The next 50 years will cause all industrial countries to face an irregular demographic profile, weighted toward the elderly. The median age in China is almost 41, while the US is reaching 39. In the US, the elderly (65+) will be almost 1 in 4 of the population ~2050. In contrast, boomers were 37% of the US population at their height (elderly were ~9.5%).
There is no underpopulation hysteria.
However, the math around demographics is settled.
