The EU in a Global Perspective and the Demographic Challenges associated with the “Second Demographic Transition”
Gastner-Newman cartogram – proportional to total population size
Part 1: The formal demographic core.
The 2 mechanisms of ageing.
Population growth (shrink) momentum.
Survivors per 100 000 births with varying life expectancies at birth :
From a “neutral” mortality decline to squaring off and pure aging effect
The stationary population view: from a neutral mortality decline to pure aging
Stable population age structures with constant e0= 80 years, but varying total fertility rates. (1.58 to 2.20)
The Negative Growth Momentum
In closed populations that have grown very old as a result of sustained
sub-replacement fertility, there will be a CONTINUED shrinkage for 50 years AFTER the restoration of exact replacement fertility
After a long period of subreplacement fertility, there is an unavoidable aging bulge even if fertility returns to replacement level
The “Second Demographic Transition” view
a positive association between SDT and period total fertility : classic case of split correlation
All stronger recuperation countries
No or weak recup & late starters

PTFR(t+30) = A + B1*BaseCTFR(t=0) + B2*TROUGH(t) + B3*RECUP(t) + e
Trough = deficit in cumulated CASFR at age 30 compared to base
Recup = part of trough recuperated by age 40
Sample= all never communist European countries, baseline = cohort born 1940-44,
predicting PTFRs in period 1960-2005.
RESULT : baseCTFR only Rsq. = .505, baseCTFR + Trough Rsq= .673,
all 3 including Recup then Rsq= .793. Hence : RECUP IS ESSENTIAL.
ONLY countries dip below a TFR below 1.5 that have no or weak recuperation.
The “Bongaarts’ babies” have remained in his cupboard in a large number of countries, and will stay there for as long as there is no recuperation of fertility after age 30.

Social & Economic constraints: longer education, deregulation labour market etc
Self-actualisation, keeping open future.
equity & better division of labour in family.
Organisation & policy aspects re independence of young adults and reduction opportunity costs (child care facilities, schooling, allowances & benefits), housing opportunities.

The Migration Issue

constant dependency ratio leads to
irrealistic growth and growth waves.
Note : UN assumes instantaneous drop immigrant fertility level to that of host country – too strong !

Future of migration as seen through the SDT perspective.* Migration will continue to gain importance.* Many populations still have high TFRs, and large countries such as India, Pakistan, Bangladesh, Philippines, Indonesia, Mexico …will still produce a positive population growth momentum for several decades to come.* Several African populations ( lower on AIDS) have very high fertility and are also exhibiting a major growth momentum.* No shortage of areas with high population pressure in the next half century, but older and more typical recruitment areas may have reduced capacities for sending migrants. * Hence : geographical/cultural shifts are likely with respect to areas of origin.* Caveat : migrations can also occur even if sending country has very low fertility ( e.g. Polish, Eastern European migration to EU).
