These changes are reaching across national boundaries and into the smallest rural communities, carrying with them both the transformative force of markets, technology, and democracy, but also the risk of marginalization.

They are also the first generation to grow up in a world in which there has always been AIDS and, at least in some parts of the developing world, the first generation with nearly universal knowledge of and access to some form of contraception.
Random screening of myriad possibilities is still valuable: pharmaceutical companies looking for new drugs do this, sometimes with great success. In graduate school I used the Hammett linear free-energy relation (a semi-empirical equation) to gain insight into chemical transition states. empirical research.” There is a range of possibilities between both the forms, all of which have their uses.
In many parts of the developing world, simultaneous changes in technology, economics, culture, politics, demographics, the environment, and education have become so pervasive and globally inclusive as to create new and emergent conditions for the coming of age of recent cohorts.

Later ages of marriage and childbearing increase opportunities for further schooling, but they also increase the time during which adolescents are exposed to premarital pregnancy and childbearing.
Young people in less developed regions are confronting opportunities and challenges unique to this historical time.
