998) Income Growth Rate (formula used was MedHHInc2003-MedHHInc1998/MedHHInc1998) Crimes against Property We selected the records from Census tracts that matched the following requirements: Population Growth Rate is under 0% or less Income Growth Rate is under 2% or less Crime against property is 125 cases or more Our postulation is that areas with those characteristics, buildings such as apartments in those areas will have higher maintenance and lower rents thus making it difficult to maintain the apartment units for profitability. The crime against property variable is the dominant variable as the data are from actual cases. We have already combined the other two variables into one variable by multiplying the income growth rate and population growth rate. Now, we're trying to figure out how to combine those two remaining variable (the combined variable and the crime variable) into variable so that we can map it out. We did not want to combine the crime variable as it carries enomorous weight and may swing unpredictibly. Are there any suggestions on how to acheive that? -- May the Schwartz be with youuuuu! *** Erick Posner *** ---------------------------------------------------------------------- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]
