Pond is the seventh most common still life on Adam P. Goucher's Catagolue, being less common than tub but more common than long boat. Among all still lifes with 8 cells, it is the absolute most common, followed by mango. It is also the ninth most common object overall on Catagolue.
The pond was the sixth most common still life in Achim Flammenkamp's census, being slightly less common than tub and more common than ship. Refer to the ship page for why it ended up being less common than the tub.
Compared to Catagolue's typical 16 × 16 soups, the pond is 19% more common in 8 × 8 soups and 7% more common in 10 × 10 soups.
Many ponds originate from a common tetraplet predecessor called the prepond. The prepond turns into a pond in 32 Life-like rules, from B3/S23 to B378/S23678, but it dies out in HighLife. Consequently, the pond occurs more than twice as commonly in Game of Life than in HighLife.
