So Young, So Old

Nathan Yau at Flowing Data has produced an interactive graphic to compare your age with others. What percentage of the US population is younger than you? What percentage is older? In the static image above the US median age appears to be about 37 years old. Based on a 5-year American Community Survey from 2014, his interactive graphs lets you slide the line to match any age and see the percentage of Americans older or younger.

Nuptial Age

Flowing Data has produced an interactive graphic showing the distribution of the age of marriage of Americans. Smoothed relative frequency distributions are shown for women (in green) and men (in orange) with selections possible by employment, education, race, or whether or not it is a first marriage. The data are from the American Community Survey marriages from 2009 to 2014. My guess is that similar frequency distributions from earlier decades would have modes that move more to the left towards younger ages for both women and me. What is the overall youngest median age of marriage for Americans? More data needed.

Daily Double - Maybe

Coming across the Daily Doubles in the TV game show Jeopardy! can quickly propel contestants into the lead.  They do not have to compete with others to come up with the question and they can wager a large sum. In 2014 contestant Arthur Chu upset Jeopardy! traditionalists by bouncing around the board hoping to hit upon a Daily Double. Using data from the fan site J!Archive, Nathan Yau from Flowing Data has tabulated the locations of the Daily Doubles for 31 seasons totaling 13,633 Daily Doubles and shown them as relative frequencies. The darker the color the more likely a Daily Double for that position. Clearly, the fourth row is most favored by a small amount.
