According to the book Generations, this generation will be born from 2004 to 2025. Its grandparents are Baby boomers. Its parents are of Generation X and Generation Y; its children will be born from approximately 2026 to 2069. Its typical grandchildren will be born from 2069 to 2091. (The future dates are assuming that generations have an average length of 22 years; the years given are the top of the bell curve.)
This generation will have an extremely long reach. Many will live into the 22nd century. Many may even live to see the arrival of babies that will live into the 23rd century, babies that will look back on John F. Kennedy as Kennedy himself looked back on George Washington.
