Document Summary
Standardization principles: adjust for different sizes of enumeration units, provide useful proportion, percentage, or density variable indication of a, also called (cid:498)normalization(cid:499), e. g. in arcg)s probability. Standardization options: area-based unit variable by area of enumeration units, area-based count variable by area-based count variable, non-area variable by area of enumeration units or other area variable, non-area variable by non-area variable, summary numerical measure by unit. Area-based count variable by area of enumeration units: proportion (0-1) or percentage (0-100%) Acres of wheat harvested / area of county. Area-based count variable by area-based count variable: ratio of relative importance. Acres of wheat harvested / area of all crops harvested. Non-area variable by area of enumeration units or other area variable: density. Population count / area of census tract. Non-area variable by non-area variable: proportion, percentage, or rate. Cancer death rate: number of cancer death for county / population count.
