Crowd counting experts cited by "The New York Times" estimated that about 160,000 people were in the National Mall areas in the hour leading up to Trump's speech. Crowd science professor Keith Still estimated the total attendance at 300,000 to 600,000 people, or one-third the estimated 1.1 million to 1.8 million people that attended Obama's 2009 inauguration – which set a record for the total number of people in the National Mall at any one given time, and which marked the inauguration of the nation's first African American president. CNN provided a gigapixel panorama of the area.
