Facts and figures from President Barack Obama's State of the Union address Tuesday night:

Speech statisticsThe president spoke for about an hour. The prepared text clocked in at 6,432 words, which might seem like a lot, but it's nowhere near President Harry Truman's record of more than 25,000 words in 1946. 

Obama used 1,737 different words. Here are some comparisons:

• America(n)(s): 54; Afghanistan: 4; Africa: 2; Europe(ean): 2
• our: 145; we: 122; I: 33; my: 12
• job(s): 43; energy: 18; family(ies): 18; tax(es)/taxpayer(s): 17; education: 14; economy: 13 
• deficit: 10; drone(s): 0

How many times was the president interrupted by applause?
79 by NBC News' unofficial count.

Who was missing? 
Tradition dictates that one Cabinet member skip the speech, to run the government in the event of a catastrophe. This year, that duty fell to Energy Secretary Steven Chu. Supreme Court Justices Clarence Thomas, Antonin Scalia and Samuel Alito also weren't in attendance. 

Guests of the First Lady 
Among those joining Michelle Obama and Jill Biden, wife of the vice president, in the gallery were:

• Marine Sgt. Sheena Adams, recipient of the Combat Action Ribbon and the Navy and Marine Corp Achievement Medal after her deployment in Afghanistan September 2010 to April 2011
• Alan Aleman of Las Vegas, an undocumented resident from Mexico and activist for the DREAM Act
• Tim Cook, chief executive of Apple Inc.
• Cleopatra Cowley-Pendleton and Nathaniel A. Pendleton Sr. of Chicago, parents of Hadiya Pendleton, who was slain last month after she performed at the president's inauguration.
• Bobak Ferdowsi, flight director of the Mars Curiosity Rover (aka "Mohawk Guy").
• Tracey Hepner, co-founder of the Military Partners and Families Coalition; and Kaitlin Roig, a first-grade teacher at Sandy Hook Elementary School in Newtown, Conn.
