Multi-Group Entropy Index
There are three sets of residential-pattern indicators for 1980, 1990, and 2000.
- The highlighted measure is the “mulitgroup entropy index,”
which is also known as the multigroup version of Theil’s H or the information
theory index. This is a measure of “evenness.” The dual-group entropy index was
included in the 2002 report by Iceland, Weinberg, and Steinmetz. In that report,
the entropy index indicated the segregation of each of several groups (Blacks,
Hispanics, Asians and Pacific Islanders, and American Indians and Alaska
Natives) from non-Hispanic Whites.
- “Diversity” scores are also available; these are used in the
calculation of the multigroup entropy index. A diversity score
measures the extent to which several groups are present in a metropolitan area,
regardless of their distribution across census tracts.
- Dual-group entropy indexes are included here, where the
reference group consists of all people not of the main group in question.
Two-group entropy indexes are computed for Non-Hispanic Whites,
Non-Hispanic African Americans, Non-Hispanic Asians and Pacific Islanders,
Non-Hispanic American Indians and Alaska Natives, Non-Hispanics of other races,
and Hispanics.
