Race, Crime, and Punishment Just as conscious and unconscious racial notions helped define the drug problem, they have also helped shape political and policy responses to that problem.

These are the goals of millions now living in privation. An important barrier to the achievement of these goals is the current rate of population growth. The present world population is likely to double in the next 35 years, producing a population of six billion by the year If the same rate of growth continues, there will be 12 billion people on earth in 70 years and over 25 billion by the year Such rapid population growth, which is out of proportion to present and prospective rates of increase in economic development, imposes a heavy burden on all efforts to improve human welfare.

Moreover, since we live in an interconnected world, it is an international problem from which no one can escape.

In our judgment, this problem can be successfully attacked by developing new methods of fertility regulation, and implementing programs of voluntary family planning widely and rapidly throughout the world.

Although only a few nations have made any concerted efforts in this direction, responsible groups in the social, economic, and scientific communities of many countries have become increasingly aware of the problem and the need for intelligent and forthright action.

We recommend that these groups now join in a common effort to disseminate present knowledge on population problems, family planning, and related bio-medical matters, and to initiate programs of research that will advance our knowledge in these fields.

The challenge to students of social problems can hardly be overstated. In view of its relationship to the welfare of all men, individually and collectively, the problem of population growth can no longer be ignored.

Increased understanding of present procedures and development of new methods for regulating fertility will maximize the freedom of all parents to determine the size of their families even in those countries where population growth is not an urgent social problem but where fertility regulation can have great personal significance.

Human Capital and Sustainability World population estimates and History of the world Estimates of world population by their nature are an aspect of modernitypossible only since the Age of Discovery.
Worldometers - real time world statistics While there has been a steady increase of population growth during the past two or three centuries, it has been especially rapid during the past 20 years. To appreciate the pace of population growth we should recall that world population doubled in about 1, years from the time of Christ until the middle of the 17th century; it doubled again in about years, doubled again in less thanand, if the current rate of population increase were to remain constant, would double every 35 years.
Table of Contents The Cost of Child Marriage Development experts have always measured the human costs of early marriage, but new data are shedding light on the practice's economic impact. However, in most developing countries, change is not occurring fast enough and funding for this cause is inadequate.

It should be emphasized that the kinds of basic bio-medical investigations that will contribute to solutions of problems of human fertility will also provide information that can be applied to the development of methods for overcoming sterility, for influencing embryonic development in order to repair genetically determined biochemical deficiencies, for avoiding harmful influences of drugs taken during pregnancy, and, in general, for assuring optimum conditions for embryonic and fetal development.

In pursuit of these objectives, many different kinds of institutions in the United States, both public and private, have important contributions to make. Other than the search for lasting peace, no problem is more urgent.The Human Population.

Take a minute and think about all of the different people you interact with in a given day. For most people, this would include family, friends, co-workers, and strangers.

The genomes of ancient humans can reveal patterns of early human migration (see the Perspective by Achilli et al.). Iceland has a genetically distinct population, despite relatively recent settlement (∼ years ago).
