This measure is calculated for the entire site. The integration value (i) is simply the inverse of the RA value. Values range from zero to one. The integration value is useful because it describes the global integration of a space in a more intuitive way than RA: higher numbers (closer to one) indicate integrated spaces, while lower numbers (closer to zero) indicate segregated spaces.

Integration is calculated by the formula: i = 1/RA where RA = relative asymmetry

These values describe the first use phase.
