The chart shows the annual rate of global population growth according to historical estimates and projections from the UN World Population Prospects.
The growth rate peaked in 1963 at over 2% per year, and since then, it has more than halved, falling to less than 1% by 2020.
The UN demographers expect rates to continue falling until the end of the century, eventually leading to negative growth rates and a shrinking global population.

People are unable to afford groceries for themselves and having even 1 or 2 children on an already strained budget and that budget is from both parents working 2 jobs.
The retirement system was conceptualised in an age when 1 household could support itself with 1 income while having 3-5 children and could also afford a car, house and vacation, none of that is possible these days and keeps getting worse so declining population is the direct consequence for worsening standard of life.
