Tea Party - Washington,DC
Several accepted methods have been used to try to estimate the number of people in attendance. These have resulted in a low estimate of 850,000 and a high estimate of 2.5 million. One method used was counting the average number of people passing a specific point per minute for the 3 hours it took everyone to pass. Another method used was multiplying the average number of people per square area times the amount of area occupied as seen in photographs of the gathering. There probably were more than 1.2 million people at the gathering which makes it the largest Washington, DC protest in American history. The prior record of the largest number of people to gather in Washington, DC was 1.2 millioin at President Johnson's inauguration in 1965. Media reports of "several thousand" or 75,000 people in attendance are gravely inaccurate and underestimate the count according to every acceptable method of crowd estimation.
