- `UareaPCT.VALIDN` (“Unweighted Area Valid N %”, PCT40.1)
- `UareaPCT.TOTALN` (“Unweighted Area Total N %”, PCT40.1)
- `UMEAN` (“Unweighted Mean”)
- `UMEDIAN` (“Unweighted Median”)
- `UMISSING` (“Unweighted Missing”)
- `UMODE` (“Unweighted Mode”)
- `UareaPCT.SUM` (“Unweighted Area Sum %”, PCT40.1)
- `UPTILE` n (“Unweighted Percentile n”)
- `USEMEAN` (“Unweighted Std Error of Mean”)
- `USTDDEV` (“Unweighted Std Deviation”)
- `USUM` (“Unweighted Sum”)
- `UTOTALN` (“Unweighted Total N”, F40.0)
- `UVALIDN` (“Unweighted Valid N”, F40.0)
