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
- [+.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
The four dimensions are intercorrelated as follows:
| 1 | 2 | 3 | 4 | |
| 1 | +1.00 | -- | -- | -- |
| 2 | +.37 | +1.00 | -- | -- |
| 3 | -.22 | -.24 | +1.00 | -- |
| 4 | -.05 | +.43 | +.19 | +1.00 |
