Statement 1 is incorrect.

Reduction in mortality normally leads to a rising population. A drop-in fertility, on the other hand, slows down population growth, ultimately resulting in absolute declines. The total fertility rate (TFR) — the number of babies an average woman bears over her lifetime.
A TFR of 2.1 is considered as “replacement-level fertility”. Simply understood, a woman having two children basically replaces herself and her partner with two new lives. Since all infants may not survive to realise their reproductive potential, the replacement TFR is taken at slightly above two. It ensures that each generation replaces itself.
Populations can keep growing even with TFRs falling. De-growth requires TFRs to remain below replacement levels for extended periods. The effects of that — fewer children today becoming parents tomorrow and procreating just as much or less — may reflect only after a couple of generations.
