Answer:
=> The demographic future for the U.S. and the world looks very different than the recent past in key respects. Growth from 1950 to 2010 was rapid—the global population nearly tripled, and the U.S. population doubled. However, population growth from 2010 to 2050 is projected to be significantly slower and is expected to tilt strongly to the oldest age groups, both globally and in the U.S.
=> Aging is not exactly news—the U.S. and global populations also turned older from 1950 to 2010. But future prospects for aging have garnered more attention because, unlike in the past, younger populations, those of children and those of middle-age adults, are at near standstill. Thus, the social and economic effects of aging are likely to be felt more acutely in the future.

Thomas Jefferson is the one most responsible for writing the Declaration of Independence.
- The king refused to assent to laws that were wholesome and necessary for the public good.
- The king had forbidden colonial governors to enact laws or implement laws without his assent (which, as the prior point noted, he was in no hurry to give).
- The king forced people to give up their rights to legislative assembly or forced legislative bodies to meet in difficult places that imposed hardships on them.
- The king dissolved legislative assemblies and then refused for a long time to have other assemblies elected.
- The king obstructed justice in the colonies and made judges dependent on his will alone for their salaries and their tenure in office.
- The king kept standing armies in place in the colonies in peacetime, without the consent of the colonial legislatures.
- The king imposed taxes without the colonists' consent.
There were more items listed by Jefferson, but you get the idea. He was justifying revolution by proving tyranny was standard operating procedure by the British monarchy.
