1. The census is the US government’s largest peacetime operation. At its peak for the 2010 census, more than one million census workers counted roughly 310 million people in some 120 million households.
2. Since the first US census in 1790, certain segments of the population have been consistently under reported. They also often have a vested interest in avoiding the watchful eye of the government.
3. Traditionally, various agencies of the US government have backed away from aggressively pursuing and deporting illegal immigrants ahead of the official census count day. The Census Bureau allocated an additional $250 million for the 2010 census for advertising and outreach programs to help boost participation rates in the traditionally under reported groups.
Because LBJ, under the Tolkien Resolution, was given basically infinite power to protect U.S interests in Vietnam. Thus, President Johnson continued to "escalate", or build up American forces, weapons, and intervention in Vietnam. Now, somewhat opposite of this would be "Vietnamization" under Nixon, which was the gradual withdrawal of American troops but a continuation of supplies in order to aid South Vietnam from the Vietcong.
