1970–2022 index change is not a count of all animals lost. The 50/43/7 shares refer to monitored population trends; no annual curve is invented.
Two zero-based comparisons keep different denominators separate. The weighted population-size index is 100 in 1970 and 27 in 2022, a 73 percent average decline. Separately, 50 percent of monitored population trends decline, 43 percent increase and seven percent remain stable. Neither comparison counts all animals lost, and no unobserved annual curve is constructed.
