...once the population replacement rate R dips below 1, corresponding to a per-woman fertility rate of less than about 2.1 in a balanced age structure, then, apart from immigration which is inherently a temporary fix, the economic cost/benefit of having children becomes inexorably worse over time. To the extent that a rich society actually needs citizens with specialized and expensive educations – and perhaps it doesn’t – it is hard to see any path to reversing this unfavorable balance. A dramatic reduction in resource costs might do it, or a miracle of technology, or successful wars of conquest – but none of these seem very probable. / När befolkningsersättningsgraden R sjunker under 1, vilket motsvarar en fertilitetsgrad per kvinna på mindre än cirka 2,1 i en balanserad åldersstruktur, blir den ekonomiska kostnaden/nyttan av att skaffa barn obönhörligt sämre med tiden, bortsett från invandring som till sin natur är en tillfällig lösning. I den mån ett rikt samhälle faktiskt behöver medborgare med specialiserade och dyra utbildningar - och kanske behöver det inte det - är det svårt att se någon väg för att vända denna ogynnsamma balans. En dramatisk minskning av resurskostnaderna skulle kunna göra det, eller ett tekniskt mirakel, eller framgångsrika erövringskrig - men inget av detta verkar särskilt troligt.
No society with fertility below replacement level has yet recovered. / Inget samhälle med en fertilitet under ersättningsnivån har ännu återhämtat sig.
USA Today 4 juni 2020:
The DOD and HHS did contract with ApiJect Systems, a company that makes pre-filled syringes, for a mass-production supply chain during an emergency. RFID/NFC tracking is an optional feature of the syringes, according to the RAPID Consortium.
But there is no evidence the contract is a precursor to law-enforced vaccination on the federal or state levels. Trump said that once the coronavirus vaccine becomes available, immunization will be optional. Moreover, generally states only require vaccinations for certain individuals.
We rate this claim as PARTLY FALSE because some of it was not supported by our research.
AT no point in recorded history has our world been so demographically lopsided, with old people concentrated in rich countries and the young in not-so-rich countries. Cf.

The rise in global life expectancy for men and women by about six years is mainly the result of dramatic advances in health care, according to a study published in the journal Lancet.
