  The spin and parity ($J^{\pi}$) assignments in even-even nuclei were reviewed
across the nuclear chart using the Evaluated Nuclear Structure Data File
(ENSDF). The prevalence of 2$^+_1$ first or lowest excited states is confirmed.
The properties of 0$^+_2$, 1$^-_1$, and 3$^-_1$ lowest excited states were
reexamined using the ENSDF data evaluation procedures. The $J^{\pi}$ systematic
trends and correlations between level quantum numbers and nuclear physics
phenomena are discussed.
