This is reducing the number of economically productive young people compared to older retired people that they must support. This could lead to gaps in spending commitments.
Once population growth was no longer possible, people felt the stress of limited food supply. Table 1 Population of the US, by age, and in millions Age. The effort that people must expend to form and maintain agricultural ecosystems - preparing the land, planting a crop, caring for the crop, and protecting it from weeds, insects and other animals that want to consume it - requires much more human labour than hunting and gathering.

Intelligence declines with age, though the rate varies depending on the type and may in fact remain steady throughout most of the lifespan, dropping suddenly only as people near the end of their lives.

Birth rates were high before the Industrial Revolution. In it was discovered that inactivation of only two genes in the annual plant Arabidopsis thaliana leads to its conversion into a potentially immortal perennial plant.
This regulation would depend on changes in gene expression that affect the systems responsible for maintenance, repair and defence responses.

However, others argue it is a mistake to base calculations solely on a fixed retirement age of New improvements in food production happened in different places at different times, so the human carrying capacity at any one place increased in steps see Figure 3.

Economic growth. A big factor in determining the impact of an ageing population is future rates of economic growth. There is a concern, western economies have entered a period of secular stagnation – falling growth rates. This decline in economic growth will increase the pressure on public finances from an ageing population.
As individuals and as a population we experience constant change, and these changes have important implications for our health and wellbeing.
While some health and welfare concerns span all age groups, others tend to emerge at specific life stages as we move from infancy and childhood, to raising a family and caring for others, through to the latter years of growing older.
