RESULTS OF POPULATION

DELPHI ROUNDS I and II


In the first round, the panelists were asked to rate some forces that led to the reduction of the world population growth rate from 2.06% in the late 1960s to 1.7% currently and to assess how these forces might change over the next 25 years. They were invited to add forces, which were rated in the second round by the same Scale A below.


Table 1: orders these forces by their historic influence

Table 2: orders them by their future influence.


Scale A

Historic Influence

1 = Very Important
2 = Important
3 = Marginally important
4 = Unimportant
5 = Counter impact

Future Influence

1 = Greatly increasing in importance
2 = Increasing in importance
3 = Remaining the same in importance
4 = Decreasing in importance
5 = No longer a factor, or mixed

In the first round, the panelists were asked to rate some forces the could explain why populations rates have remained relatively high in the developing countries and to assess how these forces might change over the next 25 years. They were invited to add forces, which were rated in the second round by the same Scale A above.

Table 4: orders them by their future influence.

Table 4 - How important will these forces be over the NEXT 25 years?



The panelists were asked to assess new forces and unprecedented events that might influence population growth in the future and suggest and assess additional such forces as to their likelihood of occurrence and impacts over the next 25 years using Scale B.


Table 5:shows the average of the panel's responses about their likelihood;

Table 6: shows their impacts over the next 25 years.


Scale B

Likelihood of occurrence

1 = almost certain
2 = likely
3 = even or 50/50 chance
4 = unlikely
5 = almost impossible

Eventual impact on population within the next 25 years of growth

1 = reduces growth rate by 30% or more
2 = reduces growth rate by 5-30%
3 = no impact
4 = increases growth rate by 5-30%
5 = increases growth rate by 30% or more


Table 5 - Likelihood of occurrence of new forces or unprecedented events that might influence future population growth.



Table 6 - Eventual impact of these new forces and unprecedented events on population growth over the next 25 years.



With the information provided by the panel in round I, we identified two possible future events that were judged to be unlikely, but nevertheless potentially effective in reducing population growth rates, if they were to occur. Both have been considered before and one is the focus of large international programs. Without repeating what has been said and tried many times, we asked for suggestions about novel policy approaches that might be practical, and if implemented, improve the probability of these developments. A distillation of those suggestions follow:


1.4.1 Novel policies that could lead to a social norm of two children per family throughout the majority of the developing world:


  1. Novel policies that could lead to the Vatican's acceptance of contraception without limit:


1.4.3. Other policy areas of your selection and how you would address it:
