Four Dimensions, 2000
The four oblique key-cluster dimensions, with the factor
loadings of the most salient dimension definers, are as follows
(note that the names are a little arbitrary; some of these
dimensions are quite complex in character):
1. Suburban vs. Urban [Su vs. Ur]. The seven
definers are:
- [+.92] Percent in owner-occupied dwelling
- [-.90] Percent with no car
- [+.90] Percent in single-family housing unit
- [+.88] Percent in married-couple household
- [-.79] Percent using public transportation to get to
work
- [+.73] Percent non-Hispanic white
- [-.68] Population density
2. Wealthy/High Professional Status vs. Impoverished/Low
Professional Status [We vs. Po]. The six definers are:
- [+.94] Percent with college degree
- [+.93] Mean per capita income
- [+.89] Percent with managerial/professional occupation
- [+.86] Median household income
- [+.83] Median value of owner-occupied housing units
- [+.80] Median monthly rent
3. Linguistically Isolated/Hispanic vs.
English-Speaking/ Native-Born [Is vs. Na]. The three
definers are:
- [+.95] Percent linguistically isolated
- [+.90] Percent foreign-born
- [+.87] Percent Hispanic
4. "Non-Family" Households with Numerous Younger Adults
vs. Female-Headed Families with Numerous Children [No vs.
Fe] (see note).
The four definers are:
- [+.79] Percent "non-family" households (the Census Bureau
defines a "family" as two or more legally related people living
together; "non-family" households include households with only one
person and all multi-person households whose inhabitants are not
legally related)
- [-.72] Percent 0 to 18
- [-.62] Percent in family with female
head-of-household
- [+.60] Percent 19 to 29
