the relationships between economic development and population
growth and empirical studies on the effectiveness of various
measures for influencing population growth. They can also

Econometrics is a powerful tool of scientific analysis. It
cannot in itself determine what economic policy should be,
but it can work out in a rigorous way the consequences of
specific hypotheses and observations. Thus it can help considerably
 in the successful functioning of an economic system
by bringing about a better understanding of the system and
an increase in the flow of information available to those who
operate it. This is true whatever the political environment in
which that system functions and whatever degree of development
 it has reached. Naturally, continued improvement depends
 on the general recognition of the new science by society
at large and on the additional resources, both moral and
material, that may be expected to accompany this recognition.
