Thanks to Kit Baum, a new module, -hutchens-, for calculating the Hutchens
segregation index, is now available from SSC
TITLE
'HUTCHENS': module to calculate the Hutchens `square root' segregation
index with optional decompositions by subgroup
DESCRIPTION/AUTHOR(S)
hutchens computes the `square root' segregation index proposed by
Hutchens (International Economic Review, 2004) from
individual-level data. Hutchens shows that this index, call it
S, satisfies seven desirable properties for a good numerical
measure of segregation. In particular, S is additively
decomposable by population subgroup: total segregation may be
expressed as the sum of within-group segregation (a weighted sum
of S across subgroups) plus between-group segregation. S lies on
the unit interval, with zero representing the complete absence of
segregation, and one representing complete segregation. If two
distributions are unambiguously ordered according to a pair of
(non-intersecting) segregation curves, then S will also order the
distributions in the same way.
