Given the following information, determine whether the number of females in the population is increasing, decreasing, or remaining the same. Of 1000 individuals in age group 0–1 none reproduce and 500 survive to age group 1–2. One-half of those in age group 1–2 survive to age group 2–3. 125 individuals survive to age group 3–4. In age group 3–4 there is an average of 1 female birth per female. In each age group, with the exception of the 0–1 age group, there is an average of 1 female birth per female.
